Universal Follow-Up Planner
Keep track of your appointment, organize your medicine bottles, and write down questions to ask your doctor.
It is very common to forget or confuse medicine instructions after leaving the ER. Put all your pill bottles (both prescription and over-the-counter medicines) directly into a bag and take them with you to your clinic visit so your doctor can review them.

- Appointment Scheduling Friction: "Scheduling the appointment at the ED, not asking the patient to call, roughly doubles completion. RCT: 59% vs. 37% [S648]. A separate RCT connecting patients directly to the referral provider by phone/text: 49.3% vs. 23.4% (HR 2.4) [S649]." (from
00c §3) - Medication Recall Gap: "Medication information was most prone to being forgotten or distorted [S100]." (from
00 §1) - Teach-Back Retention Lever: Teach-back and structured doctor-question preparation produce an AOR of 14.89 for medication knowledge retention and 3.86 for follow-up adherence. (from

Heart Failure Daily Weight & Fluid Log
Weigh yourself every single morning right after using the bathroom, before eating breakfast or drinking liquids.
The water pill didn't fix your heart. It just emptied the tank. Water pills remove extra fluid buildup, but they do not heal the underlying heart muscle. Do not change your water pill dose on your own without calling your clinic. Ask your doctor if repeat blood tests are needed to check your potassium and kidneys.
Daily Weight & Swelling Record
Weigh yourself at the same time each morning, after the bathroom and before breakfast. The trend is what your doctor reads, not any single number.
Heart Failure Warning Signs: Return to the ER Immediately
- Sudden weight gain of about 4 to 5 lbs (2 kg) over 3 days, especially if you feel short of breath.
- Shortness of breath while sitting still, or waking up suddenly in the night gasping for air.
- Unable to speak in full sentences without stopping to catch your breath.
- Coughing up pink or bubbly, frothy spit.

Atrial Fibrillation Follow-Up Checklist
A short record for the days between your ER visit and your follow-up appointment, not something to keep forever. The main job: make sure you are on your blood thinner and can keep getting it.
Rate- or rhythm-control medicine calms the fast, uneven heartbeat you can feel. The blood thinner handles the stroke risk you cannot feel. They work on two separate parts of the heart, so fixing one does nothing to the other. Feeling normal is never a reason to skip a dose.
The newer blood thinners (apixaban, rivaroxaban, dabigatran, edoxaban) wear off in about 12 hours, and no routine blood test catches a missed dose. If you take warfarin, keep your diet steady and keep your INR blood-test appointments. If cost is the problem, say so at your visit. There are cheaper options and assistance programs.
Did You Take Your Blood Thinner?
One quick check a day until your follow-up. This is a record for your appointment. It does not judge or score anything.
Atrial Fibrillation Warning Signs: Return to the ER Immediately
- Sudden face droop, arm weakness, or trouble speaking: call 911. A blood thinner lowers stroke risk but does not remove it. Go even if you took every dose.
- Bleeding signs: black or tarry stools, blood in the urine or stool, vomiting blood, a sudden severe headache, or new confusion.
- Rate not holding: worse palpitations, chest pain, shortness of breath, or fainting or nearly fainting.
- Rate medicine too strong: a very slow pulse, fainting, or feeling you might pass out while on a rate-control pill.
Being older or prone to falls is usually not, by itself, a reason to stop a blood thinner. The stroke it prevents is far more likely to harm you than a fall-related bleed. This is a conversation to have with your doctor, not a decision to make by stopping the medicine on your own.
Before Your Follow-Up
Where this came from
Source note: dx-30-atrial-fibrillation.md
- Two separate mechanisms: "the mechanism that causes symptoms (a fast, irregular ventricular rate) and the mechanism that causes stroke risk (a stagnant, non-contracting atrial appendage) are anatomically and physiologically separate processes. Fixing one does nothing, by itself, to fix the other"
[S1476] (§1) - Rate/rhythm control does not remove stroke risk: "any apparent stroke-prevention edge for rhythm control disappeared entirely once at least 70% of patients were adequately anticoagulated"
[S1477][S1478] (§2) - Silent AFib: "Roughly 10–40% of people with AFib have no symptoms at all"; "absence of symptoms is not evidence of absence of stroke risk"
[S1477][S1476][S1479] (§3) - Missed-dose window: "DOACs have a relatively short effect window (roughly 12 hours), a single missed dose … can create a real window of low drug levels and increased stroke vulnerability, with no routine blood test to catch the lapse"
[S1509][S1508] (§6) - Breakthrough stroke on treatment: "breakthrough stroke still occurs in roughly 3% per year even on a DOAC, so any FAST-positive presentation is a real emergency regardless of medication adherence"
[S1503][S1473] (§4) - Rate-control overshoot: "too much of that effect (from a high dose, drug interaction, or added medication) can overshoot into dangerously slow heart rates or low blood pressure"
[S1505][S1473] (§4) - Follow-up window and who: "a follow-up visit in the first 1–2 weeks to reassess heart rate, symptoms, and confirm anticoagulation is actually being taken"; "Cardiology involvement (vs. primary care alone) after a new AFib diagnosis is associated with reduced stroke and death"
[S1506][S1473] (§5) - Fill and afford it: "an ED discharge should explicitly confirm the anticoagulation prescription is filled and affordable, and that a specific specialty follow-up appointment is actually scheduled"
[S1511][S1473] (§8) - Falls are not a stop reason: "A patient would need to fall roughly 295 times per year for the fall-related bleeding risk of warfarin to outweigh its stroke-prevention benefit"; "fall risk is not, by itself, a valid reason to withhold anticoagulation"
[S1499][S1487] (§7) - Left out on purpose: the CHA₂DS₂-VASc score is not shown as something to self-calculate (§9; DECISIONS.md 2026-08-01); resting-pulse home monitoring (only relevant when a clinic asks for it, so it is a question to raise, not a logged number); pediatric AFib (§7); and the cerebral-microbleed / reversal nuance, which the note says "needs to lead with 'this is a conversation for your specific doctor'" (§7, §10).
Blood Clot Follow-Up Checklist
A short record for the days between your ER visit and your follow-up. The first 2 to 3 weeks are the highest-risk time (for the clot and for the medicine), so the main job is staying on your blood thinner.
Blood thinners stop the clot from getting bigger. Your body clears the clot that is already there on its own, slowly, over weeks to months. That gap is why the first 2 to 3 weeks stay the highest-risk time (for the clot traveling and for bleeding from the medicine), even though you are being treated.
Take every dose exactly as prescribed. Do not stop or lower it when you feel better. Feeling better means the symptoms eased, not that the clot is gone, and almost everyone needs at least about 3 months. Walking is good for you; avoid contact sports and high-injury activity because of bleeding risk. If you take warfarin, keep leafy greens steady rather than avoiding them. If cost is a problem, say so at your visit.
Your Leg and How You Are Feeling
One quick check a day until your follow-up. A record for your appointment. It does not score anything.
Blood Clot Warning Signs: Return to the ER Immediately
- New or worse shortness of breath, sharp chest pain when you breathe, or coughing up blood: call 911. A piece of clot may have traveled to the lungs.
- The affected leg getting more swollen, more painful, or more red despite treatment: the clot may be extending.
- Bleeding signs: black or tarry stools, blood in the urine or stool, vomiting blood, a sudden severe headache, or new confusion.
- Fainting, feeling faint, or a racing heart.
A clot in the leg and a clot in the lungs are the same process in two places. Many proximal leg clots already have a small, silent clot in the lungs, and about half of people with a lung clot never had any leg symptoms. So watch for the breathing signs above even if you were told it is “just a leg clot.”
Before Your Follow-Up
Where this came from
Source note: dx-29-dvt-pe.md
- Does not dissolve the clot: "Anticoagulants do not dissolve existing clot. They stop new fibrin from forming and halt further clot growth, while the body's own, much slower fibrinolytic (clot-breakdown) system gradually recanalizes the vein over weeks to months"
[S1445] (§2) - Highest-risk window: "The first 2–3 weeks carry the highest risk of the clot itself progressing or embolizing. More than half of recurrent VTE events, and nearly three-quarters of major bleeding events, cluster in this early window"
[S1446] (§2) - One process, two locations: "30–60% of proximal DVTs have a silent PE already present, and only about half of PE patients with a confirmed DVT ever had leg symptoms at all"
[S1444] (§1) - Feeling better is not the clot resolving: "Feeling better reflects symptom resolution, not clot resolution or elimination of recurrence risk. Every patient needs a minimum of about 3 months of treatment"
[S1446][S1447] (§5) - Walking, not bed rest: "early walking reduces the venous stasis that drives clot formation in the first place… The activity that should genuinely be avoided is contact sports or other high-injury-risk activity, because of bleeding risk, not walking or normal daily movement"
[S1446][S1447][S1454] (§5) - Recurrence on treatment: "Roughly 2% of patients on adherent, therapeutic anticoagulation still have a recurrent VTE event, so new or worsening symptoms should never be waved off as 'just part of recovery'"
[S1446][S1451] (§4) - Warfarin and vitamin K: "The actual target is steady, consistent vitamin K intake… A normal, balanced diet without drastic swings is the goal; this doesn't apply to DOACs at all"
[S1454][S1465][S1445] (§5) - Follow-up cadence: "Early contact, 48 hours to 7 days after discharge… A dedicated visit around 3 months, to decide how long anticoagulation should continue"
[S1447][S1448] (§6) - Compression stockings, honestly: "stockings are most reliably useful for symptom relief (reducing swelling and discomfort) rather than for preventing PTS outright"
[S1454][S1456] (§3) - Fill and afford it: "ensuring equitable access to affordable anticoagulation (DOAC cost/coverage specifically), scheduled early follow-up, and clear written return precautions is a concrete, actionable way this content can help close part of this gap"
[S1469] (§8) - Left out on purpose: the PESI / sPESI / Hestia disposition scores are clinician tools, not for self-scoring (§9; DECISIONS.md 2026-08-01); the pregnancy, cancer, and pediatric anticoagulant specifics (§7); long-term post-thrombotic-syndrome management (§3).
Broken Bone: Pain & Recovery Log
Track your pain day by day while you are in the splint or cast. The direction your pain is heading (down, or up) is the thing that matters most.
A broken bone rebuilds in stages. It often hurts much less within 2 to 3 weeks, long before the bone is strong. Keep the splint or cast on until your follow-up doctor says the fracture, not the pain, is ready.
For the first 48 hours especially, keep the limb above heart level. Elevation, ice, and loose (never tight) support reduce pain and swelling. For itching, blow cool air from a hairdryer into the cast; never push anything inside. Keep it dry. Most simple, non-displaced fractures need pain medicine only as needed, not on a schedule.
Daily Pain Record
Pain that is dropping is the normal course. Pain that climbs, especially despite the medicine, is the warning below. Do not wait it out.
Broken Bone Warning Signs: Return the Same Night
- Pain that is out of proportion to the injury, or pain that keeps getting worse even though you are taking the pain medicine that should control it. This is the earliest and most important warning. Return the same night. Do not wait for morning. Permanent muscle and nerve damage can happen within 6 to 10 hours.
- Severe pain when someone gently straightens your fingers or toes.
- New numbness or tingling, or a limb that feels tense, full, or unusually hard.
- Pale skin, a cold limb, no pulse, or fingers or toes you cannot move: these are late signs.
- Normal color, warmth, and a pulse do not rule this out. Do not cut off your own cast. Return instead.
A child who cannot describe the pain will often show it a different way: increasing agitation, increasing anxiety, and needing more pain medicine than the injury seems to explain. If diabetes has affected the feeling in your hands or feet, the pain warning may not work. Have a concerning cast checked the same day rather than waiting.
Before Your Follow-Up
Where this came from
Source note: 33-fracture-splint-cast-care.md
- Pain resolves before strength: "Healing time is set by fracture type and healing stage, not by pain, and pain often resolves well before the bone is actually strong enough. Over-immobilizing 'just to be safe' isn't harmless either"
[S1594] (§9) - Escalating pain is the earliest sign: "Pain that is out of proportion to the injury, or pain that isn't controlled by the pain medicine that should be working: this is the earliest and most reliable sign, and it's the one patients themselves can recognize before anything looks visibly wrong"
[S1601][S1603] (§5) - The time window: "Irreversible muscle and nerve death can occur within 6–10 hours of sustained elevated pressure"; any of these signs "is a same-night return, not a 'call in the morning'"
[S1603] (§5) - A normal pulse is not reassurance: "Pale skin, a cold limb, an absent pulse, and inability to move the fingers/toes are late findings that mean damage may already be underway. A normal-feeling pulse is not reassurance"
[S1602] (§5) - The three A's in children: "In children who can't clearly describe pain, the surrogate to watch for is the 'three A's': increasing agitation, anxiety, and analgesia requirement that doesn't add up to the visible injury"
[S1604] (§5) - Diabetic neuropathy blunts the warning: "peripheral neuropathy blunts the very pain signal that's supposed to warn about a too-tight cast, a pressure sore, or early compartment syndrome, so diabetic patients… need closer follow-up and a lower threshold for a same-day cast check"
[S1619][S1620][S1618] (§7) - Elevation: "keep the limb above heart level, especially in the first 48 hours. This is a genuinely low-risk, high-value instruction, not a formality"
[S1599] (§6) - Itching: "The evidence-based fix is directing cool air from a hairdryer into the cast"; scratching with an object "is the single most dangerous common cast behavior"
[S1605] (§3, §9) - Pain medicine mostly as-needed: "64% of children took no pain medicine at all after a cast was applied… Displaced fractures were the exception. They needed analgesia about 5.5 times more often"
[S1608] (§3) - Left out on purpose: fracture-specific weight-bearing timelines and immobilization durations, which the note says are "never a single universal number" and must be fracture-specific (§4); growth-plate follow-up specifics (§7); and the NSAID-and-bone-healing question, which the note flags as an unresolved open question (§10).
Fainting: Episode Record
One entry each time you faint or nearly faint, up to your follow-up. The pattern around a faint (the warning, the position, what you were doing) is how your doctor tells the harmless kind from the kind that needs a closer look.
Most fainting is the harmless reflex kind: a brief drop in blood flow to the brain that fixes itself once you are lying flat. But about 1 in 10 people who faint has a heart cause, and the two are told apart by the pattern around the faint. That is why writing down what happened matters.
Feeling warm, sweaty, sick, or seeing spots before a faint is not the faint starting. It is your body trying to keep blood going to your brain, and it is your window to act. Lie down and raise your legs. If a clinician has already told you your faints are the reflex kind, crossing your legs and squeezing your muscles hard also helps. If someone else faints, get them flat and lift their legs. Do not sit them up. Ask your clinician about driving; the rules vary by state.
Each Time You Faint or Nearly Faint
Fainting Warning Signs: Return to the ER Immediately
- Fainting during exercise, or while lying down.
- A faint with no warning at all.
- Chest pain, shortness of breath, or a racing or irregular heartbeat with the faint.
- Several faints close together.
- New weakness, numbness, trouble speaking, or confusion that lasts after you wake.
- A close family member who died suddenly of a heart problem, especially before age 50.
Crossing your legs and tensing your muscles works by pushing pooled blood back toward your heart. It does nothing for a heart-rhythm cause. Only use it if a clinician has already told you your faints are the reflex kind.
Before Your Follow-Up
Where this came from
Source note: 11-syncope.md
- About 1 in 10 is serious: "~1 in 10 has a serious condition found within 30 days"
[S471] (header, §1) - Told apart by the pattern: "most fainting is benign (reflex/vasovagal, no increased risk of dying), but a minority is the heart's warning shot, and the two are distinguishable by features a patient can learn"
(§0; §4 table [S483]) - The prodrome is compensation: "Those warning signs are not the faint starting. They are your nervous system fighting to keep your pressure up, and they are your window to act"
[S1940] (§0b) - Lie flat, legs up, and the bystander error: "If someone faints, get them flat and lift their legs. Don't sit them up in a chair. That keeps blood away from the brain"
[S1943][S1940] (§0b) - Counterpressure is for reflex faints only: "The maneuvers this note teaches are for reflex syncope. In cardiac syncope they do not work, because the deficit is not venous pooling"
[S483][S477] (§0b) - Return precautions: "fainting during exertion or while lying down; no warning before it; chest pain, shortness of breath, or palpitations with it; several faints close together… known family history of sudden cardiac death (esp. <50)"
[S469][S477] (§6) - One follow-up visit is worth it: "Even low-risk patients benefit from one outpatient visit to confirm the cause and prevent recurrence"
[S477] (§9) - Monitoring window: "91.7% of arrhythmic events in med/high-risk appear within 15 days → supports 15-day outpatient monitoring after discharge"
[S482] (§3) - Counterpressure maneuvers work: "physical counterpressure maneuvers… genuinely reduce episodes"; "Lower-body maneuvers raise blood pressure more effectively than upper-body ones"
[S488][S1942][S477] (§5, §0b) - Driving: "Driving: state-regulated; discuss local law. Reassuringly, first-episode syncope did not raise subsequent crash risk above the general ED population"
[S490] (§5) - Left out on purpose: the Canadian Syncope Risk Score is a clinician tool, not for self-scoring (§2; DECISIONS.md 2026-08-01); midodrine and fludrocortisone dosing (§5, §10); pediatric breath-holding spells (§7).
Ankle Sprain: Recovery Log
Track your pain and how much you are moving over the next couple of weeks. For most sprains, moving early beats resting, and a few weeks of balance work is what keeps it from happening again.
For most sprains, early movement beats rest. People who put weight on it and use a brace get back to normal stairs in about half the time of people who rest it or use a cast. Put weight on it as pain allows unless your discharge plan says otherwise, and start gentle ankle motion and light resistance in the first 1 to 3 days.
Ice and elevation help swelling in the first days. The thing that changes your future: once you can stand comfortably on it, do a few weeks of single-leg balance and heel-raise work. About 1 in 5 people who skip it sprain the same ankle again. Balance training roughly halves that.
The Exercises
Start the motion ones in the first 1 to 3 days. Add balance work once you can stand on it comfortably. A few weeks of it roughly halves your chance of a repeat sprain.
Ankle alphabet
Trace the letters A to Z in the air with your big toe. Move the ankle, not the whole leg.
Motion · from day 1–3Band pushes, four ways
Loop a band around your foot. Push down, pull up, turn out, turn in. Slowly, and only as far as does not hurt.
Strength · from day 1–3Single-leg balance
Stand on the injured leg. Hold something at first, then let go. Eyes open to start, then try it with them closed.
Balance · once standing is comfortableHeel raises
Rise onto your toes, then lower slowly. Both feet together first, then the injured one on its own.
Strength · once standing is comfortableDaily Recovery Record
Weight-bearing and the exercises are the two things that change how this ends. Tick what you actually did.
Ankle Sprain Warning Signs: Return or Get It Rechecked
- No improvement by 5 to 7 days, or your recovery stalls instead of steadily getting better.
- Still cannot put weight on it, increasing pain or swelling, a visible deformity, or new sharp pain over the ankle or foot bones.
- Pain far worse than the injury looks, pain above the ankle joint, or an injury that twisted the foot outward: this can be a different, higher sprain that needs different care.
- New numbness, or a cold or pale foot.
- Signs of infection.
An X-ray only rules out a broken bone. It does not show the ligament sprain itself, a high (syndesmotic) sprain, or cartilage and tendon injuries. That is why pain that is not following the expected course is a reason to go back, not to wait it out longer.
Before Your Follow-Up
Where this came from
Source note: 26-ankle-sprain.md
- Move early, do not rest it: "Early weight-bearing + functional bracing beats rest/cast on every outcome measured (return to sport, return to work, swelling, satisfaction), and a 4-week cast produces a longer time to recovery than early loading"
[S1370] (§9) - Recovery times: "return to normal stair climbing at ~5.5 days with a functional brace vs. ~12 days with an elastic wrap" (Grade I); "~11.7 days with brace + functional support vs. ~28 days when treated in a cast" (Grade II)
[S1370] (§1) - Start rehab in 1 to 3 days: "Range-of-motion and light resistance work can begin 1–3 days post-injury; this isn't a reason to delay follow-up, it's guidance for right now"
[S1373] (§5) - Balance training roughly halves re-injury: "A structured balance/neuromuscular program (~8–12 weeks) meaningfully lowers the chance of spraining it again (NNT ≈ 5)"
[S1370] (§5) - The four exercises shown, and their phasing: "Ankle range of motion (alphabet tracing, dorsiflexion) and resistance-band work in all four directions (eversion, inversion, plantar-/dorsiflexion)" started "from day 1–3"; then "Single-leg balance eyes open → eyes closed, firm → unstable surface; single-leg heel raises" once "full loading is comfortable"
[S1373][S1369] (§5b) - Why no list of banned movements: the note states that "the literature does not enumerate banned exercises… A handout that invents such a list is going beyond its sources," so the diagrams show what to do and the rule stays "pain-free range"
(§5b) - Home program about equals supervised PT: "no clinically important difference in excellent recovery at 3 months between supervised physiotherapy plus usual care (43%) and usual care alone (37%)"
[S2092] (§5b) - Chronic instability is common: "Roughly 40% of patients progress to CAI"
[S1370][S1381] (§7) - A normal X-ray only rules out fracture: "A normal X-ray only rules out fracture. It doesn't exclude ligament injury (the sprain itself), syndesmotic injury, osteochondral lesions, or peroneal tendon injury"
[S1373] (§9) - Pain out of proportion means go back: "If pain is disproportionate to what a 'normal' sprain should feel like, or isn't following the expected course, that's the signal to go back, not to wait it out longer"
[S1373] (§3) - Return precautions: "No improvement by 5–7 days, or the recovery stalls… Pain out of proportion, tenderness above the ankle joint itself, or an eversion mechanism: possible high (syndesmotic) sprain"
[S1373] (§6) - Topical NSAIDs first-line: the acute musculoskeletal pain guideline "gives its strongest recommendation to topical NSAIDs (± menthol) as first-line"
[S1380] (§4) - Left out on purpose: the Ottawa Ankle Rules are a clinician bedside tool, not a self-check (§2); Grade III immobilization specifics (§5b, §10); and a list of "movements not to do," which the note says "the evidence declines to answer directly" (§5b).
Skin Infection: Redness Recovery Tool
A short record until your follow-up. The redness can spread for a day or two after the antibiotic starts. That is expected. By about 72 hours it should be clearly improving.
When the antibiotic starts killing bacteria, they release substances that briefly stir up more inflammation, so the redness can keep advancing for a day or two before it turns around. By about 72 hours it should be clearly improving. What you are seeing is your immune response, not the germs, which is why the swelling and color take longer to fade than the infection takes to clear.
Track the edge: mark the border of the redness with a pen, or photograph it next to a ruler. Redness still improving by 72 hours is on track. No improvement, or worsening, by 48 hours needs another look. If the infection is on your leg, treating athlete's foot between your toes is one of the best ways to stop this happening again; that is often how the bacteria got in.
The Redness, Day by Day
Day 1 is the day you started the antibiotic. Redness still creeping past the mark on day one or two is expected. What matters is that it is clearly improving by about 72 hours.
Skin Infection Warning Signs: Return to the ER Immediately
- Pain far worse than the skin looks, tight swelling, dark or blistering skin, or the area getting rapidly worse. A rare but serious infection has to be ruled out. Go now.
- Fever, chills, or feeling generally unwell.
- A red streak spreading away from the area.
- No improvement, or worsening, by 48 hours.
- If the infection is near an eye: pain with eye movement, vision changes, or a bulging eye.
Red, warm, swollen skin is not always infection. A blood clot, a vein problem, or a skin reaction can look identical. Redness in both legs at once is almost never infection. If the antibiotic is not working as expected, the diagnosis itself may need another look.
Before Your Follow-Up
Where this came from
Source note: 21-cellulitis-abscess.md
- Looks worse on day two: "Early apparent progression on appropriate therapy is expected and does not necessarily mean failure. IDSA attributes it to the sudden destruction of bacteria releasing enzymes and other products that transiently amplify local inflammation even as the organisms are being killed"
[S879] (§0b) - Why marking the border works: "Marking the border works because the border is expected to move, and the patient needs a way to distinguish 'expected early spread' from 'failing'"
[S1063] (§0b) - The 72-hour and 48-hour checkpoints: "Erythema should improve by roughly 30% at 72 hours; swelling and warmth can persist to day 10 without indicating failure"; "If unimproved or worse at 48 hours, consider a resistant pathogen or an alternative diagnosis"
[S1063][S1066] (§5) - Immune response, not germs: "What you're seeing is your immune response, not the germs themselves, which is why the swelling and colour take longer to fade than the infection takes to clear"
[S1066] (§0b) - Athlete's foot is the portal: "Treating athlete's foot is one of the most effective things you can do to stop this happening again. The cracks between your toes are how bacteria got in"
[S1978] (§0b) - Often not cellulitis at all: "the initial diagnosis wrong in up to 41% of cases versus expert assessment"; "bilateral leg erythema is essentially never infectious"
[S1065][S1067] (header, §1) - Pain out of proportion always matters: "most red, warm skin is not an emergency, but 'pain out of proportion to how it looks' always is"
[S1065][S1067] (§0, §6) - Five days is enough if improving: "Duration: 5 days, extended only if not improved within that window"; "Residual inflammation at day 5 is not treatment failure"
[S879][S1066] (§4.1) - Recurrence prevention: "For patients with ≥2 same-leg episodes within 24 months, compression stockings reduce recurrence (NNT = 4)"
[S1063] (§4.3) - Left out on purpose: the LRINEC score, a clinician lab tool the note says is poorly sensitive and "not validated in children" (§2.2, §11); antibiotic selection and dosing (§4.1, §11 provider addendum); wound packing after drainage, covered in the separate incision-and-drainage aftercare topic (§4.2).
Shoulder Pain: Exercise & Recovery Log
For rotator cuff–related shoulder pain. Exercise is first-line treatment here, and doing it at home works about as well as doing it with a physiotherapist, but only if it actually gets done.
Do Not Start These Exercises If Any of This Applies
This log is for ordinary rotator cuff pain. Some shoulder problems get worse with a general exercise sheet, so check with the clinician who examined you first if:
- Your shoulder was dislocated, or it feels like it slips or gives way.
- You had a significant injury and the arm is weak. A full-thickness tear needs assessing, not stretching.
- You have numbness, tingling or weakness down the arm.
- You are generally very flexible or have been told your joints are loose. Stretching a loose shoulder can make things worse.
The Exercises
Gentle movement in the painful phase; strengthening as the pain settles. Aim for most days. Doing a little often beats doing a lot occasionally. Stretch to the point of tightness, never into pain.
Pendulum swings
Lean forward, let the arm hang loose, and swing it gently in small circles. Let gravity do the work. The arm should be relaxed.
Movement · twice a dayCross-body stretch
Bring the sore arm across your chest and pull it gently closer with the other hand. Hold about 30 seconds, 3 to 5 times.
Stretch · dailyBand external rotation
Elbow tucked in at your side and bent to a right angle. Rotate the forearm outward against a light band, then return slowly.
Strength · once or twice a dayShoulder blade squeezes
Draw both shoulder blades back and down, as if holding something between them. Hold a few seconds, then release.
Posture · through the dayRegular beats occasional. In studies, spreading the same total amount of exercise across the week worked while cramming it into one session did not. A few minutes most days is the target.
Expect weeks, not days. Movement usually improves after about 3 to 4 weeks of doing this regularly. Stretch only to the point of tightness. Pushing into real pain does not speed it up.

Shoulder Warning Signs: Get It Looked At
- New or increasing weakness: trouble lifting the arm at all, or holding it up.
- The shoulder slipping, catching or giving way.
- Numbness or tingling down the arm, or a cold or pale hand.
- Pain that is getting worse rather than settling after several weeks of doing the exercises.
- Fever, redness or swelling over the joint.
Before Your Follow-Up
Where this came from
Source note: 00f-stretching-and-home-exercise.md §2, §6, §9
- Exercise is first-line, and no single exercise wins: "Exercise is first-line for all three: rotator cuff related shoulder pain (RCRSP)/subacromial pain, adhesive capsulitis, and glenohumeral OA. But effect sizes are modest, delivery formats are largely equivalent, and no single named exercise has proven superior to another"
[S2169][S2170][S2171] (§2) - Home is about as good as supervised: a meta-analysis of home-based exercise for nonspecific shoulder pain found it "equal to other conservative treatments including supervised care, and superior to no treatment (pain MD −1.47; function SMD −0.81, large)"
[S2182]; GRASP (n=708) found a supervised tailored program "not superior to a single best-practice-advice physiotherapy session" over 12 months[S2180] (§2) - The two stretches shown are the best-evidenced named stretches in the KB: double-blind RCT in symptomatic overhead athletes: "pain fell (sleeper −2.2, cross-body −1.5 on 0–10) and internal rotation improved ~15° each over 4 weeks, with no difference between techniques"
[S2175][S2176][S2177] (§2) - Strengthening dose: "home exercise 1–2×/day over 12 weeks with periodic supervised progression"
[S2180][S2181]; posterior capsule stretches "3–5 reps, ~30 s hold, once daily or 3×/week for 4 weeks"[S2175][S2176]; pendulum/ROM "twice daily"[S2174] (§2 Dose) - Frequency beats cramming: a volume-equated trial found "3×/week at 2 min/session increased ankle range of motion and reduced stiffness, while 1×/week at 6 min/session did not"
[S2265] (§6) - Time to benefit: range of motion improves after "~3–4 weeks of regular stretching"
[S2257][S2259] (§6) - Intensity: "to the point of tightness or slight discomfort, not pain"
[S2257][S2266] (§6). For frozen shoulder specifically, high-intensity into-pain stretching does not clearly outperform pain-limited stretching[S2171] (§2) - The exclusion card is taken verbatim from §2's "Who should NOT get a shoulder exercise sheet": traumatic full-thickness cuff tear (tears enlarge on exercise-only management: "enlargement in ~59% in one series")
[S2172]; suspected instability, where "stretching a hypermobile capsule is counterproductive"[S2187]; acute post-dislocation, which needs proprioceptive work "not capsular stretching"[S2173][S1369][S2188]; and any red flag needing examination and imaging first[S2190][S2172] - Left out on purpose: Holmgren's finding that a specific strengthening program cut the proportion choosing surgery from 63% to 20%
[S2181]is the most quotable shoulder result in the KB, but §2 flags that it was "a specific, progressed, therapist-initiated program, not a generic sheet," so it is not claimed for this module. Glenohumeral OA and adhesive capsulitis are separate conditions with different programs and are not covered here. No named exercise is presented as superior, because none is.
Knee Osteoarthritis: Exercise & Recovery Log
Exercise is first-line for knee arthritis, ahead of tablets in the guidelines. The realistic shape is being taught it once, then doing it at home.
The Exercises
Thigh strengthening plus walking, at least three times a week. Walking is not the warm-up. In the largest analysis it was the single most useful thing on the list.
Straight-leg raises
Lying down, keep the knee straight and lift the whole leg a hand's width off the floor. Lower it slowly.
Thigh strength · 3+ days a weekSit-to-stands
From a firm chair, stand up and sit back down slowly, without using your hands if you can. This is the one that shows up in daily life fastest.
Thigh strength · 3+ days a weekWalking
Steady walking, built up gradually. Not a warm-up for the real exercises. This is one of the most useful things you can do for an arthritic knee.
Aerobic · most daysHeel slides
Lying down, slide the heel toward your bottom to bend the knee as far as is comfortable, then straighten it out again.
Movement · dailySome aching during and after exercise is expected with an arthritic knee and does not mean you are wearing it out. Settle back a level if it is still worse the next day, rather than stopping altogether.
The benefit lasts. In studies, improvements in pain and function were still there 2 to 6 months after the formal program had finished, but only for people who kept going.
Daily Record
Tick what you actually did. Walking minutes are worth logging honestly. The trend is the useful part.
Knee Warning Signs: Get It Looked At
- The knee locking, catching, or giving way.
- A knee that becomes hot, red and swollen, especially with fever. That needs same-day assessment, not exercise.
- Sudden severe swelling after an injury.
- Calf pain or swelling, or new shortness of breath.
- Pain getting steadily worse over weeks despite the exercises.
Pain around or behind the kneecap in a younger person is often a different problem with a different exercise program, one that includes hip strengthening, not just thigh work. Worth asking your clinician which one you have before settling into this routine.
Before Your Follow-Up
Where this came from
Source note: 00f-stretching-and-home-exercise.md §4, §6, §9
- Exercise is first-line, ahead of drugs: "Guidelines place exercise and self-management first-line, ahead of pharmacology, with intra-articular steroid reserved for inadequate response"
[S2209] (§4) - The program shown: "quadriceps-focused strengthening including straight-leg raise, both weight-bearing and non-weight-bearing work, aerobic/walking activity, and range-of-motion work, ≥3×/week"
[S2210][S2211] (§4) - Why walking is given its own card rather than treated as a warm-up: a 2025 network meta-analysis (217 RCTs, 15,684 patients) found "aerobic exercise the most beneficial modality," large short/mid-term pain improvement SMD −1.10 to −1.19
[S2211][S2212] (§4) - Versus tablets: exercise had a larger effect than NSAIDs (SMD 0.54, 95% CI 0.19–0.89) and ranked ahead of NSAIDs and opioids, though between-treatment differences were small and certainty low
[S2213] (§4) - Benefit outlasts the program: "Moderate effect on pain and function, sustained 2–6 months after treatment ends"
[S2431] (§4) - Why the copy says "taught once, then done at home" rather than "replaces physio": a 2025 meta-analysis (10 RCTs, 917 patients) found "supervised statistically superior to home-based" for pain (SMD −0.45) and disability (SMD −0.28), favouring "initial supervision transitioning to home maintenance"
[S2215]. §4 notes this diverges from ankle and shoulder, "where home matched supervised"(§4) - Dose: "≥2–3 days/week; daily is most effective," and weekly volume is the driver: "≥5 minutes per week per muscle, performed ≥5 days/week"
[S2257][S2258] (§6) - The patellofemoral callout exists because §4 gives it a different program: the 2018 International Patellofemoral Research Retreat consensus favours "hip-focused plus knee-focused exercise combined" over either alone
[S2216][S2209], and the two are equivalent as standalone programs with "neither reaching the MCID alone"[S2218] (§4) - Left out on purpose: stretching is not presented as a core component. For patellofemoral pain the consensus and Cochrane review "do not identify stretching as an independently effective component"
[S2216][S2217] (§4). Deyle's physiotherapy-versus-steroid comparison[S2214]is a treatment-choice finding for the clinic, not an instruction for a patient at home. Injection and surgical options are out of scope for a home-exercise log.
High Blood Pressure Home Diary
Take your blood pressure morning and night using an upper-arm cuff after resting quietly for 5 minutes.
Resting matters: About 1 out of every 3 people with very high blood pressure see their numbers drop into a safer range after resting quietly for 30 minutes. Pain, anxiety, stress, or a full bladder can cause temporary spikes.
Accurate technique: Use an automatic upper-arm monitor. Avoid caffeine, smoking, and exercise for 30 minutes before testing. Empty your bladder. Sit quietly for 5 minutes with your back supported, feet flat on the floor, and your arm resting at heart level. Do not talk. Take 2 readings 1 minute apart and record them.
Do not change medicines on your own: Never stop, start, or change blood pressure pills without speaking with your doctor. Dropping your blood pressure too fast can cause dangerous dizziness, falls, or reduced blood flow to your brain.
7-Day Blood Pressure Log
High Blood Pressure Warning Signs: Return to the ER Immediately
- Brain symptoms: Sudden severe headache, confusion, trouble speaking, or sudden loss of vision.
- Blood vessel symptoms: Sudden severe chest pain or sharp, tearing pain in your back.
- Kidney symptoms: Unable to pass urine at all, or blood in your urine.
- Heart symptoms: Chest tightness, pressure, or sudden severe trouble breathing.

Asthma & COPD Breathing Diary
Keep track of your quick-relief rescue puffs, nighttime coughing or wheezing, and daily breathing stability.
Rescue vs. Daily Controller: Quick-relief rescue inhalers (like albuterol) open tight airways during an attack. Daily controller inhalers (steroids) treat the hidden swelling to prevent attacks and protect your lungs. Needing your rescue inhaler frequently means your daily prevention plan needs review with your doctor.
Steroid pill burst: Take your prescribed steroid pills (such as prednisone) for the exact number of days directed. Do not stop early even if you feel completely better. Bring all your inhalers and your spacer chamber to your clinic visit so your doctor or nurse can check your breathing technique.
Daily Breathing & Inhaler Record
Breathing Emergency Signs: Return to the ER Immediately
- Inability to speak in full sentences without gasping for breath.
- Lips, gums, or fingernails turning blue or gray.
- Rescue inhaler provides zero relief or wears off in under 1 hour.
- Chest or neck muscles sucking in deeply around your ribs when breathing.
- Silent chest warning: Breathing very fast and hard with little or no wheezing sound can mean your airways are so tight that barely any air is moving. This is an immediate life-threatening emergency.

Source notes: topics/08-asthma-copd.md & 07-dyspnea.md
- Follow-Up Cadence: Asthma follow-up within 2–7 days (or 1–2 days if severe); COPD contact at 48 hours and clinic within 1 week. (from

08-asthma-copd.md §10)
Kidney Stone Pain & Hydration Log
Keep track of your waves of pain, whether you caught a stone, and your fluid tolerance.
Do not force gallons of water: Drink a normal, comfortable amount of fluid. Do not force gallons of water during severe pain attacks. Extra water cannot push a stuck stone out, but it will back up behind the stone like a clogged pipe and make your pain and vomiting much worse.
Strain every time you pee: Strain your urine every single time you go to the bathroom. If you catch a stone or grit, save it in a clean, dry container and bring it to your doctor. Testing the stone in a lab is the only way to know what caused it and how to prevent future stones.
Daily Kidney Stone Record
Infected Kidney Stone Warning: Return to the ER Immediately
- Fever of 100.4°F (38.0°C) or higher, or shaking chills accompanied by back or side pain (this is a medical emergency meaning an infected, blocked kidney).
- Persistent severe vomiting with inability to keep any fluids down.
- Unable to pass urine at all despite feeling an urgent need to go.
Where this came from
Source notes: Kidney Stone KB
- Hydration During Active Colic: Do not force large volumes of water during active colic; excess fluid increases renal pelvic pressure behind the blockage without speeding expulsion.
- Stone Composition Analysis: "Composition analysis should be done whenever a stone is captured."
- Infected Stone Emergency: Fever (≥ 100.4°F / 38°C) or chills accompanied by flank pain denotes infected obstruction (a urologic surgical emergency).
Concussion Symptoms & Activity Diary
Rate your symptoms daily (0 = None, 1 = Mild, 2 = Moderate, 3 = Severe) and track your daily walking minutes.
Do not stay in a dark room for days: Total rest in a dark room past 24 to 48 hours actually makes recovery take longer. Light, gentle walking that does not trigger bad symptoms helps your brain recover faster.
Driving and sports: Do not drive, play sports, or return to hard physical work until your doctor examines you and gives you medical clearance.
Daily Symptom Diary
Head Injury Warning Signs: Return to the ER Immediately
- Repeated vomiting or a headache that keeps getting worse.
- One pupil larger than the other, slurred speech, or trouble waking up.
- New clumsiness, loss of balance, or numbness/weakness in arms or legs.
- New confusion, severe agitation, or seizure activity.
If you are an older adult or take blood thinners (like aspirin, Plavix, Eliquis, Xarelto, or warfarin), bleeding around the brain can build up very slowly over days or even weeks after a head bump. Watch closely for gradual memory loss, increasing sleepiness, or new balance trouble, even if your ER CT scan was normal on the day of injury.
Where this came from
Source notes: topics/06-concussion.md
- Active Recovery: "The old advice (total rest in a dark room) actually makes concussion recovery take longer." Strict rest past 24–48 hours is no longer recommended; early graduated sub-symptom activity speeds recovery. (from
06 §8 [S249-S273]) - Normal CT Scan Meaning: "A normal CT does not mean 'no concussion.'" CT rules out acute surgical bleeding, not the underlying microscopic brain injury. (from
06 §8 [S262]) - Delayed Bleed Warning: Older adults and patients taking blood thinners require close monitoring for delayed-onset subdural hematomas.
Low Back Pain & Mobility Log
Keep track of your daily walking minutes and pain levels to share with your primary care provider.
Staying active beats bed rest: Strict bed rest delays healing and makes back muscles stiffer. Short, frequent walks throughout the day help break muscle spasms. About half of people recover significantly within 2 to 3 weeks.
Medicine guidance: Anti-inflammatory pain pills (like ibuprofen or naproxen) provide modest relief, but use caution if you are older or have kidney, stomach, or heart conditions. Opioids and sedatives (benzodiazepines) are not recommended. They carry serious risks without speeding up long-term recovery.
Daily Mobility Record
Spine Emergency Signs (Cauda Equina): Return to the ER Immediately
- Loss of bowel or bladder control (accidental leaking or unable to urinate at all).
- Numbness or loss of feeling in your groin, buttocks, or saddle area.
- New or progressive weakness in your legs or feet (such as your foot dragging, catching toes, or stumbling).
- High fever combined with severe new back pain.

Sickle Cell Pain Crisis Recovery Diary
Log your pain levels, response to home crisis medicines, and fluids to share with your sickle cell clinic or doctor.
Follow your personalized home pain management plan agreed upon with your sickle cell specialist. Keep oral hydration steady and talk with your doctor about staying on your daily hydroxyurea to prevent future crisis events.
Daily Crisis & Pain Record
Sickle Cell Red Flags: Return to the ER Immediately
- Fever of 101.3°F (38.5°C) or higher, or sudden shaking chills. Because sickle cell affects how your spleen fights infection, a fever requires emergency evaluation and hospital antibiotics right away.
- Chest pain, cough, or trouble breathing (can be Acute Chest Syndrome).
- Sudden severe weakness on one side of your body, slurred speech, or numbness (stroke signs).
- Sudden severe swelling or pain in your belly (spleen crisis).
- Severe pain that is not controlled despite taking your prescribed home crisis medicines.
Where this came from
Source notes: topics/sickle-cell-disease & 00e-pain-management
- Diagnosis & Context: "Unlike most complaint notes, the patient already knows the diagnosis. The ED encounter is almost always a vaso-occlusive (pain) crisis in someone who has had this disease since birth, has likely had dozens of prior crises, and has often had a bad prior ED experience." (from
topics/sickle-cell-disease §0) - Individualized Care Principle: "The single highest-yield message is not diagnostic. It's that individualized, rapid pain treatment works better than one-size-fits-all protocols, and that the biggest gap between guideline and practice is a system failure (undertreated pain, underused hydroxyurea) rather than a patient one." (from
topics/sickle-cell-disease §0) - Return Precaution Objective: "AFTER angle: because the outcome gap here concentrates in complication rates and treatment intensity rather than time-to-first-evaluation, a discharge resource's most direct lever is making the return-precaution criteria in §4 explicit and easy to act on." (from
topics/sickle-cell-disease §4) - Fever Emergency Threshold [S1312]: "Fever ≥ 38.5°C (101.3°F)" requires immediate emergency evaluation due to functional asplenia and the rapid lethality of encapsulated bacterial sepsis. (from
topics/sickle-cell-disease §4 [S1312])
Low Blood Sugar Recovery Tool
Two records: one for any low you have, and a simple place to write down your sugar readings. Take both to your follow-up.
- Take 15 grams of fast sugar. Glucose tablets or gel work fastest, better than juice, candy, or milk.
- Wait 15 minutes, then check again.
- Still low? Do it again.
- Once your number is back to normal, eat a real snack or meal. This is the step people skip. The fast sugar fixes the emergency, but if insulin or other diabetes medicine is still working in your body, skipping the snack leaves you at real risk of a second drop hours later.
If your low came from glipizide, glyburide, or glimepiride: these pills keep working for about a day, so a second dip can happen any time in the next 24 hours, most often in the first several hours and overnight. Keep eating regular meals and snacks today, check your sugar again before bed, and try not to be alone tonight. If a low comes back, treat it the same way (15 and 15) and come back if it will not stay up.
Not chocolate, not a candy bar, for the fast fix. Fat slows sugar down and protein makes your body release more insulin, the opposite of what you need right then. They are fine as the snack in step 4.
If someone cannot safely eat or drink (confused, not waking up, or unable to swallow), they need glucagon, not food. Do not try to put anything in their mouth. The ready-to-use kinds (nasal spray, or a shot that comes already mixed) are the ones to have on hand.
Log 1: When You Have a Low
One entry each time you feel low or get a low reading. Hours matter more than days here, so note the time.
Log 2: Your Sugar Readings
Only if your own doctor asked you to check. This keeps your numbers in one place for your appointment. It does not score them, judge them, or tell you what any of them mean.
| Day & time | Before or after a meal? | Reading | Note |
|---|
Go Back to the ER Now If
- Confusion, not waking up properly, or a seizure that does not fully clear up after treatment.
- A low that comes back even though you took sugar, rechecked, and ate.
- The low happened after drinking alcohol, especially on an empty stomach. Alcohol stops your liver from making new sugar, so these lows can be slow and drawn out instead of one quick episode.
- Any diabetes medicine was taken by accident, or too much was taken on purpose. That always needs to be checked in person, not watched at home.
- A child swallowed a diabetes pill. Get them seen right away even if they look completely fine.
Do not just skip your next insulin dose on your own. It feels like the safe move, but it can send your sugar too high instead, which brings its own danger. Ask the doctor who prescribes it what to change.
Do not drive until your symptoms are completely gone and you have checked your sugar and it is back to normal. Your judgment and reaction time are genuinely off during a low and right after one.
A low bad enough to need someone else's help is worth a real conversation about your medicines, not just "be more careful." Having had a serious low is the strongest sign that another one could happen.
If you have stopped feeling lows coming on, that can get better. A few weeks of carefully avoiding any lows can bring some of the warning signs back.
Where this came from
Source notes: 38-hypoglycemia.md
- 15-15 rule: "Take 15 grams of fast-acting sugar. Glucose tablets or gel are the best-studied and fastest option, outperforming juice, candy, milk, and other common choices in head-to-head comparisons" [S1729][S1579]; "Wait 15 minutes, then recheck. If still low, repeat. Once it's back to normal, eat an actual snack or meal"
[S1722][S1720](§2). - Why the follow-up meal matters: "The 15-15 rule corrects the emergency, but if insulin or a similar medication is still active in the body, skipping the follow-up snack or meal genuinely risks a second drop. That extra step isn't optional"
[S1722][S1728](§5). - Fat and protein are the wrong fast fix: "fat slows down how fast sugar gets absorbed, and protein actually triggers more insulin release, which works against what's needed in the moment"
[S1729][S1579](§2). - Glucagon, not food, for the unsafe-to-swallow patient: "Modern ready-to-use glucagon (nasal spray or pre-mixed injection, not the older kind that had to be mixed first) is strongly preferred, because the mixing step on the older version is a well-documented source of dosing mistakes"
[S1724][S1722][S1725](§2). - Sulfonylurea recurrence: "these drugs have a delayed, prolonged effect, and the low can genuinely recur several hours after the first one is treated and resolved"
[S1727][S1725](§4). The KB lists this as a return-to-ED item; on Dr. Tameze-Rivas's ruling (2026-09-11) it is framed here as a reason to keep eating and recheck, because the reader has already been assessed and discharged on that medicine. Return criteria stay symptom-based (a low that comes back). The 24-hour window is not in the KB note (which says "several hours"); it comes from standard EM references on sulfonylurea duration of action and the usual 24-hour observation recommendation (StatPearls, Sulfonylurea Toxicity); confirmed by Dr. Tameze-Rivas, 2026-09-11. - Alcohol-related lows: "alcohol directly blocks the liver's ability to make new sugar, so these lows can be delayed and drawn-out rather than a single quick event"
[S1727][S1725](§4). - Pediatric ingestion (recognition only): "a single sulfonylurea pill can cause a dangerous low in a small child, and it can take up to 18 hours to show up"
[S1734][S1735](§6). The observation-period protocol is disposition detail and is deliberately not in the patient copy. - Do not self-skip insulin: "This isn't automatically the safe move. It risks the opposite problem (high blood sugar, and in some cases a dangerous complication called DKA). The right response is reviewing the dose and timing with the prescriber"
[S1726](§5). - Driving: "Driving should stop until symptoms are fully resolved and blood sugar has been rechecked as normal"
[S1722](§3). - Repeat lows warrant a regimen review: "A prior serious low is the single strongest predictor of another one"
[S1724][S1722](§3). - Hypoglycemia unawareness is partly reversible: "a few weeks of deliberately avoiding any lows can restore some of that lost warning system"
[S1722][S1718](§1). - Excluded on purpose: octreotide dosing for sulfonylurea-induced lows and insulinoma workup are both marked "provider-tier... out of scope for patient-facing content" (§8.1, §8.3). Post-bariatric rescue dosing is marked "an active area of study... flagged as evolving rather than settled" (§8.2) and is therefore absent from this module.
High Blood Sugar Recovery Tool
Check your blood sugar every 2 to 4 hours while you are sick. Track your numbers, ketones, and how you feel between now and your follow-up.
Do not stop your insulin because you are sick or not eating.
- Being sick raises how much insulin your body needs. Stopping it is what causes the emergency.
- Your long-acting insulin keeps going even on a day you cannot eat.
- Follow the plan on your discharge papers for how much. If you do not have one, call your doctor. Do not skip.
- Check your sugar every 2 to 4 hours while you are sick.
- Check ketones if your sugar is high or you feel sick.
- Keep drinking fluids and getting some carbohydrate in.
- Check your bottles for these names: canagliflozin, dapagliflozin, empagliflozin.
- On these, a serious emergency can happen with a blood sugar under 200.
- The warning signs look different: less thirst and less urinating than you would expect, but more nausea, vomiting, and belly pain.
- What makes it more likely: skipping meals, eating low-carb, alcohol, and being sick.
Your Glucose & Ketone Log
High blood sugar is tracked across hours, not days. Write the clock time with each check. This log records what you write; it does not score it or tell you what any number means.
Go Back to the ER Now If
This list does not cover everything. If you feel seriously unwell, trust that and go.
- You are throwing up and cannot keep liquids down.
- Your blood sugar is over 300 even after taking your insulin.
- Your ketones are large, or they are not coming down.
- Your breathing is fast and deep.
- Belly pain, feeling sick to your stomach, or breath that smells sweet or fruity.
- You are confused, or very hard to keep awake.
- You are very dried out.
- A fever along with a high sugar.
Get a child seen right away if they suddenly start drinking and urinating far more than usual, are losing weight, or have started wetting the bed again after being dry.
Before Your Follow-Up
- Bring this with you. Your doctor can see the pattern. You do not have to remember it.
- Your follow-up date is on your discharge papers. Keep it even if you feel fine by then. If you were not given one: most people should be seen within a month. Sooner, within one to two weeks, if your medicines changed or your sugars have been running high. If your diabetes is new, or has been hard to control, aim for within a week.
- If cost is why you have been skipping or stretching your insulin, say so at the visit. Making insulin last longer is one of the things that brings people back to the emergency department. There are cheaper options and assistance programs, and your doctor cannot help with a problem they do not know about.
- Why high sugar makes you thirsty and up all night: above roughly 180 to 200, your kidneys can no longer hold sugar back and it spills into your urine, pulling water out with it. That is the constant urinating, the thirst, and the drying out.
- Why you are exhausted even though your sugar is high: the sugar is stuck outside your cells, so your cells are still short of fuel.
- What the A1c actually is: sugar sticks to red blood cells, and those cells live about three months, so it is a three-month average, not a report card on yesterday.

[S623](§5), and insulin rationing causes DKA[S635](§9). The note calls this "the topic where a structural driver (insulin cost/rationing) directly causes the emergency, making the disparities section unusually concrete and actionable" (§0). Stated as an action a patient can take; no disparity statistic appears in the visible copy. - Excluded on purpose: the §1 DKA/HHS diagnostic thresholds (pH, bicarbonate, anion gap, effective osmolarity) are provider-grade and stay out of patient copy; §4a drug selection, HbA1c targets, and diet/exercise evidence are PCP territory; §5 transition dosing and the insulin-reduction percentage are prescribing; §3 disposition criteria and §8 disparities statistics are out of scope.
Allergy & Reaction Log
Monitor for any returning symptoms over the next 24 to 72 hours following an allergic reaction.
If you were prescribed an epinephrine auto-injector (like EpiPen), keep two unexpired doses with you at all times. Epinephrine is the only medicine that stops a life-threatening allergic reaction. Allergy pills (like Benadryl) only help with mild itching. They cannot open a swollen airway or raise dangerously low blood pressure.
Post-Reaction Check Record
Severe Allergic Reaction (Anaphylaxis): Return to the ER Immediately
- Throat tightness, hoarse voice, or difficulty swallowing.
- Wheezing, chest tightness, or trouble breathing.
- Dizziness, feeling faint, lightheadedness, or confusion.
- Hives or skin swelling paired with vomiting, stomach cramps, or diarrhea.

Dehydration & Volume Recovery Tool
A focused 24 to 72 hour record of your weight, thirst, fluid intake, and bathroom trips.
When you are very sick and losing fluids, your doctor may ask you to temporarily pause certain daily medicines that can stress your kidneys or drop your blood sugar too low.
- S = Sulfonylureas: diabetes pills like glipizide or glimepiride (hold if blood sugar is low)
- A = ACE inhibitors: blood pressure pills ending in "-pril" (like lisinopril)
- D = Diuretics: "water pills" (like furosemide, Lasix, hydrochlorothiazide)
- M = Metformin: diabetes medicine
- A = ARBs: blood pressure pills ending in "-sartan" (like losartan, valsartan)
- N = NSAIDs: pain relievers like ibuprofen, Advil, Motrin, naproxen, Aleve
- S = SGLT2 inhibitors: diabetes pills ending in "-flozin" (like Jardiance, Farxiga)
When to restart: Restart these medicines within 24 to 48 hours once you are no longer vomiting or having diarrhea, and are eating and drinking normally again.
Why a written plan matters: The most common problem is forgetting to restart your medicines after feeling better, which leaves your heart and blood pressure unprotected. Always agree on a clear restart plan with your clinic. If you have heart failure, kidney disease, or diabetes, your doctor will usually check your kidney blood tests 1 to 2 weeks after recovery.
Common Myths About Drinking Water
- "You must drink 8 glasses of plain water a day": There is no scientific basis for this. Much of the daily water your body needs comes naturally from the food you eat.
- "Coffee and tea dehydrate you": Regular amounts of coffee or tea do not cause dehydration or make you pee away more fluid than you drink.
- "IV drips work better than drinking liquids": For mild to moderate dehydration, drinking oral electrolyte solutions works just as well as an IV hospital drip.
- "Sports drinks are best for stomach bugs": Sports drinks, apple juice, and soda have too much sugar and far too little sodium. The extra sugar can actually pull water into your bowels and make diarrhea worse.
- "You can never drink too much water": Drinking huge volumes of plain water without electrolytes can dangerously dilute your blood and cause brain swelling (water intoxication).
24 to 72 Hour Recovery Log
Age check: As we get older, our thirst alarm stops working well. You can be genuinely low on water and not feel thirsty at all. In adults over 60, checking urine color is also not a reliable way to judge hydration.
Dehydration Red Flags: Return to the ER Immediately
- New confusion, extreme sleepiness, or trouble waking up (the strongest sign that you need hospital IV fluids).
- Fainting, dizziness, or feeling like you are about to pass out when standing.
- No urine for 8 to 12 hours (or 6 to 8 hours for a child; no tears when crying for a baby).
- Unable to keep liquids down despite small frequent sips (vomiting 10 or more times in 24 hours).
- Bloody or black, tar-like stools.
- Fever of 102.2°F (39°C) or higher.
- Chest pain, shortness of breath, or a racing heart that will not slow down.
- In hot weather: confusion, agitation, or collapse is heat stroke until proven otherwise.
- In older adults: Severe dehydration often presents as sudden confusion, sleepiness, or falls rather than normal thirst. Don't assume it is "just normal aging" or "being tired."
- Adrenal conditions: If you take steroid pills or have an adrenal gland condition, severe weakness and dehydration can be an adrenal crisis, which feels identical to dehydration but requires emergency steroid medicine.
- Diabetes: If your blood sugar is very high and you are excessively thirsty and urinating constantly, this can be a serious metabolic emergency (such as DKA).
- Internal fluid loss: Dizziness when sitting or standing up, even if your blood pressure was normal while lying down in the ER, can mean ongoing internal fluid or blood loss.

Stomach Bug & GI Illness Recovery Tool
Track vomiting, diarrhea, fluids, and food across the expected 2 to 7 day recovery window.
If your discharge paperwork already told you whether to take anti-diarrhea medicine or antibiotics for this, follow that. It was written for you. If it didn't say: hold off on Imodium (loperamide) or antibiotics for now and call your doctor. Blood without fever can point to an infection where those medicines make kidney damage more likely, not less.
Yellow or green vomit in a baby: If a baby's vomit is yellow or green, get medical care right away. This can mean a blocked intestine, which is a surgical emergency. The color alone doesn't tell you if it's safe or dangerous, so don't wait to see if it gets worse.
Take Ozempic, Wegovy, or a similar medicine? Nausea and vomiting are common side effects, especially when your dose goes up. If it is severe or doesn't improve, call the doctor who prescribed it. Do not change your own dose. Ongoing vomiting can lead to severe dehydration and kidney injury.
Stomach Bug Facts & Home Care
- Expected timeline: A typical stomach bug (like Norovirus) lasts about 2 to 3 days (about 75% of people recover within 3 days). Vomiting first, followed by diarrhea a day later, is the normal order of the illness. It does not mean you are getting worse.
- You rarely need antibiotics: Most stomach bugs are viral. Antibiotics do not kill viruses and can cause harsh bowel infections (like C. diff). Only about 9% of acute diarrhea cases benefit from antibiotics.
- Eat when you can: You do not need to starve yourself for 24 hours or stick strictly to the BRAT diet (bananas, rice, applesauce, toast). Start eating small amounts of normal food as soon as you feel hungry. Eating actually helps your intestines heal faster.
- Drink oral rehydration solutions: Sip oral rehydration drinks (ORS) or electrolyte fluids. Avoid apple juice, sports drinks, and soda. They have too much sugar and can worsen diarrhea.
Daily Stomach Bug Log
Stomach Bug Warning Signs: Return to the ER Immediately
Losing too much fluid is the most common and serious danger of diarrhea and vomiting. Return immediately if you notice:
- Can't keep any liquids down for more than 12 to 24 hours.
- Signs of severe dehydration: little or very dark urine, dizziness when standing up, dry mouth, or a racing heartbeat.
- Stools that have red blood or look black and tar-like.
- High fever (over 101.3°F / 38.5°C) or severe belly pain.
- Confusion, extreme sleepiness, or trouble waking up.
- Symptoms lasting 7 days or longer, or getting worse after starting to improve.
Critical signs in babies and children:
- Yellow or green vomit (needs immediate emergency check for a bowel blockage).
- Forceful (projectile) vomiting after feeding in a baby under 2 months old.
- Severe, colicky belly pain where a child cries and pulls their knees to their chest, or passing red "jelly-like" stool.
- A baby crying without tears, having a sunken soft spot on top of the head, or being unusually hard to wake up.
- Recent antibiotics: If you recently took antibiotics or stayed in a hospital, tell your doctor. Severe diarrhea can be a specific bacterial infection called C. diff.
- Appendicitis: Severe belly pain that shifts to your lower right side and hurts when walking or coughing can be appendicitis, not just a bug.
- Diabetes: If you have diabetes and cannot stop throwing up, check your blood sugar and ketones right away. A serious acid buildup (DKA) can start out feeling like food poisoning.
- Older adults: If you are over 70 with a history of heart or blood vessel disease and develop sudden severe belly cramps followed by bloody stool, seek immediate emergency care to check the blood supply to your intestines.

Source notes: 13-nausea-vomiting.md & 14-diarrhea.md
- Course & Sequence: "Norovirus lasts ~2–3 days; 75% recover within 3 days [S565][S564] (§4). Vomiting first, then diarrhoea a day or so later, is the expected order, not the illness getting worse [S1946][S1950] (§0b)." Course reference: "self-limited, 3–7 days (norovirus 2–3). Acute <14 d; persistent 14–30 d (think parasites); chronic >30 d"
[S568](§5). - Loperamide / STEC Contraindication: "In simple watery diarrhoea in immunocompetent adults it reduces stool volume safely, but in inflammatory or invasive infection, slowing transit is precisely the harm... Loperamide: watery, non-bloody only; avoid in bloody/inflammatory/STEC/C. diff; contraindicated in children <3 (deaths reported)"
[S563][S562](§0b, §3). - STEC and HUS Safety Warning: "⚠️ STEC and HUS, the load-bearing safety fact: in Shiga-toxin E. coli, antibiotics increase the risk of hemolytic-uremic syndrome (toxin release, flora disruption), and antimotility agents/opioids also raise HUS and neurologic risk; NSAIDs risk AKI."
[S582][S583](§3). - Pediatric Death Rate: "IDSA advises avoiding loperamide at any age in inflammatory diarrhoea or diarrhoea with fever (strong recommendation), and not at all in children under 18. Deaths reported in 0.54%, all in children under 3"
[S562](§0b). - Afebrile Bloody Diarrhea Nuance: "Bloody diarrhea without fever should raise STEC suspicion: get CBC/BMP/LDH/smear and monitor, and hold antibiotics/loperamide"
[S582][S583](§3). - GLP-1 Agonist Rule: "Nausea and vomiting are common gastrointestinal adverse effects of GLP-1 receptor agonists and are often most noticeable during dose escalation [S2626]... persistent or unusually severe symptoms should be reported to the prescribing clinician rather than managed by changing the dose independently [S2626][S2627]." (13 §4)
- Bile-Stained Vomit in Infants: "bile-stained vomit in babies and children may look yellow or green; colour alone is not diagnostic and no evidence-based shade threshold separates safe from dangerous [S2628]... In an infant, suspected bile-stained vomiting needs immediate evaluation to exclude malrotation or another blockage [S559][S560][S2628]." (13 §6/§7)
- US Diarrhea Mortality Factor: "Volume depletion is the most common risk factor for diarrhea-related death in the US"
[S562](14 §6). - Hydration & Early Diet: "Oral rehydration solution (ORS) is first-line for mild-moderate dehydration in adults: 2–4 L reduced-osmolarity ORS... Not apple juice/Gatorade/soda [S562]. Eat as soon as tolerated. Early normal diet shortens illness; the BRAT diet and 'no solid food for 24 h' are not supported [S562]."
