Erythromelalgia (ICD-10 I 73.8)

Definition

Erythroma algae are characterized by frequent episodes of burning pain and redness in the feet and / or hands. The reasons are several. Some have one gene mutation that affect ion channels (reference: Bennett DLH, Lancet Neurol, 2014). Changes in the small nerve fibers affect the circulation in small blood vessels.

Occurrence

About 1,3 new cases per 100.000 population per year (corresponds to 65 new cases per year in Norway). Erythromelalgia is thus defined as one rare disease.

Symptoms

Burning pain, episodes. Most often in both feet, but can also be on hands, ears and nose. Redness and swelling. Some have Raynaud's . Symptoms are alleviated by cooling.
