What Is Erythromelalgia?

Erythromelalgia is a rare condition that causes intense burning pain, redness, and swelling in the hands and feet. It can be triggered by heat, exercise, or stress, and can be debilitating.

Symptoms of erythromelalgia include:

* Intense burning pain in the hands and feet

* Redness and swelling in the affected areas

* Warmth to the touch

* Throbbing or pulsating sensation

* Skin that feels tight or shiny

Erythromelalgia can be caused by a variety of factors including:

* Primary erythromelalgia is a rare, genetic condition that is caused by a mutation in the SCN9A gene. This gene encodes a protein that is involved in the regulation of blood flow.

* Secondary erythromelalgia is caused by an underlying medical condition, such as:

* Myeloproliferative disorders, such as polycythemia vera and essential thrombocythemia

* Peripheral neuropathy

* Vasculitis

* Connective tissue disorders

* Medications, such as chemotherapy drugs and niacin

Diagnosis of erythromelalgia is based on the patient's symptoms and a physical examination. The doctor may also order tests to rule out other conditions that can cause similar symptoms.

Treatment of erythromelalgia is aimed at relieving the pain and preventing complications. Treatment may include:

* Cooling measures, such as ice packs, cold water immersion, and air conditioning

* Elevation of the affected limbs

* Compression stockings

* Nonsteroidal anti-inflammatory drugs (NSAIDs)

* Calcium channel blockers

* Opioid pain relievers

* Surgery may be necessary in severe cases

Erythromelalgia can be a debilitating condition, but it can be managed with proper treatment.
