Erythromelalgia is the name applied to the clinical syndrome of red, hot extremities. Most often, the feet are involved; less often the hands are also involved; rarely, the face (ears especially) may be involved. This short video describes what this syndrome is, what is known about why it happens, how it is diagnosed and managed. Here is a Mayo Clinic video about erythromelalgia:
Erythromelalgia is a rare disorder that is characterized by burning pain and warmth and redness of the extremities. There is primary (idiopathic) and secondary erythromelalgia (most commonly associated with myeloproliferative disorders).
The name is derived from 3 Greek words: erythros (“red”), melos (“limb”), and algos (“pain”).
