The clinical symptoms include redness, heat, pain, and swelling. Typically, it affects both sides of the body, it may sometimes be unilateral. The primary form is present when the manifestations are not associated with an organic disease and it is usually called “erythermalgia” because of the significance of the heat felt in the extremities involved. The secondary or acquired form is related to underlying medical conditions. The clinical hallmarks include triggering or worsening of symptoms with exposure to heat or exercise and relief with cooling. The semantic of the word refers to the prefix “erythro-” that means redness, “mel-” indicates the limbs, and the suffix “-algia” refers to the associated pain.
