Tension headache is one of the most common forms of headaches and it can occur at any age. It is pain or discomfort in the head, scalp, or neck, usually associated with muscle tightness in these areas.
These headaches may occur only occasionally in response to a stressful event, but may also be chronic, occurring frequently. Some tension headaches are nearly constant, with daily pain that may vary in intensity. It was renamed as Tension Type Headaches by the International Headache Society.
