Erythromelalgia.

Erythromelalgia is an extraordinary disease which remains elusive in its pathophysiology and management. Victims suffer intense burning and redness of the hands and feet. In what appears to be the antithesis of Raynaud's disease, the pain is relieved by emersion in cold. A child with erythromelalgia is described whose symptoms began at age 3 years. Pharmacological management trials and thermography are incorporated in the report.
