Chronic headaches (headaches that occur on 15 or more days a month for at least 3 monhts) affect many people, but we have very little information on how to support people to manage their chronic headaches better and help them to make the best use of avalible drugs. CHESS is a randomised controlled trial which is comparing a headache education and self-management programme with usual GP care plus a relaxation CD. The results of the study will be used to help patients with chronic headaches in the future.

Primary outcome:
