Attacks of skin redness and burning sensation or pain in one or both external ears are the only common symptom.[1] Pain is often most pronounced at the ear lobe, and sometimes radiates to the jawbone and cheek.[1] The pain is normally mild, but has occasionally been described as severe.[1] The attacks can last seconds or hours, with 30 minutes to an hour being typical.[1] Most patients have daily attacks, ranging from 20 a day to a few a year.[1]
