Quick Answer:
Quick Answer: Erythromelalgia is a rare condition characterized by episodic burning pain, redness, and warmth in the extremities — most commonly the feet. Episodes are triggered by warmth, exercise, and dependency (feet hanging down), and are relieved by cooling and elevation. Primary erythromelalgia is caused by gain-of-function mutations in SCN9A (encoding the Nav1.7 sodium channel in pain-sensing neurons), making this a true sodium channelopathy. Secondary erythromelalgia occurs in association with polycythemia vera, essential thrombocythemia, small fiber neuropathy, connective tissue diseases, and certain medications. Diagnosis is clinical but supported by objective testing including skin biopsy for intraepidermal nerve fiber density, autonomic testing, and complete blood count with differentials. Treatment is condition-specific: aspirin is dramatically effective for myeloproliferative disease-associated cases; sodium channel blockers (mexiletine, carbamazepine) target the channelopathy; SNRIs and gabapentinoids address neuropathic pain components.
Erythromelalgia — sometimes called erythermalgia or Mitchell’s disease — is a rare but profoundly disabling condition characterized by episodes of intense burning pain, erythema (redness), and elevated skin temperature in the feet and sometimes the hands. Patients often describe placing their feet in ice water, standing on cold tile floors, or sleeping with feet outside the covers as the only way to manage episodes. At Balance Foot & Ankle, Dr. Biernacki is experienced in evaluating burning foot conditions and coordinating the multidisciplinary workup required for complex presentations.
Primary vs. Secondary Erythromelalgia
Distinguishing primary from secondary erythromelalgia is the most important diagnostic step, as treatment differs completely. Primary (idiopathic) erythromelalgia includes both hereditary cases (autosomal dominant SCN9A mutation) and sporadic cases. The Nav1.7 sodium channel mutation causes hyperexcitability of peripheral pain-sensing (nociceptive) neurons — essentially, the pain-signaling system fires continuously and excessively in response to warmth. Secondary erythromelalgia arises from an underlying medical condition: myeloproliferative neoplasms (polycythemia vera, essential thrombocythemia) are the most important to identify because aspirin provides dramatic relief; small fiber neuropathy from diabetes, autoimmune conditions, or idiopathic causes; connective tissue diseases including lupus and rheumatoid arthritis; and medication-induced cases (calcium channel blockers, bromocriptine, verapamil).
Diagnostic Workup
Dr. Biernacki coordinates a targeted workup for erythromelalgia presentations. Laboratory panel: CBC with differential and peripheral smear (screening for polycythemia vera and essential thrombocythemia), JAK2 V617F mutation, metabolic panel, ANA, rheumatoid factor, ESR/CRP, fasting glucose and HbA1c. Skin punch biopsy: intraepidermal nerve fiber density (IENFD) assessment — the gold standard for diagnosing small fiber neuropathy, which is frequently the underlying condition. Autonomic testing: quantitative sudomotor axon reflex test (QSART) at specialized neurology centers. Genetic testing: SCN9A gene panel for suspected primary hereditary cases with family history. Referral to neurology, hematology, or rheumatology is coordinated based on diagnostic findings.
Treatment Approaches
Treatment is highly condition-specific. Myeloproliferative-associated: low-dose aspirin (81–325mg daily) produces dramatic, often complete symptom relief within days — this is one of medicine’s most elegant therapeutic responses. Cytoreduction with hydroxyurea for high-risk polycythemia vera/ET cases requires hematology co-management. Primary channelopathy (SCN9A): mexiletine (a sodium channel blocker) has shown efficacy in case series; carbamazepine/oxcarbazepine; topical sodium channel blockers (lidocaine). Neuropathic pain management: SNRIs (duloxetine, venlafaxine), gabapentinoids (pregabalin, gabapentin), and tricyclic antidepressants address the central sensitization component. Non-pharmacological: cooling fans, elevation, avoiding heat triggers, compression stockings (with caution — can worsen symptoms in some patients). Extremity cooling (not ice — frostbite risk is real) during episodes provides temporary relief.
Living with Erythromelalgia in Michigan
Michigan’s cold winters can actually provide environmental symptom relief for erythromelalgia patients during flares — though extreme cold carries frostbite risk in patients who habitually ice their feet. Summer heat and warm indoor environments are the most challenging seasons. Practical adaptations include breathable footwear (mesh uppers, open-toe sandals), cooling insoles, avoiding synthetic or wool socks, sleeping with a fan directed at the feet, and avoiding prolonged standing on warm surfaces. Dr. Biernacki helps patients develop personalized coping strategies alongside medical management to maintain quality of life.

Dr. Tom Biernacki’s Recommendation
Erythromelalgia is one of the most distressing conditions I encounter — patients describe their feet as being on fire constantly, and the desperation to cool them leads some to seriously dangerous icing habits that cause frostbite on top of everything else. My first job is always to rule out a myeloproliferative disorder — because if that’s the cause, a simple aspirin prescription can transform someone’s life within days. For the primary channelopathy cases, treatment is harder, and I work closely with neurology colleagues. But getting the right diagnosis first is everything. If you have burning, red, hot feet that cool water relieves — please come in for a proper evaluation.

Frequently Asked Questions
What’s the difference between erythromelalgia and regular burning feet?
Regular burning feet (often from peripheral neuropathy) produce constant symptoms without the characteristic episodic, warmth-triggered, visibly red and hot appearance of erythromelalgia. In erythromelalgia, feet visibly turn red and feel hot to the touch during episodes, and cooling provides rapid relief — this is the hallmark. Peripheral neuropathy burning is typically constant and less dramatically relieved by cooling.
Can erythromelalgia be cured?
For secondary erythromelalgia caused by polycythemia vera or essential thrombocythemia, treatment of the underlying condition (including aspirin therapy) often produces complete or near-complete remission. Primary channelopathy cases are typically chronic, requiring ongoing symptom management. Identifying and treating the underlying cause is the best path toward maximal relief.
Is it dangerous to cool my feet in ice water?
Yes — habitual icing of feet is a real danger in erythromelalgia. Prolonged exposure to cold, particularly ice water, can cause frostbite and paradoxical worsening of pain through cold-induced nerve damage. We recommend cool (not cold) water, cooling fans, and gel cooling pads as safer alternatives to ice water immersion.
What specialist should I see for erythromelalgia?
A podiatrist is an excellent first point of contact for foot-specific burning pain evaluation and can initiate the diagnostic workup. Depending on findings, referral to neurology (for channelopathy, small fiber neuropathy), hematology (for myeloproliferative disease), or rheumatology (for autoimmune causes) is coordinated. A team approach typically achieves the best outcomes.

When should I see a podiatrist?
If symptoms persist past 2 weeks, affect your normal activity, or are accompanied by red-flag symptoms (warmth, redness, swelling, inability to bear weight).
What does treatment cost?
Most diagnostic visits and conservative treatments are covered by Medicare and major insurers. Out-of-pocket costs vary by your specific plan.
How quickly can I get an appointment?
Most non-urgent cases see us within 5 business days. Urgent cases (sudden pain, possible fracture) typically same or next business day.
Foot pain typically responds best to early podiatrist evaluation, conservative treatments such as supportive footwear and targeted physical therapy, and—when needed—custom orthotics or in-office procedures. Most patients see meaningful improvement within 4-6 weeks of starting a structured treatment plan. Schedule an evaluation at our Howell or Bloomfield Hills office for a clinical assessment.
What is Foot pain?
Foot pain is a common foot/ankle condition that affects mobility and quality of life. Understanding the underlying cause is the first step in successful treatment. Our podiatrists at Balance Foot & Ankle perform a hands-on biomechanical exam, review your activity history, and use diagnostic imaging when appropriate to identify the root cause—not just treat the symptom. Many patients have been told to “rest and ice” without a deeper diagnostic workup; our approach is different.
Symptoms and warning signs
Common signs of foot pain include pain that worsens with activity, morning stiffness, swelling, tenderness when palpated, and difficulty bearing weight. If you experience sudden severe pain, inability to walk, visible deformity, numbness or color change, contact our office the same day or visit urgent care—these can signal a more serious injury such as a fracture, tendon rupture, or vascular compromise. Diabetics with any foot wound should seek same-day care.
Conservative treatment options
Most cases of foot pain respond to non-surgical care: structured rest, supportive footwear changes, custom orthotics, targeted stretching and strengthening protocols, anti-inflammatory medications when medically appropriate, and in-office procedures such as ultrasound-guided injections. We also offer advanced therapies including MLS laser therapy, EPAT/shockwave, regenerative injections, and image-guided procedures. Treatment is sequenced from least invasive to most invasive, and we explain the rationale at every step.
When is surgery considered?
Surgery is reserved for cases that fail 3-6 months of well-structured conservative care, when there is structural pathology (severe deformity, complete tear, advanced arthritis), or when imaging shows damage that will not heal without intervention. Our surgeons have performed 3,000+ foot and ankle procedures and prioritize minimally-invasive techniques whenever appropriate. We discuss recovery timelines, return-to-activity milestones, and realistic outcome expectations before any procedure is scheduled.
Recovery timeline and prevention
Recovery from foot pain varies based on severity and chosen treatment path. Conservative cases often improve within 4-8 weeks with consistent adherence to the protocol. Post-procedural recovery may range from a few days (in-office procedures) to several months (reconstructive surgery). Long-term prevention involves footwear assessment, activity modification, structured strengthening, and regular check-ins with your podiatrist if you have a history of recurrence. We provide written home-exercise plans and digital follow-up support.
