2.2.2 Frequent episodic tension-type headache not associated with pericranial tenderness

A 41-year-old warehouse supervisor reports recurrent attacks of headache that have troubled him since around four months ago. He counts 179 such headache days over the past year, working out to roughly 13 headache days most months, and recalls at least ten distinct episodes over his lifetime that fit this pattern. Each episode affects both sides of the head and lasts anywhere from half an hour up to seven days if left untreated, carrying a pressing, band-like quality rated mild to moderate. He says the pain does not worsen with walking or lifting, and he denies any accompanying light or noise sensitivity. He adds that his scalp is non-tender to palpation and there is no nausea or vomiting with any episode.
