3.3.1.1 Episodic SUNCT

A 52-year-old theatre nurse describes longstanding short-lived head attacks confined to the right side of her head, severe in intensity, arriving as a rapid burst of repeated stabs rather than a single jolt, with pain that occasionally spreads down toward her jaw rather than staying near her eye. During an attack her right eye becomes bloodshot and streams, and she notices the pupil on that side narrowing compared to the other. Each attack is over within about two minutes. She currently counts two attacks a day and estimates at least 21 across the present run, which is her third such run of attacks since they began several years ago, each run lasting roughly a week before a long, symptom-free interval. She reports no aura, no vomiting, and no photophobia between episodes.
