Anamnesis

A 48-year-old warehouse manager reports a severe headache that struck without any warning while he was lifting boxes at work. He says it was reaching its absolute worst within a few seconds of starting rather than building up gradually. He timed the episode and reports that it had settled by six minutes. He denies any preceding warning symptoms, fever, neck stiffness, or recent head trauma. There was no aura beforehand, and he has had no similar episodes before, feeling otherwise well once the pain passed.

Report this case — e.g. suspected re-identification risk.
