A patient presents with localized pain below the right eye, photophobia, and throbbing discomfort. Episodes are recurrent and last several hours. Most likely diagnosis?

Correct answer: B. Migraine

• A. Maxillary sinusitis typically causes constant pressure-like pain associated with congestion/infection symptoms, not recurrent throbbing episodes with photophobia.
• B. Correct. Recurrent, throbbing, unilateral pain with photophobia lasting hours is the classic presentation of migraine headache.
• C. Acute angle-closure glaucoma causes severe eye pain with visual changes/halos and is typically a single acute event, not a pattern of recurring episodes.
• D. Trigeminal neuralgia produces brief, sharp, electric-shock-like pain triggered by light touch, not prolonged throbbing episodes with photophobia.

Note: C fibers transmit dull, aching, throbbing pain — relevant to migraine pathophysiology.
