In a series of 81 patients with chronic cervicobrachialgia, 54 (67%) reported that they also suffered from recurrent headache. Forty-four (81%) of these patients were classified as having cervical headache, 5 as having migraine, 2 with tension-type headache, and 3 patients were not classifiable according to the diagnostic system of the International Headache Society (IHS). Patients with headache presented significantly higher tenderness scores and pain intensity in the neck-shoulder-arm region than patients without headaches. Twenty-three (52%) of the 44 patients with cervical headache reported that their headache had improved after treatments directed towards their cervicobrachialgia. The IHS classification system of cervical headache is discussed.
