Secondary erythromelalgia

What it is

A rare neurologic disease characterized by intermittent pain, erythema, swelling, and heat of the extremities which is aggravated by warming and improved by cooling. Attacks can last between minutes and days and tend to be precipitated by heat, exercise, or physical dependence. The disease may be linked to a variety of underlying conditions including hematological, metabolic, connective tissue or neurological disorders, neoplasia, infections, and certain drug side effects, among others.

Disease

Prevalence figures describe populations, not individuals, and are often estimates from a single study. Where the figure is an incidence or a birth prevalence, it says so.

Signs and symptoms

These ranges are how often a sign appears across everyone diagnosed, not a prediction for one person — most people have some of these and not others. Orphanet also records findings that are specifically absent in this disease; those are in the data but not listed here.

ICD-10 codes

ICD-10 has no distinct code for most rare diseases, so many are filed under the nearest available one. A shared code identifies the group, not this disease — the ORPHAcode above is what identifies it.

Related health topics

Reached through the ICD-10 categories this disease is filed under, so these describe the broader group rather than this disease specifically.
