Red flags / send to ED#
- Sudden onset unilateral numbness/weakness, facial droop, speech or vision changes (possible stroke/TIA)
- Progressive motor weakness, new gait instability, or bowel/bladder dysfunction
- Suspected myelopathy: hand clumsiness + gait imbalance + hyperreflexia
- Acute vascular compromise of a limb (cold/pale limb, severe pain, diminished pulses)
Key history#
- Onset and tempo: sudden vs gradual; intermittent vs constant; progressive vs stable
- Distribution:
- Face/arm/leg sudden: vascular concern
- Dermatomal arm/leg: radiculopathy
- Median vs ulnar hand: entrapment
- Stocking-glove/bilateral: peripheral neuropathy
- Associated symptoms: weakness, pain (neck/back), gait change, autonomic symptoms
- Triggers: neck motion, elbow flexion, repetitive wrist use, prolonged standing
- Comorbidities: diabetes, thyroid disease, B12 risk, alcohol use, CKD; chemo history
- Falls, head/neck injury
Focused exam#
- Neuro screen: strength, sensation, reflexes; compare sides
- Localization:
- Median nerve (CTS): thenar strength, Phalen/Tinel
- Ulnar neuropathy: intrinsic strength, Tinel at cubital tunnel
- Radiculopathy: dermatomal sensory changes, reflex changes, Spurling/SLR
- Gait and balance if symptoms suggest myelopathy or neuropathy
- Vascular: pulses/cap refill if limb ischemia concern
- Quick “is it central?” checks: face involvement, aphasia, visual field deficit, pronator drift, asymmetry with simultaneous stimulation (when feasible)
Differential (quick pattern recognition)#
Common/likely (outpatient)#
| Diagnosis | Keywords patients use | Key clues | Focused exam clues | Initial next step |
|---|---|---|---|---|
| Carpal tunnel syndrome | “Night numbness,” “shaking helps” | Median distribution; worse at night | +Phalen/Tinel; thenar weakness late | Night splint + ergonomics |
| Ulnar neuropathy (cubital tunnel) | “Ring/small finger numb” | Worse with elbow flexion/leaning | +Tinel cubital tunnel | Night elbow extension + avoid pressure |
| Cervical radiculopathy | “Numbness down arm” | Neck pain + dermatomal symptoms | Reflex/sensory changes; +Spurling | Conservative care + PT |
| Lumbar radiculopathy | “Sciatica,” numbness down leg | Back pain + leg symptoms | +SLR; dermatomal findings | Conservative care + PT |
| Peripheral neuropathy | “Both feet/hands tingle” | Bilateral stocking-glove; chronic | Distal sensory loss | Targeted labs + symptom plan |
Can’t-miss / urgent#
| Diagnosis | Keywords patients use | Key clues | Focused exam clues | Initial next step |
|---|---|---|---|---|
| Stroke/TIA | “Sudden numbness” | Abrupt onset; vascular risk | Focal deficits | ED now |
| Cervical myelopathy | “Clumsy hands,” unsteady | Progressive; gait changes | Hyperreflexia, Hoffmann | ED/urgent spine eval; MRI |
| Cauda equina | “Can’t pee,” saddle numb | Urinary retention/incontinence | Objective weakness/sensory loss | ED now; emergent MRI |
Workup#
- For classic mild entrapment neuropathy: treat first and reassess; no routine imaging.
- EMG/NCS when diagnosis unclear, symptoms persistent >6–8 weeks, or weakness/atrophy present; often before procedural referral.
- MRI spine (urgent) for myelopathy/progressive motor deficit; (non-urgent) for persistent radiculopathy when results change management.
- For stocking-glove neuropathy pattern: consider targeted labs (verify local protocol): A1c/glucose, B12, TSH, CBC/CMP; expand based on history.
- For sudden-onset focal numbness/weakness: ED pathway for stroke/TIA evaluation (do not “watch and wait”).
Initial management#
- Prioritize safety and function: splinting/position changes, PT, and activity modification.
- Treat pain enough to maintain sleep and function; avoid sedating meds in older adults when possible.
- Escalate early for objective weakness or progressive symptoms.
- B12 deficiency treatment (if B12 <200 pg/mL or borderline with elevated MMA):
- Cyanocobalamin 1000 mcg PO daily x 1–2 months, then 1000 mcg daily ongoing (or weekly)
- IM B12 1000 mcg weekly x 4 weeks, then monthly (if malabsorption suspected)
- Symptom-first cross-links:
- Hand-predominant median/ulnar patterns: consider also Hand numbness and Wrist pain.
- Neck/back-associated patterns: see Neck pain and Back pain.
Management by diagnosis#
Entrapment neuropathy (CTS/cubital tunnel)#
Education:
- Positioning and ergonomics often reduce symptoms; weakness/atrophy needs faster escalation
- Night symptoms are common because of wrist/elbow positioning during sleep
- Most improve with conservative treatment; surgery reserved for persistent or severe cases
Treatment:
- Night splinting (wrist neutral for CTS; elbow extension for cubital tunnel)
- Avoid provoking compression (leaning on elbows; prolonged wrist flexion/extension)
- Consider hand therapy/ergonomic changes
| Drug | Dose | Contraindications | Monitoring | Cost | Notes |
|---|---|---|---|---|---|
| Ibuprofen | 400–600 mg TID PRN | GI bleed, CKD, CV disease | Cr if prolonged | $ | Short-term for acute flares; limited evidence for entrapment |
| Gabapentin | 100–300 mg QHS | CKD (reduce dose) | Sedation | $ | If significant neuropathic pain; not first-line for mild CTS |
Corticosteroid injection (CTS): consider if splinting fails; provides temporary relief; hand surgery referral if recurrent or severe.
- Consider EMG/referral if persistent symptoms, constant numbness, or weakness/atrophy
Follow-up: 4–8 weeks (sooner if weakness).
Radiculopathy (cervical or lumbar)#
Education:
- Symptoms often improve over weeks; watch for weakness progression
- Most radiculopathy resolves without surgery; PT and time are first-line
- Red flags requiring urgent evaluation: progressive weakness, bowel/bladder changes
Treatment:
- PT and activity modification without immobilization; avoid prolonged provoking positions (sustained neck flexion, prolonged sitting) when relevant
| Drug | Dose | Contraindications | Monitoring | Cost | Notes |
|---|---|---|---|---|---|
| Ibuprofen | 400–600 mg TID with food | GI bleed, CKD, CV disease | Cr if prolonged | $ | First-line for acute pain |
| Naproxen | 500 mg BID with food | Same as ibuprofen | Same | $ | Longer duration |
| Gabapentin | 100–300 mg TID, titrate as tolerated | CKD (reduce dose) | Sedation | $ | For radicular/neuropathic component |
| Prednisone | 40–60 mg x 5–7 days (no taper needed for short course) | Active infection, uncontrolled DM | Glucose | $ | Consider for severe acute radiculopathy; limited evidence |
Muscle relaxants (cyclobenzaprine 5–10 mg QHS): short-term if significant spasm; avoid in elderly.
- Consider imaging/referral if persistent disabling symptoms or objective neuro deficits
Follow-up: 1–2 weeks if significant symptoms; urgent re-eval for progressive weakness or bowel/bladder symptoms.
Peripheral neuropathy (suspected)#
Education:
- Often chronic; focus on reversible contributors and symptom control
- Diabetic neuropathy is most common; tight glucose control slows progression
- Protective footwear and regular foot exams prevent complications
Treatment:
- Address metabolic causes (glucose control, B12/thyroid issues as relevant) and remove neurotoxic exposures when possible
- Protective foot/hand care and fall-risk counseling when feet are involved
Neuropathic pain management:
| Drug | Dose | Contraindications | Monitoring | Cost | Notes |
|---|---|---|---|---|---|
| Gabapentin | 100–300 mg QHS, titrate to 300–600 mg TID (max 3600 mg/day) | Reduce dose in CKD (eGFR <60) | Sedation, edema, falls | $ | First-line; start low in elderly (100 mg QHS); takes 2–4 weeks |
| Pregabalin | 50 mg TID or 75 mg BID, titrate to 150–300 mg BID | CKD (reduce dose); HF (edema) | Sedation, edema, weight | $$ | Alternative to gabapentin; faster titration; controlled substance |
| Duloxetine | 30 mg daily x 1 week, then 60 mg daily | Hepatic impairment, uncontrolled glaucoma, MAOIs | LFTs if hepatic risk; BP | $ | First-line if depression comorbid; avoid in severe CKD |
| Amitriptyline | 10–25 mg QHS, titrate to 50–100 mg | Cardiac disease, glaucoma, urinary retention, elderly | Anticholinergic SE; ECG if cardiac hx | $ | Effective but avoid in elderly (Beers); helps sleep |
| Capsaicin cream 0.075% | Apply TID–QID to affected area | Avoid mucous membranes, broken skin | Burning sensation (expected) | $ | Adjunct; takes 2–4 weeks; wash hands after |
| Lidocaine 5% patch | Apply to painful area x 12h on/12h off | None significant | Skin irritation | $$ | Good for localized pain; safe in elderly |
Elderly patients: prefer gabapentin (low dose), duloxetine, or topicals. Avoid TCAs (anticholinergic, falls).
Follow-up: 4–8 weeks with lab review; titrate medications as tolerated.
Follow-up#
- Reassess in 1–2 weeks if symptoms are progressive, function-limiting, or diagnosis is uncertain.
- Reassess in 4–8 weeks for entrapment/neuropathy once treatment started.
- Urgent return for sudden weakness, trouble speaking, severe gait changes, or bowel/bladder dysfunction.
- If not improving after 4–8 weeks, escalate (EMG/NCS, imaging if it will change management, and referral based on localization).
When to refer:
- Neurology: unclear diagnosis after initial workup, progressive symptoms despite treatment, suspected myelopathy, atypical presentations, consideration of immunotherapy for inflammatory neuropathies
- Hand surgery: CTS with thenar atrophy/weakness, failed conservative treatment >3 months, or patient preference for surgical evaluation
- Spine surgery: progressive motor deficit, myelopathy, cauda equina, or radiculopathy with severe/progressive weakness
Patient instructions#
- Use the recommended splint at night and avoid positions that provoke symptoms.
- Take breaks from repetitive hand/wrist activities and avoid leaning on elbows.
- Use over-the-counter pain options if safe for you.
- Seek urgent care now for sudden weakness/numbness of the face/arm/leg, trouble speaking, or new bowel/bladder problems.
Smartphrase snippets#
Carpal tunnel syndrome:
Hand numbness in median nerve distribution (thumb, index, middle fingers), worse at night, relieved by shaking. Positive Phalen/Tinel. No thenar atrophy or weakness. Consistent with carpal tunnel syndrome. Plan: night wrist splint in neutral, ergonomic modifications. Follow up 4–8 weeks. Return sooner if weakness develops. EMG if no improvement.
