Red ear syndrome is a rare disorder of unknown etiology which was originally described in 1994. It typically involves pain in and around the ear including the pinna and associated autonomic phenomena. The most significant symptom of Red ear syndrome of is cutaneous erythema of the ear ipsilateral to the pain. It is believed this syndrome may represent an auriculo-autonomic cephalgia and/or be part of the group of disorders known as trigeminal autonomic cephalgias which includes cluster headaches.[1][1][2]
