The clinical definition of carotidynia is not a controversial one, whereas how its etiology should be interpreted is still uncertain. The study of the clinical features and the therapeutical results in 12 patients suffering from carotidynia reveals a marked resemblance to migraine. In particular, the case history reported points out a significant incidence of migraine as a familial disease, its special localization and the type of pain, the possible presence of a prodromal stage and the favourable response to the drugs that are known to be effective in migraine treatment. The theory that carotidynia should be ascribed to the group of vascular headaches is therefore suggested.
