Most of us have suffered that blinding, nagging headache. Headaches are traditionally divided into two types: Tension headaches and Migraines. However, it is now believed that some headaches that were assumed to be falling into either of these categories are actually caused by damaged structures in the neck or cervical spine. Not all headaches, but quite a significant number of them seem to be originating in the neck. These headaches are called cervicogenic headaches.
