Nerve Pain (Neuropathy)
Burning, tingling, numbness, or shooting pain along nerve pathways. May result from diabetes, nutrient deficiencies (especially B12), or nerve damage.
TL;DR
Nerve pain (burning, tingling, electric shocks) signals nerve damage — from diabetes, B12 deficiency, alcohol, or chemotherapy most commonly. Alpha-lipoic acid has the best supplement evidence, particularly for diabetic neuropathy, and B12 works when deficiency is the cause. Standard painkillers barely touch it; finding the cause early matters because nerve damage can become permanent.
Overview
Burning, tingling, shooting pain, or numbness caused by damaged or irritated nerves — most commonly in the feet and hands from diabetes, B12 deficiency, or chemotherapy. Unlike ordinary pain, nerve pain responds poorly to standard painkillers, and the priority is always finding and treating the cause before the damage becomes permanent.
Root Causes
Evidence synthesis: Alpha-lipoic acid has the strongest supplement evidence for neuropathy, with multiple randomised trials (largely in diabetic neuropathy, including the SYDNEY and NATHAN trials) showing improved symptoms and nerve conduction — strongest with intravenous dosing, with oral forms showing more modest benefit. Vitamin B12 replacement clearly improves neuropathy when deficiency is the cause, and metformin users are a high-risk group. Acetyl-L-carnitine has moderate evidence in chemotherapy-induced and diabetic neuropathy. Prescription options (duloxetine, pregabalin, amitriptyline) have robust trial support for symptom control, while tight glucose control prevents progression in diabetes. Standard analgesics like ibuprofen and paracetamol are ineffective for neuropathic pain — a key patient-education point.
How It's Diagnosed
When to See a Doctor
Ask for assessment if numbness or burning is spreading, affects both feet symmetrically, or follows a new medication. Seek urgent care for rapidly ascending weakness over hours to days, loss of bladder or bowel control, or numbness around the groin.
Supplements Studied For This
PEA
Yes, as an adjunct for neuropathic pain. The effect size is clinically meaningful and the safety margin is unusually wide.
Alpha Lipoic Acid (ALA)
Alpha-lipoic acid has the best supplement evidence for neuropathy — multiple trials in diabetic nerve damage show symptom and nerve-conduction improvement — though the strongest results came from intravenous dosing, and treating the underlying cause remains essential.
