2.1 Infrequent episodic tension-type headache

A 27-year-old delivery cyclist describes a headache attack he describes as typical of what he has experienced on and off for years. his headache days are uncommon, well under one a month when he looks back over his diary. The pain affects both sides of his head equally rather than being one-sided rather than being one-sided. Tonight's episode had already lasted about four hours on arrival and settled fully within the department a couple of hours later. He describes it as a dull, squeezing pressure rather than a throbbing beat. He mentions mild sensitivity to light tonight but no bother from the department noise, which he says is typical. He has not felt sick and did not vomit at any stage. He estimates this is at least his thirteenth such episode since he first noticed the pattern in his early twenties.
