Neuropathy means damage or disease of nerves. Nerves are the body’s electrical cables. They carry feeling (touch, temperature, pain), control muscles (movement, strength), and run automatic jobs (heart rate, blood pressure, sweating, digestion). When nerves are injured, the “signals” become weak, slow, or noisy. You may feel numbness, tingling, burning, shooting pain, or weakness. Sometimes blood pressure drops on standing, the stomach empties slowly, or the bladder doesn’t work well. Neuropathy can be mild and slow, or severe and fast. It can affect one nerve (focal), many nerves in one area (multifocal), or many nerves throughout the body (polyneuropathy). Some causes are common and treatable—like diabetes, vitamin lack, or trapped nerves—so careful testing matters.
Neuropathy means damage or disease of nerves. Nerves are like electrical cables that carry messages between your brain, spinal cord, and the rest of your body. When nerves are injured, messages may be slowed, misread, or completely blocked. This can cause numbness, tingling, burning pain, weakness, problems with balance, and sometimes trouble with body functions you do not control (like blood pressure or sweating). Neuropathy is a description of what is happening to nerves, not a single disease. Many different problems can lead to neuropathy, and it can affect one nerve, a group of nerves, or many nerves throughout the body.
Healthy nerves have two major parts. The axon is the long wire that carries the signal. The myelin sheath is the insulating layer that helps signals travel fast and cleanly. Some neuropathies hurt the axon. Some attack the myelin. Some affect the small, pain-temperature fibers, while others hit the large fibers that carry vibration, touch, and position sense. Understanding which part of the nerve is affected helps doctors choose the right tests and treatments.
Types of neuropathy
Peripheral neuropathy: This is the most common type. It affects the nerves outside the brain and spinal cord. It often starts in the longest nerves, so symptoms begin in the toes and feet, then may move up the legs and later the hands (“stocking-glove” pattern).
Sensory neuropathy: This mostly affects feeling. People notice numbness, tingling, pins-and-needles, burning, or sharp pains. Touch and temperature may feel wrong or painful.
Motor neuropathy: This mostly affects movement. People notice weakness, cramps, muscle loss, foot drop, or trouble with fine hand tasks.
Autonomic neuropathy: This affects the automatic nerves that control heart rate, blood pressure, digestion, bladder, sexual function, and sweating. Dizziness on standing, bloating, constipation, diarrhea, urinary problems, and heat intolerance can happen.
Small-fiber neuropathy: This targets the tiny pain and temperature nerves. People often have burning feet, stabbing pains, or painful sensitivity even when nerve conduction studies are normal. Skin biopsy can help confirm it.
Large-fiber neuropathy: This affects bigger fibers that carry vibration and position sense. People feel numb, unsteady, and have poor balance in the dark. Reflexes are often reduced.
Mononeuropathy: Damage to a single nerve, often from pressure or injury (for example, carpal tunnel syndrome affecting the median nerve).
Mononeuritis multiplex: Damage to multiple separate nerves in different places, often from inflammation of blood vessels (vasculitis) or other systemic diseases.
Polyneuropathy: Many nerves are affected in a similar way on both sides of the body. This is common in diabetes, toxins, or nutritional causes.
Demyelinating neuropathy: The insulating myelin is attacked, so signals slow down. Weakness with reduced reflexes is common. Guillain-Barré syndrome (acute) and CIDP (chronic) are key examples.
Axonal neuropathy: The wire itself is damaged. Signals are small or lost. Many toxic, metabolic, and hereditary neuropathies are axonal.
Acute vs. chronic: Acute neuropathies start over days to weeks; chronic ones develop over months to years.
Hereditary vs. acquired: Some neuropathies are genetic (like Charcot-Marie-Tooth). Most are acquired later in life from other conditions.
Autonomic neuropathy: automatic nerves; causes lightheadedness on standing, sweating changes, gut and bladder problems, erectile dysfunction.
Focal/entrapment neuropathies: a single nerve is compressed (e.g., carpal tunnel, ulnar neuropathy).
Proximal neuropathy: pain/weakness in the thighs/hips (can occur in diabetes).
Small-fiber neuropathy: tiny pain/temperature fibers; normal nerve tests but burning pain and reduced pin/temperature sense; often confirmed by skin biopsy.
Large-fiber neuropathy: vibration loss, numbness, poor balance, absent reflexes; nerve tests abnormal.
Immune-mediated neuropathies: the immune system attacks nerves (e.g., CIDP, anti-MAG, vasculitic neuropathy).
Hereditary neuropathies: genetic (e.g., Charcot–Marie–Tooth).
Toxic/chemotherapy-induced neuropathies: nerve injury from drugs or toxins.
Common causes of neuropathy
Diabetes: High blood sugar slowly poisons nerves and their blood supply. This is the most common cause worldwide. Good glucose control lowers risk and slows worsening.
Prediabetes and metabolic syndrome: Even mildly high sugars and insulin resistance can injure small fibers and cause burning feet.
Alcohol use disorder: Alcohol and poor nutrition damage nerves directly and by vitamin lack, especially thiamine (B1).
Vitamin B12 deficiency: Low B12 harms the myelin and the spinal cord. People feel numb and off-balance. The blood count may show anemia, but not always.
Too much or too little vitamin B6: Very high doses of B6 can cause severe sensory neuropathy, yet low B6 can also hurt nerves.
Thiamine (B1) deficiency: Seen with poor diet, alcoholism, or after bariatric surgery. Causes painful burning feet and weakness (beriberi).
Hypothyroidism: Low thyroid slows body processes and can cause numbness, tingling, and carpal tunnel.
Chronic kidney disease (uremia): Waste products build up and damage nerves, causing a symmetric, length-dependent neuropathy.
Liver disease: Toxins not cleared by the liver may irritate or damage nerves. Malnutrition may add to it.
Autoimmune diseases: Conditions like Sjögren’s, lupus, rheumatoid arthritis, celiac disease, and sarcoidosis can inflame nerves or their blood supply.
Inflammatory demyelinating neuropathies: Guillain-Barré syndrome (rapid onset after infections) and CIDP (slowly progressive) are immune attacks on myelin.
Infections: HIV, hepatitis C, Lyme disease, leprosy, and COVID-19 can injure nerves directly or through immune reactions.
Toxins and heavy metals: Arsenic, lead, mercury, and certain industrial solvents can cause axonal neuropathy.
Chemotherapy drugs: Agents like cisplatin, oxaliplatin, vincristine, and bortezomib commonly cause tingling, numbness, and pain in hands and feet.
Other medications: Isoniazid (without B6), amiodarone, nitrofurantoin, metronidazole, colchicine, and some statins (rarely) can injure nerves.
Entrapment/compression: Repeated pressure on nerves (carpal tunnel, ulnar at elbow, peroneal at fibular head) leads to pain, numbness, and weakness in that nerve’s territory.
Trauma: Cuts, fractures, or stretch injuries can directly damage a nerve.
Vasculitis and poor circulation: Inflamed or blocked small arteries starve nerves of blood and oxygen, causing painful, patchy neuropathy.
Amyloidosis and plasma-cell disorders: Abnormal proteins deposit in nerves or damage them indirectly (for example, AL amyloidosis, MGUS-related neuropathy).
Hereditary neuropathies: Genes can affect myelin or axons (for example, Charcot-Marie-Tooth). Family history and exam clues guide testing. Sometimes the cause remains idiopathic (unknown) even after evaluation.
Common symptoms
Numbness: A “dead,” cottony, or absent feeling in toes, feet, or fingers.
Tingling (paresthesia): Pins-and-needles, crawling, or buzzing sensations, often worse at night.
Burning pain: A hot, fiery, or scalding feeling in the soles or palms.
Electric-shock pains: Sudden zaps or stabbing jolts, sometimes triggered by touch.
Allodynia (pain from light touch): Even bedsheets or clothing can hurt.
Temperature sensitivity: Cold floors or warm water may feel painful or strangely intense.
Loss of vibration sense: People cannot feel a tuning fork on toes and feel “disconnected” from the ground.
Poor balance: Worsens in the dark because eyes can no longer “help” the weak position sense (proprioception).
Muscle weakness: Trouble climbing stairs, lifting toes (foot drop), or gripping objects.
Muscle cramps and twitching: Overactive or irritated nerves cause cramps, fasciculations, or tightness.
Wasting of muscles: Long-standing nerve damage lets muscles shrink, especially in feet and hands.
Loss of reflexes: The ankle jerk is often the first reflex to fade.
Foot injuries you do not notice: Cuts, blisters, or ulcers may go unnoticed due to numbness.
Autonomic symptoms: Dizziness when standing, a racing heart, abnormal sweating, dry eyes or mouth, digestive issues, erectile dysfunction, or bladder control problems.
Neuropathic itch or odd sensations: Itch without rash, a feeling of “wrinkled sock,” or walking on pebbles.
Diagnostic tests
A) Physical examination
Full neurological exam (sensation map): The clinician gently tests light touch, pinprick, and temperature in your feet, legs, hands, and arms. This shows where the nerve problem starts and how far it has spread.
Reflex testing: A small rubber hammer checks ankle and knee jerks. Reduced ankle reflexes are common in length-dependent neuropathy.
Muscle strength and bulk (MRC grading): The clinician checks for weakness, compares sides, and looks for muscle wasting. This helps separate motor nerve disease from muscle disease.
Gait and balance tests (Romberg, tandem walk): Standing with feet together and eyes closed or walking heel-to-toe reveals balance loss from large-fiber neuropathy.
B) Manual/bedside tests
Monofilament test (10-gram): A thin nylon filament is pressed on the skin to check protective sensation, especially in the feet. Failure to feel it signals risk for foot injuries and ulcers.
Vibration sense with a 128-Hz tuning fork: The fork on toe joints checks large-fiber function. Short or absent vibration times suggest large-fiber damage.
Pinprick and temperature discrimination: A disposable pin and warm/cool tools check small-fiber pain and temperature pathways.
Provocative maneuvers for entrapment (Phalen/Tinel): Wrist or elbow positions and gentle tapping over a nerve can reproduce tingling in carpal or ulnar tunnel syndromes.
C) Laboratory and pathological tests
Glucose panel (fasting glucose, HbA1c, ± 2-hour OGTT): Finds diabetes or prediabetes, the leading cause of polyneuropathy.
Vitamin B12 with methylmalonic acid (± homocysteine): Detects true B12 deficiency even when the blood level looks borderline.
Metabolic and endocrine panel (kidney, liver, thyroid): Creatinine and eGFR check kidney function; liver enzymes assess liver health; TSH (± free T4) checks for hypothyroidism.
Serum protein electrophoresis with immunofixation (± serum free light chains): Looks for abnormal proteins from plasma-cell disorders that can cause neuropathy and amyloidosis.
Autoimmune and inflammatory markers (as guided by history): ESR/CRP, ANA/ENA, SSA (Sjögren), rheumatoid factor, complement levels, ANCA, and others help uncover immune causes or vasculitis. Infectious screens (HIV, hepatitis B/C, Lyme when relevant) are often included.
Skin punch biopsy for intraepidermal nerve fiber density (IENFD): A tiny skin sample from the lower leg counts small nerve fibers. Low counts confirm small-fiber neuropathy when other tests are normal.
D) Electrodiagnostic tests
Nerve conduction studies (NCS): Surface electrodes measure signal speed and size across nerves. Slowed speed means demyelination; low amplitudes mean axonal loss. This separates demyelinating from axonal neuropathies and maps severity.
Electromyography (EMG): A very fine needle listens to muscles at rest and with movement. It shows whether weakness comes from nerve damage, muscle disease, or the spinal nerve root.
Autonomic function testing (as needed): Heart-rate variation with deep breathing, Valsalva ratio, tilt-table testing for orthostatic hypotension, and QSART (sweat testing) evaluate autonomic nerve fibers.
E) Imaging tests
MRI of spine/plexus/brain (when indicated): MRI looks for nerve root compression, plexus inflammation, or other structural causes that mimic or contribute to neuropathy.
High-resolution nerve ultrasound: Ultrasound can show swollen, compressed, or inflamed nerves (for example, median nerve swelling in carpal tunnel) and can guide injections.
Targeted imaging for complications or mimics: Foot X-rays or MRI can assess deformity, fractures, or suspected bone infection in people with severe diabetic neuropathy and ulcers; vascular imaging can be used if poor blood flow is suspected.

Drug Treatments for Neuropathic Pain
(Typical adult doses shown; dosing must be individualized and adjusted for age, kidney/liver function, drug interactions, and pregnancy. Start low, go slow.)
Duloxetine (SNRI)
Dose: 30 mg daily → 60 mg daily (some need 120 mg split). Morning if stimulating.
Purpose: first-line for painful diabetic neuropathy and other neuropathic pains.
Mechanism: increases serotonin/norepinephrine to strengthen descending pain inhibition.
Side effects: nausea, sleep change, dry mouth, sweating, raise BP slightly; avoid with severe liver disease.Gabapentin (α2δ calcium-channel ligand)
Dose: 300 mg at night → slowly to 300–600 mg three times daily (max commonly 3600 mg/day).
Purpose: first-line for many neuropathic pains.
Mechanism: reduces excitatory neurotransmitter release in overactive pain pathways.
Side effects: sleepiness, dizziness, swelling; reduce dose in kidney disease.Pregabalin (α2δ ligand)
Dose: 50 mg three times daily or 75 mg twice daily → up to 300–450 mg/day typical (max 600 mg/day).
Purpose: first-line; sometimes faster onset than gabapentin.
Mechanism & side effects: similar to gabapentin; may cause weight gain and edema.Amitriptyline (TCA)
Dose: 10 mg at bedtime → 25–75 mg at bedtime.
Purpose: first-line, especially if sleep is poor.
Mechanism: serotonin/norepinephrine reuptake block; sodium-channel effects.
Side effects: dry mouth, constipation, drowsiness; avoid in significant heart rhythm disease, glaucoma, BPH.Nortriptyline (TCA, less sedating/anticholinergic than amitriptyline)
Dose: 10 mg at bedtime → 25–75 mg at bedtime.
Purpose: alternative when amitriptyline is too sedating.
Side effects: similar but often milder; consider ECG in older adults.Venlafaxine XR (SNRI)
Dose: 75 mg daily → 150–225 mg daily.
Purpose: option if duloxetine not tolerated/ineffective.
Side effects: nausea, sweating, BP rise at higher doses; taper slowly to avoid withdrawal.Topical Lidocaine 5% patch (local anesthetic)
Dose: apply up to 12 hours/day to painful area (max number of patches per label); avoid broken skin.

Purpose: short-term second-line/bridge therapy when first-line agents fail or during flares.
Risks: nausea, dizziness, serotonin syndrome with SSRIs/SNRIs, seizure risk, dependence; use sparingly.
Dietary Molecular Supplements
(Evidence varies; use when deficiencies exist or as adjuncts. Discuss with your clinician, especially if pregnant, on blood thinners, or with kidney/liver disease.)
Alpha-lipoic acid (ALA) – 600 mg daily
Function/Mechanism: antioxidant that improves glucose metabolism; may reduce burning pain in diabetic neuropathy.Acetyl-L-carnitine (ALC) – 500–1000 mg two times daily
Mechanism: supports mitochondrial energy and nerve regeneration signals; studied in chemo-induced and diabetic neuropathy.Methylcobalamin (active B12) – 1000 mcg/day orally or as prescribed if deficient
Mechanism: rebuilds myelin and supports nerve DNA synthesis when B12 is low.Benfotiamine (fat-soluble B1) – 150–300 mg two times daily
Mechanism: reduces harmful glucose end-products (AGEs) relevant to diabetic nerves.Vitamin D3 – 1000–2000 IU/day (or per blood level)
Mechanism: immune and nerve function support; deficiency links to worse pain.Omega-3 fish oil (EPA+DHA) – 1–2 g/day
Mechanism: anti-inflammatory lipid mediators that can aid nerve repair.Magnesium (e.g., glycinate) – 200–400 mg elemental/day
Mechanism: NMDA receptor modulation; may reduce cramps and central sensitization.Curcumin (with piperine or optimized forms) – 500–1000 mg/day
Mechanism: anti-inflammatory signaling (NF-κB down-regulation); adjunct for pain.N-acetylcysteine (NAC) – 600–1200 mg/day
Mechanism: glutathione precursor; antioxidant/anti-inflammatory.Coenzyme Q10 (ubiquinone/ubiquinol) – 100–300 mg/day with fat
Mechanism: mitochondrial electron transport support; may help fatigue and nerve energy.
Important: Avoid excess vitamin B6 (pyridoxine)—doses above ~100 mg/day long-term can cause neuropathy. Keep multivitamin B6 modest unless your clinician prescribes otherwise.
Regenerative-Type Drugs
(These are not for routine painful neuropathy but for specific immune causes. Serious risks require neurologist oversight.)
IVIG (intravenous immunoglobulin)
Dose: common induction 2 g/kg divided over 2–5 days; maintenance varies (e.g., 0.4–1 g/kg every 2–4 weeks).
Function: modulates autoantibodies and immune cells to stop demyelination.
Mechanism: Fc-receptor blockade, anti-idiotype effects, complement inhibition.
Risks: headache, clot risk, kidney strain (choose low-osmolar products), aseptic meningitis.Prednisone / high-dose corticosteroids
Dose: ~0.5–1 mg/kg/day then slow taper based on response.
Function: rapid immune damping in CIDP, vasculitic neuropathy.
Mechanism: broad anti-inflammatory gene regulation.
Risks: glucose rise, weight gain, mood/sleep changes, bone loss, infection risk; use lowest effective dose.Rituximab (anti-CD20 monoclonal antibody)
Dose: 375 mg/m² weekly ×4 or 1000 mg ×2 two weeks apart; maintenance per specialist.
Function: for some antibody-mediated neuropathies (e.g., anti-MAG, cryoglobulinemic).
Mechanism: depletes B-cells producing pathogenic antibodies.
Risks: infusion reactions, infections (screen for hepatitis B).Azathioprine
Dose: ~1–2.5 mg/kg/day; check TPMT/NUDT15 activity before use.
Function: steroid-sparing immunosuppressant in chronic immune neuropathies.
Mechanism: purine synthesis blocker reducing lymphocyte proliferation.
Risks: bone-marrow suppression, liver toxicity; regular labs needed.Mycophenolate mofetil
Dose: 500 mg twice daily → 1000 mg twice daily as tolerated.
Function: alternative steroid-sparing agent.
Mechanism: inhibits inosine monophosphate dehydrogenase, limiting lymphocyte DNA synthesis.
Risks: GI upset, infections, teratogenic—contraception required.Cyclophosphamide (selected severe vasculitic cases)
Dose: oral ~1–2 mg/kg/day or IV pulses per protocol.
Function: strong immunosuppression to halt nerve-ischemia in vasculitis.
Mechanism: alkylates DNA of rapidly dividing immune cells.
Risks: marrow suppression, infertility risk, hemorrhagic cystitis; specialist use only.
Note on stem cells: hematopoietic stem cell transplant (HSCT) is investigational for refractory immune neuropathies and carries significant risks; outside clinical trials or highly selected centers it is not routine care. Be wary of commercial “stem cell” clinics making big promises without solid evidence.
Surgeries/Procedures
Carpal tunnel release (median nerve decompression)
Why: persistent numbness/weakness/thenar wasting from carpal tunnel after failed conservative care.
What happens: surgeon opens the ligament roof of the tunnel to relieve pressure on the nerve; often restores sensation and prevents further damage.Ulnar nerve decompression/transposition at elbow
Why: ulnar neuropathy (numb ring/little fingers, hand weakness).
What happens: frees the nerve or moves it to a safer path to stop chronic compression.Peripheral nerve repair/grafting/transfer (post-trauma)
Why: acute laceration or severe stretch injury.
What happens: ends are re-joined or bridged with graft; sometimes another nerve is transferred for function recovery.Spinal cord stimulation (SCS) implant
Why: severe chronic neuropathic pain refractory to medications (e.g., failed back surgery, CRPS, sometimes painful diabetic neuropathy).
What happens: a trial lead is placed; if relief is good, a permanent pulse generator is implanted to modulate pain signals.Dorsal root ganglion (DRG) stimulation
Why: very focal neuropathic pain (e.g., groin, foot).
What happens: targeted neurostimulation at the nerve-root ganglion gives precise pain control with less paresthesia spread.
Prevention Tips
Keep glucose in target if you have diabetes/prediabetes; small daily improvements pay off for nerves.
Daily foot checks and moisturize; treat calluses and tiny wounds early.
Choose protective shoes that fit well; use padded socks; avoid barefoot walking.
Don’t smoke; get help to quit—nerve blood flow improves quickly.
Limit alcohol to low-risk amounts or avoid if neuropathy is present.
Maintain B-vitamin sufficiency (especially B12); check levels after bariatric surgery or with vegan diets.
Review medication list for neurotoxic drugs with your clinician; ask about alternatives if needed.
Ergonomics: avoid sustained elbow/knee pressure; change positions; pad work surfaces.
Vaccinate against shingles if eligible to cut the risk of postherpetic neuralgia.
Stay active and strong—walk most days; add balance and strength sessions weekly.
When to See a Doctor
Sudden or rapidly worsening weakness, foot drop, or trouble using hands.
Severe back/neck pain with new weakness (possible root compression).
Autonomic red flags: fainting on standing, bowel/bladder paralysis, new erectile dysfunction.
Severe burning pain that ruins sleep or causes weight loss/mood crisis.
New numbness after a cut or deep wound (possible nerve laceration).
Foot ulcers, infections, or color change.
Unexplained neuropathy without a known cause—needs lab work.
Medication or supplement side effects (rash, swelling, confusion, falls).
Cancer patient on neurotoxic chemo developing numbness or pain—early dose adjustments help.
Any neuropathy with fever or systemic illness.
Food Rules: What to Eat & What to Avoid
Eat high-fiber, low-glycemic meals (vegetables, beans, whole grains) to steady blood sugar.
Eat omega-3-rich fish (salmon, sardines) 2–3×/week for anti-inflammation.
Eat B12 sources (eggs, dairy, fish, lean meats) or fortified plant foods if vegan.
Eat colorful plants (berries, leafy greens, peppers) for antioxidants that protect nerves.
Eat nuts/seeds (walnuts, chia, flax) for healthy fats and magnesium.
Avoid excess sugar and refined carbs (soda, sweets, white bread) that spike glucose.
Avoid heavy alcohol and avoid energy drinks—it worsens sleep and nerve pain.
Avoid trans fats and frequent deep-fried fast foods that raise inflammation.
Avoid mega-doses of vitamin B6 unless prescribed—too much can cause neuropathy.
Avoid very high-mercury fish (shark, swordfish); choose low-mercury options.
Frequently Asked Questions
1) Can neuropathy be reversed?
Sometimes. If the cause is fixed early—like correcting B12 deficiency, tight glucose control, or releasing a trapped nerve—nerves can heal slowly (months). Long-standing severe axonal loss is harder to reverse, but pain and function often improve with therapy.
2) How fast do nerves heal?
Axons regrow roughly 1–3 mm per day after repair if conditions are right. Sensation and strength can take months to return. Pain relief may come earlier with treatment.
3) Is all nerve pain the same?
No. Burning/electric pain (small-fiber) differs from deep numb/heavy feet (large-fiber). Matching treatment to the fiber type and cause works best.
4) What is the safest first medicine?
Guidelines commonly start with duloxetine, gabapentin/pregabalin, or a TCA. Choice depends on your health profile—e.g., duloxetine if depression/anxiety also present; gabapentin/pregabalin if sleep is poor; TCAs avoided when heart rhythm risk exists.
5) Do opioids help?
Opioids have modest short-term benefit but carry dependence and overdose risks. If used, keep doses low, short, and monitored. Many people improve without them.
6) What shoe is best for neuropathy?
Roomy toe box, soft insoles, firm heel counter, and no seams rubbing toes. Podiatrists can prescribe off-loading insoles if pressure points exist.
7) Can exercise make neuropathy worse?
Done right, exercise helps most people. Choose low-impact cardio, add strength and balance, and protect numb feet (inspect after sessions). Stop if new weakness or severe pain occurs and get checked.
8) Are supplements necessary?
They’re helpful when there’s a deficiency or specific goal (e.g., ALA for diabetic neuropathy). Food first; supplements are add-ons, not cures.
9) What’s small-fiber neuropathy?
Damage to tiny pain/temperature nerves. Standard nerve tests can be normal. Diagnosis often uses skin biopsy or autonomic testing.
10) Why are my symptoms worse at night?
Less distraction, cooler temps, and contact with sheets can amplify signals. Bedtime dosing (e.g., gabapentin/TCAs) and sheet/cradle tricks can help.
11) Can tight glucose control really change pain?
Yes—fewer spikes means less nerve stress and less inflammation over time. People often notice better energy and fewer flares with steadier numbers.
12) Is there a cure for chemotherapy-induced neuropathy?
There’s no guaranteed cure yet. Dose adjustment or switching chemo, plus exercise, ALC/ALA (discuss with oncologist), and pain-directed meds can help.
13) Should I worry about falls?
If vibration/position sense is poor, falls risk rises. Balance training, night lights, grab bars, and proper shoes make a big difference.
14) Are “stem cell shots” at private clinics legitimate?
Be cautious. Most are unproven for neuropathy and can be risky/expensive. Stick with regulated trials and specialist advice.
15) What’s the single best daily habit?
Walk most days, check your feet every night, and keep glucose and blood pressure in target. Those three protect nerves better than anything else.
