Tension Type Headache
Introduction
Tension-type headache causes mild generalized pain (usually viselike) without the incapacity, nausea, or photophobia associated with migraine. (See also Approach to the Patient With Headache .) Tension-type headaches may be episodic or chronic: Episodic tension-type headachesoccur < 15 days/month. Episodic tension-type headache is very common; most patients obtain relief with over-the-counter (OTC) analgesics and do not seek medical attention. Chronic tension-type headachesoccur ≥ 15 days/month.
