Cervicogenic headache (CH) was only recently recognized by the International Headache Society as a distinct headache diagnosis. It is described as pain originating in the structures of the cervical spine and characterized as a deep, non-throbbing, recurring headache. Its prevalence has been estimated to be as high as 16% of the population.(1)
