3.3.1.1 Episodic SUNCT

A 68-year-old retired bus conductor describes ongoing short-lived headache attacks over his right temple. The pain is moderate but insistent, arriving as a rapid series of stabs one after another rather than a single jab, always on the right. Each attack runs for around six and a half minutes. During an attack his right eye reddens, the eyelid on that side swells, and it waters heavily, settling back to normal soon afterwards. He is currently having five attacks a day, and he estimates close to forty attacks in this current bout. This is his sixth such bout over the years, and bouts like this have lasted about a week before settling into long symptom-free periods.
