Tension-type headaches.

Tension-type headaches are generally characterized by slowly progressive, dull, constant, nonpulsatile pain in the occipital and posterior neck or in a "headband" distribution. Episodic tension-type headaches occur fewer than 15 times a month, and chronic tension-type headaches occur more than 15 times a month for at least six months. Cranial radiography, computed tomographic scanning, electroencephalography and other adjunctive tests are unnecessary if the presentation is typical and the headache is not associated with seizure activity, mental status changes, neurologic deficits and other markers of potentially serious underlying disease. Treatment of episodic tension-type headaches may include topical heat or cold packs, exercise and other stress-reduction techniques, mild analgesics, muscle relaxants and trigger-point injections. Some patients may benefit from antidepressants and individual or family counseling.
