Tension-type headache is probably the second most common headache type after migraine. They are often referred to as "hatband" headaches because they typically painful around the back of the head, the temples and forehead, as if a tight hat were in place. They tend to be pressure-like at onset and can last from hours to days. Tension-type headaches can co-exist with migraine, and one can transform or trigger the other. Tension-type headache is often responsive to physical therapy, relaxation therapy and anti-inflammatories or muscle relaxants. It is a myth that tension-type headaches are less painful or less disabling than migraines.
