Episode Synopsis


The cause of tension headaches is not clear. Experts believe there may be more than one factor that causes tension headaches. In the past, doctors believed that tension or spasms in the muscles of the neck, face, jaw, head, or scalp played a role. Now they think a change in brain chemicals may also contribute to tension headaches.
