2.4.1 Probable infrequent episodic tension-type headache

A 34-year-old delivery driver reports the fourth headache attack he has had in recent months. He explains that on a headache day such as this, the pain grips both sides of his skull, lasting anywhere from twenty minutes to a couple of days on each occasion, and is described as a steady, vice-like pressure with no pulsing element. On a 0–10 scale he put it at a moderate 4, never reaching a severe level. Walking around the department and moving about did not make it any worse. He noted mild light sensitivity but was not troubled by the ambient noise of the waiting room. He denied nausea and had not vomited. He estimated, when questioned, that this sort of headache tends to occur about twice a month during a bad patch.
