Anamnesis

The patient, a 57-year-old librarian, reports a single episode of head pain that struck her without warning at the exact moment she strained hard during a bout of vomiting from a stomach bug. The pain reached its worst within seconds of the strain, rather than building up over minutes, and lasted around an hour before fully resolving. This has not recurred since, and she has no prior history of anything similar. She has felt well since the stomach bug resolved.

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