2.3.1 Chronic tension-type headache associated with pericranial tenderness

A man reports a headache that, by his account, has been with him on more days than not for a good while. He describes each spell as capable of running on for several hours, and occasionally it barely lets up for a full day before easing; exertion, including his daily walks with the dog, does not seem to alter it either way. He describes the pain as a constant tight band around the head rather than a throbbing sensation, and notices tenderness throughout when he presses on his own scalp, temples and neck muscles. He has not had nausea, mild or severe, has not vomited during any episode, and does not report sensitivity to light or noise. He estimates roughly 15 days a month with headache, and by his reckoning this has continued largely unchanged for about four months.
