2.2.1 Frequent episodic tension-type headache associated with pericranial tenderness

A 44-year-old woman reports a long-standing pattern of headaches that has recurred over the years, representing at least her eleventh such episode. This episode has persisted for about four months, with headache days on around twelve occasions most months, amounting to roughly 178 headache days when totalled over the last year. The headaches have a tight, constricting quality and generally last somewhere between forty minutes and a few days. She finds that her rehabilitation exercises and general mobility do not make the pain worse. She denies any noticeable sensitivity to light or sound during these episodes. There has been no vomiting, and no nausea, throughout. She adds that firm pressure over her scalp and neck muscles produced tenderness on both sides when pressed.
