2.1 Infrequent episodic tension-type headache

A site foreman describes headache complaints, which he has carried for many years, which he has never before sought specialist advice about. His days with the problem are uncommon; his headache days are genuinely uncommon, no more than once every couple of months if he is honest with his diary, and this is at least the thirteenth such attack he has experienced since his thirties. The discomfort sits across the whole of his head, equally on both sides and typically runs its course over the best part of a day, several hours at least, before lifting entirely. He continues his usual duties throughout, and walking the site and using ladders without any increase in pain. He mentions no particular bother from light or sound during an attack, and there has been no nausea and and no vomiting on any occasion he can recall.
