Clinical Classification

Clinical Information

  • Erythromelalgia

    a peripheral arterial disease that is characterized by the triad of erythema, burning pain, and increased skin temperature of the extremities (or red, painful extremities). erythromelalgia may be classified as primary or idiopathic, familial or non-familial. secondary erythromelalgia is associated with other diseases, the most common being myeloproliferative disorders.
  • Erythromelalgia

    a rare disorder characterized by periodic inflammation and blockage of the vessels of the extremities, resulting in skin redness, swelling, and burning pain in the affected sites. it may manifest as a primary disorder caused by mutations of the scn9a gene or as a secondary disorder due to hematologic disorders or medication side effects.
  • Primary Erythermalgia|PERYTHM|Primary Erythromelalgia

    an autosomal dominant condition caused by mutation(s) in the scn9a gene, encoding sodium channel protein type 9 subunit alpha. it is characterized by episodes of recurrent warmth, redness, and burning sensations in the extremities.
  • Primary Erythromelalgia|PERYTHM|Primary Erythermalgia

    an autosomal dominant condition caused by mutation(s) in the scn9a gene, encoding sodium channel protein type 9 subunit alpha. it is characterized by episodes of recurrent warmth, redness, and burning sensations in the extremities.

Patient Education


Erythromelalgia

Erythromelalgia is a condition characterized by episodes of pain, redness, and swelling in various parts of the body, particularly the hands and feet. These episodes are usually triggered by increased body temperature, which may be caused by exercise or entering a warm room. Ingesting alcohol or spicy foods may also trigger an episode. Wearing warm socks, tight shoes, or gloves can cause a pain episode so debilitating that it can impede everyday activities such as wearing shoes and walking. Pain episodes can prevent an affected person from going to school or work regularly.

The signs and symptoms of erythromelalgia typically begin in childhood, although mildly affected individuals may have their first pain episode later in life. As individuals with erythromelalgia get older and the disease progresses, the hands and feet may be constantly red, and the affected areas can extend from the hands to the arms, shoulders, and face, and from the feet to the entire legs.

Erythromelalgia is often considered a form of peripheral neuropathy because it affects the peripheral nervous system, which connects the brain and spinal cord to muscles and to cells that detect sensations such as touch, smell, and pain.
