CHRONIC TENSION HEADACHE : Primary headache constitute a major health problem. Population- based studies suggest 1- year prevalence rate of 38.3% for Episodic Tension Type Headache (ETTH) and 2.2% for the chronic form. “Normal” headaches are also known as Tension headaches. This is a lasting pain that can be felt in the head. Tension headaches are occasional although they can last half an hour to a week.

CAUSES : The etiology of tension type headache is unclear, but there is evidence to suggest that some forms may originate from sustained isometric contraction of muscles associated with the head and neck. This type of extended muscle contraction may result in local nutrient deficiencies due to ischemia which can generate trigger points within muscles. The tightly contracted region of a muscle trigger point can remain contracted for an extended period of time even without sympathetic activation. Collectively, these effects may result in a tension headache. The activation of myofascial trigger point has also been implicated as a cause of headache.
