Quick answer: Burning feet syndrome (Grierson-Gopalan syndrome) is a symptom, not a diagnosis — the burning, heat, and night-time tingling almost always trace to a nerve or metabolic cause: most often peripheral neuropathy from diabetes, a B-vitamin deficiency, tarsal tunnel compression, or small-fiber neuropathy. See a podiatrist if it’s persistent, worsening, or comes with numbness, because treatment depends entirely on the underlying cause.
Waking up at 2 AM with your feet feeling like they are on fire — the soles burning, sometimes tingling, sometimes throbbing — is one of the most miserable and underdiagnosed experiences in medicine. Patients often suffer for years attributing it to “bad circulation” or “tired feet,” when in fact there is almost always a specific, diagnosable, and often treatable cause. In our Howell and Bloomfield Hills clinics, a systematic workup identifies the culprit in the vast majority of patients with chronic burning feet.
Burning feet that won’t quit? Persistent burning deserves a proper workup. A foot & ankle specialist can pinpoint the cause — neuropathy, a vitamin deficiency, or circulation — and start the right treatment. Balance Foot & Ankle offers same-week visits in Howell and Bloomfield Hills, MI.
The most important clinical decision with Grierson Gopalan Syndrome isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
What Is Burning Feet Syndrome?
Burning feet syndrome — formally called Grierson-Gopalan syndrome after the physicians who first described it — refers to a constellation of symptoms: persistent burning, heat, and sometimes tingling or aching in the feet, characteristically worse at night and partially relieved by cool surfaces or cold water. It is not a single disease but a clinical syndrome that can result from numerous underlying pathologies affecting the peripheral nerves of the feet.
The burning sensation reflects abnormal electrical activity in damaged, compressed, or inflamed nerve fibers — a phenomenon called ectopic discharge. Normal nerve fibers conduct impulses only when stimulated by an appropriate stimulus. Damaged nerve fibers fire spontaneously and excessively, generating the constant burning sensation even in the absence of any actual heat or injury. This is neuropathic pain — pain generated by the nervous system itself rather than by tissue damage.
Key takeaway: Burning feet that are worst at night and affect both feet simultaneously are the hallmark of length-dependent peripheral neuropathy — the longest nerves in the body (those supplying the feet) are affected first and most severely. The bilateral symmetric pattern, combined with the nocturnal worsening (less competing sensory input at rest), is highly characteristic. Single-foot burning or asymmetric distribution points toward a local compression cause like tarsal tunnel syndrome.
Cause 1: Peripheral Neuropathy — Diabetic and Otherwise
Diabetic peripheral neuropathy is the single most common cause of burning feet syndrome worldwide, affecting 50% of people with diabetes after 10+ years of disease. Chronic hyperglycemia damages the small blood vessels supplying peripheral nerves (vasa nervorum), creating ischemic nerve injury that begins in the longest nerves first — those reaching the toes — and gradually spreads proximally in a “stocking-glove” distribution.
The burning in diabetic neuropathy is characteristically bilateral, symmetric, begins at the toes and ball of foot, and is worst at night when activity-generated sensory input stops competing with the pain signal. It may be accompanied by numbness (sensory loss) — the paradox of painful-yet-numb feet that patients find confusing but that reflects simultaneous loss of protective sensation and gain of abnormal pain firing.
The only disease-modifying treatment for diabetic neuropathy is glycemic control — tight A1c management slows progression and in early stages allows partial nerve recovery. Symptomatic treatments (gabapentin, pregabalin, duloxetine, tricyclics) improve quality of life but do not affect the underlying nerve damage. In our diabetic population, we also focus intensively on foot protection: appropriate diabetic footwear, regular monofilament testing, and patient education to prevent the ulcers and infections that a numb, burning foot is susceptible to.
Key takeaway: Vitamin B12 deficiency is one of the most treatable and most commonly missed causes of burning feet. It is particularly prevalent in patients taking metformin (which blocks B12 absorption), vegetarians and vegans, patients with atrophic gastritis or prior gastric surgery, and older adults with reduced intrinsic factor production. A simple serum B12 and methylmalonic acid level confirms the diagnosis — and supplementation reverses the neuropathy if caught before permanent nerve damage occurs.
Cause 2: Vitamin Deficiency Neuropathy
Vitamin B12 deficiency causes burning feet by demyelinating the peripheral nerves — B12 is essential for myelin synthesis (the protective sheath around nerve fibers), and deficiency leads to progressive nerve dysfunction. The burning feet presentation is indistinguishable from diabetic neuropathy, which is why all patients presenting with burning feet should have B12 levels checked, regardless of diabetes status.
Critical subgroups at high B12 deficiency risk: patients on metformin (the most prescribed diabetes drug, which blocks B12 absorption in the gut — up to 30% of long-term metformin users become B12 deficient); vegetarians and vegans; patients with autoimmune gastritis or pernicious anemia; post-bariatric surgery patients; older adults with reduced gastric acid production.
B12 replacement (oral cyanocobalamin 1,000 mcg daily for deficiency without neurological symptoms; intramuscular B12 for confirmed neurological involvement) reverses the neuropathy if started before permanent axonal damage occurs. This is one of the most satisfying diagnoses to make — a fully reversible cause of burning feet that a simple blood test identifies.
Vitamin B1 (thiamine) deficiency — associated with chronic alcohol use, malnutrition, bariatric surgery, and prolonged IV nutrition — also produces burning, aching foot pain (part of “burning feet” syndrome originally described in malnourished populations). Thiamine replacement is the treatment.
Cause 3: Tarsal Tunnel Syndrome
Tarsal tunnel syndrome is compression of the posterior tibial nerve (or its branches) as it passes through the tarsal tunnel — the fibro-osseous canal behind the medial ankle. Unlike diffuse peripheral neuropathy, tarsal tunnel syndrome produces unilateral burning, tingling, and numbness across the sole and toes that radiates from behind the ankle. It is the foot’s equivalent of carpal tunnel syndrome.
Tinel’s sign (reproduction of the burning/tingling by tapping over the tarsal tunnel) is the most useful clinical test. Nerve conduction studies can confirm the diagnosis, though they are not always positive in early or mild compression. Overpronation and flat feet are major risk factors by stretching the tibial nerve as the arch collapses. Treatment: custom orthotics to control pronation, night splints, corticosteroid injection, and surgical decompression for confirmed cases failing conservative care.
Cause 4: Small Fiber Neuropathy
Key takeaway: Small fiber neuropathy (SFN) is a distinct condition that affects only the small unmyelinated C-fibers responsible for pain and temperature sensation — leaving the large fibers (responsible for vibration, proprioception, and nerve conduction velocity) completely intact. This means standard nerve conduction velocity (NCV) testing is normal in SFN. The diagnosis requires skin punch biopsy with intraepidermal nerve fiber density counting — a test many patients with burning feet never receive.
Small fiber neuropathy produces intense burning foot pain — often with allodynia (normal skin touch feels painful) — with a completely normal standard neurological exam and normal nerve conduction studies. It is frequently dismissed as “anxiety” or “functional” because the standard workup is negative. The correct diagnostic test is skin punch biopsy of the distal leg, measuring intraepidermal nerve fiber density — a reduced density confirms SFN definitively.
Causes of small fiber neuropathy include idiopathic (30% of cases — no identifiable cause), diabetes and pre-diabetes (impaired glucose tolerance), autoimmune diseases (Sjogren’s syndrome, celiac disease, lupus), genetic causes (sodium channel gene mutations — SCN9A, SCN10A), and sarcoidosis. A systematic workup is warranted for all confirmed SFN cases.
Cause 5: Erythromelalgia
Erythromelalgia is a distinct and dramatic burning feet syndrome — episodic attacks of intense burning pain, redness, and warmth in the feet, triggered by warmth and relieved by cold. Patients characteristically sleep with feet uncovered, hold feet against cold floors, or immerse feet in ice water during attacks. The burning and redness are simultaneous hallmarks — distinguishing erythromelalgia from other burning feet causes where redness is absent.
Erythromelalgia can be primary (often a sodium channel gene mutation — SCN9A — with onset in adolescence or young adulthood) or secondary to myeloproliferative disorders, particularly polycythemia vera and essential thrombocythemia. Any patient with erythromelalgia requires a complete blood count to screen for underlying hematologic disease. Secondary erythromelalgia from polycythemia vera responds dramatically to low-dose aspirin — in some cases providing complete symptom relief.
Cause 6: Medication-Induced Neuropathy
A significant number of burning feet cases are iatrogenic — caused by medications. The most important drug classes to review in any burning feet workup:
- Chemotherapy agents: Taxanes (paclitaxel, docetaxel), platinum compounds (cisplatin, oxaliplatin), and vincristine produce chemotherapy-induced peripheral neuropathy (CIPN) in 30–40% of treated patients
- Fluoroquinolone antibiotics: Ciprofloxacin, levofloxacin — FDA black box warning for peripheral neuropathy that may be permanent
- Metronidazole: Prolonged use associated with peripheral neuropathy
- Statins: Rare but documented association with peripheral neuropathy in some patients
- Metformin: Indirectly via B12 depletion (see above)
- Amiodarone, isoniazid, thalidomide: Additional agents with established neuropathy risk
⚠️ Burning feet symptoms requiring urgent evaluation
- New or worsening burning feet in a diabetic patient — neuropathy progression, needs A1c optimization and ulcer risk assessment
- Burning feet with systemic symptoms: weight loss, fatigue, night sweats — possible malignancy or systemic disease
- Rapidly progressive bilateral burning with leg weakness — Guillain-Barré syndrome or other acute neuropathy, emergency evaluation
- Burning feet with episodes of red, hot, swollen feet relieved by cold — erythromelalgia, needs hematologic workup
- Burning feet plus balance problems or falls — large fiber neuropathy or CNS cause, neurology referral warranted
Diagnosis: The Workup We Run
Our standard evaluation for burning feet syndrome in the podiatric setting: detailed history (diabetes status, medications, alcohol use, diet, B12 risk factors, symptom distribution and timing); neurological examination (10-g monofilament, light touch, temperature, vibration, ankle reflexes); vascular assessment; and laboratory panel (fasting glucose and HbA1c, serum B12 and methylmalonic acid, CBC, comprehensive metabolic panel, TSH). For cases not explained by the initial workup, we refer to neurology for NCV/EMG and, when indicated, skin punch biopsy for small fiber neuropathy.
MOST COMMON MISTAKE WE SEE
Burning feet are almost universally attributed to “neuropathy” and treated with gabapentin — but neuropathy itself has multiple subtypes requiring different treatments. Prescribing a nerve-calming medication without identifying the root cause (diabetes, vitamin B12 deficiency, tarsal tunnel compression, small fiber neuropathy, or erythromelalgia) delays the correct intervention. The workup matters: HbA1c, B12, CBC, TSH, and nerve conduction studies together change the diagnosis in a significant percentage of burning feet cases.
DIFFERENTIAL DIAGNOSIS — CONDITIONS THAT CAUSE BURNING FEET
- Diabetic peripheral neuropathy — most common cause; symmetric stocking-glove distribution; diagnosed by HbA1c and nerve conduction studies
- Vitamin B12 deficiency neuropathy — burning/tingling that worsens at night; common in metformin users, vegans, and elderly patients; serum B12 is the test
- Tarsal tunnel syndrome — burning that is localized to the plantar foot; positive Tinel’s sign at the tarsal tunnel; NCV shows entrapment
- Small fiber neuropathy — burning without weakness or sensory loss on standard NCV; diagnosed by skin punch biopsy for intraepidermal nerve fiber density
- Erythromelalgia — burning with visible redness and warmth, triggered by heat or exercise, relieved by cold; can be primary or secondary (polycythemia vera, essential thrombocythemia)
- Medication-induced neuropathy — statins, metronidazole, isoniazid, chemotherapy agents; burning onset correlates with drug initiation
RED FLAGS — SEE A PODIATRIST OR NEUROLOGIST URGENTLY
- Burning feet with visible redness and skin color changes that fluctuate with temperature

Frequently Asked Questions
Why are my feet burning at night but not during the day? Neuropathic burning is amplified at night because the brain’s descending pain inhibition system is less active during quiet rest, and there is no competing sensory input from activity to dampen the pain signal. Additionally, peripheral blood flow patterns change with recumbency, altering the thermal environment at the nerve endings. Most neuropathic burning feet conditions follow this nocturnal pattern — it is the hallmark, not the exception.
Can burning feet be cured? It depends on the cause. B12 deficiency neuropathy caught before permanent axonal damage: yes, essentially curable with replacement. Tarsal tunnel syndrome: yes, with surgery or conservative care depending on severity. Diabetic neuropathy: not curable, but progression stops and symptoms may improve with excellent glycemic control. Small fiber neuropathy from treatable causes (celiac disease, Sjogren’s): partially reversible with disease treatment. Idiopathic SFN: managed rather than cured, with symptom control medications.
What is the best medication for burning feet? First-line medications with the strongest evidence: duloxetine (60–120mg daily — FDA-approved for diabetic peripheral neuropathic pain; also the first-line choice per ADA guidelines), gabapentin (300–1,200mg three times daily — widely used, generally well-tolerated), and pregabalin (75–150mg twice daily). Topical agents — capsaicin cream, lidocaine patches — are useful for localized pain without systemic side effects. None of these address the underlying cause.
The Bottom Line
Burning feet syndrome almost always has a diagnosable cause — and the workup to find it is straightforward. B12 deficiency, pre-diabetes, and tarsal tunnel syndrome are three common, treatable, and frequently missed causes that a simple blood draw and clinical exam can identify. If you have been told your burning feet are “just part of aging” or attributed to stress without a proper diagnostic evaluation, that evaluation is the most important next step.
Our Howell and Bloomfield Hills podiatric teams run a systematic burning feet workup at every relevant visit. For the subset of patients requiring neurology collaboration (skin biopsy for SFN, complex medication-induced neuropathy), we coordinate directly. Most patients leave their first evaluation with both a suspected diagnosis and a treatment plan.

What causes Grierson-Gopalan syndrome (burning feet)?
Grierson-Gopalan syndrome is caused by nutritional deficiencies (B vitamins, pantothenic acid), peripheral neuropathy from diabetes, thyroid disorders, or idiopathic nerve dysfunction. A podiatrist or neurologist can identify the underlying cause.
How is burning feet syndrome treated?
Treatment depends on the cause: vitamin B supplementation for deficiency, blood sugar control for diabetic neuropathy, cooling foot soaks, and appropriate footwear. Medications like gabapentin may help in severe nerve pain cases.
When should I see a podiatrist for burning feet?
See a podiatrist if burning feet persist more than 2 weeks, worsen at night, are accompanied by numbness or tingling, or if you have diabetes or another condition affecting circulation.

📋 Dr. Tom Biernacki, DPM, FACFAS answers:
Burning feet that worsen at night — classic Grierson-Gopalan syndrome — are most commonly caused by peripheral neuropathy from diabetes, vitamin B12 or B1 deficiency, or chronic alcohol use. Other causes include hypothyroidism, kidney disease, Charcot-Marie-Tooth disease, and tarsal tunnel syndrome. The burning sensation occurs because damaged nerves fire abnormally, especially without the competing sensations of daytime activity. First-line investigations: fasting glucose, HbA1c, B12, B1 (thiamine), TSH, and BMP. Treatment depends on the cause: B12 injections can dramatically improve deficiency-related burning; diabetic neuropathy management requires glucose control plus medications like gabapentin or duloxetine for symptom relief. Soaking in cool (not cold) water, elevating the feet, and avoiding alcohol temporarily reduce symptoms while the underlying cause is addressed.
