The most important clinical decision with Erythromelalgia Foot isn’t which treatment to start with — it’s identifying the correct subtype. That changes everything. Call (810) 206-1402.
Erythromelalgia Foot: Quick Answer
Erythromelalgia is a rare but distinctive condition causing intense burning, redness, and warmth in the feet (and sometimes hands). Often misdiagnosed for years. We have evaluated multiple cases at Balance Foot and Ankle. Here is the comprehensive erythromelalgia guide.
What Is Erythromelalgia
Erythromelalgia (EM): Rare disorder characterized by episodes of intense burning, redness, and increased temperature in extremities (most commonly feet). Hallmark triad: 1. Burning pain. 2. Redness (erythema). 3. Increased warmth. Episodes triggered by: Heat, exercise, certain foods/medications, dependent positioning. Relief: Cooling. Prevalence: Estimated 1.3 per 100,000 – quite rare.
Primary vs Secondary Erythromelalgia
Primary EM (idiopathic): No underlying cause identified; often genetic (SCN9A mutations); typically childhood/young adult onset; both feet usually affected. Secondary EM: Associated with: myeloproliferative disorders (especially polycythemia vera, essential thrombocythemia); autoimmune diseases; medications (calcium channel blockers, others); paraneoplastic syndromes; HIV; mercury poisoning. Workup: should investigate for underlying causes – especially myeloproliferative disorders.
Symptoms and Episodes
Episode characteristics: Sudden onset; intense burning (often described as “feet on fire”); marked redness; warmth on touch; can affect feet, hands, sometimes face/ears. Triggers: Heat exposure (warm rooms, hot showers, summer weather); exercise; dependent positioning (standing); certain foods (alcohol, spicy food); stress; certain medications. Relief mechanisms: Cooling (cold water, fans); elevation; cool environment. Many patients sleep with feet outside covers, in front of fans, or in cold water containers.
Diagnosis
Clinical diagnosis: Based on history and physical exam. Documentation: Photographs during episodes (redness, warmth visible). Workup for secondary causes: CBC (rule out polycythemia, thrombocythemia); JAK2 mutation testing; autoimmune workup; medication review; genetic testing for primary EM (SCN9A). Often misdiagnosed: as neuropathy, complex regional pain syndrome, allergic reaction, atopic dermatitis. Patient diaries: triggers, frequency, severity helpful.
Treatment Approach
Step 1: Treat underlying cause if secondary EM (e.g., aspirin for polycythemia vera). Step 2: Cooling strategies (most effective initial intervention): cool foot baths; cooling pads; air conditioning; fans; cooling socks. Step 3: Medications: aspirin (especially helpful for myeloproliferative cause); gabapentin/pregabalin; sodium channel blockers (lidocaine, mexiletine); SSRIs/SNRIs; sometimes opioids in severe cases. Step 4: Topical treatments: lidocaine patches; capsaicin (paradoxical relief); ketamine compounds.
Lifestyle Management
Cooling strategies: Sleep with feet outside covers; cool bedroom; fans; ice packs; cooling socks/inserts; avoid hot showers/baths. Avoid triggers: Heat exposure; vigorous exercise (or modify); certain foods (alcohol, spicy); medications that worsen. Compression socks: paradoxically helpful in some patients. Footwear: Open-toe options often preferred; breathable materials; avoid thick socks/insulated shoes.
Complications
Cooling complications: Many patients use ice/cold water excessively, leading to: macerated skin; frostbite injuries; trophic skin changes; permanent skin damage; infections from constant cold water immersion. Quality of life: Significant impact – sleep disruption, mobility limitations, depression common. Cardiovascular risk: Some EM patients have increased cardiovascular risk depending on underlying cause.
Prognosis
Variable course: Some patients have mild intermittent symptoms; others severely affected. Primary EM: Often lifelong with progression possible. Secondary EM: May resolve with treatment of underlying condition. Quality of life: Significant impact in many patients – affects sleep, mobility, work, social functioning. Multidisciplinary care: often optimal – podiatry, hematology (if myeloproliferative), neurology, pain management.
When to See a Podiatrist
See us if: suspected erythromelalgia (intense burning + redness + warmth episodes); previous EM diagnosis with foot complications; cooling-induced skin damage; need for podiatric management of EM; secondary infections from constant cooling; need referral to hematology/neurology for evaluation.

Frequently Asked Questions About Erythromelalgia Foot
What is erythromelalgia of the foot?
Rare disorder causing episodes of intense burning, redness, and increased warmth in the feet. Episodes triggered by heat, exercise, dependent positioning. Relieved by cooling. Estimated prevalence 1.3 per 100,000.
What causes erythromelalgia?
Primary (idiopathic): often genetic (SCN9A mutations). Secondary: myeloproliferative disorders (polycythemia vera, essential thrombocythemia); autoimmune diseases; medications; paraneoplastic syndromes. Important to investigate underlying causes.
How is erythromelalgia diagnosed?
Clinical diagnosis based on history and physical exam. Documentation: photographs during episodes (redness, warmth visible). Workup for secondary causes: CBC, JAK2 testing, autoimmune workup, medication review, genetic testing for primary EM.
How do you treat erythromelalgia?
Treat underlying cause if secondary. Cooling strategies (cool baths, fans, AC). Medications: aspirin (especially for myeloproliferative cause), gabapentin/pregabalin, sodium channel blockers, SSRIs/SNRIs. Topical: lidocaine, capsaicin.
Can excessive cooling cause complications?
YES – many patients use ice/cold water excessively, leading to: macerated skin; frostbite injuries; trophic skin changes; permanent skin damage; infections from constant cold water immersion. Important to balance symptom relief and skin health.
Is erythromelalgia a lifelong condition?
Variable. Primary EM: often lifelong with progression possible. Secondary EM: may resolve with treatment of underlying condition. Significant quality of life impact in many patients – multidisciplinary care often optimal.
When should I see a podiatrist about erythromelalgia?
Suspected EM (intense burning + redness + warmth episodes); previous EM diagnosis with foot complications; cooling-induced skin damage; need podiatric management; secondary infections; need referral to hematology/neurology for evaluation.
