Tension Headaches
Tension-type headache (TTH) is the most common headache. It typically produces a generalized mild to moderate pain all over the head. It can also cause pain in the back of the neck at the base of the skull. The actual cause of tension-type headaches is still up for debate. Muscle tension was one thought to be the main cause of this particular type of headache pain, but researchers are not convinced it's the only cause, hence the name "tension-type."
