I'm wondering if i had a migraine headache, or something else yesterday.

Migraine: is a serious and complex neurologic disorder. Unilateral throbbing headache, dizziness, weakness, visual disturbances, blurry vision, nausea, sensitivity to light or sound, paresthesias and even partial blackout may be present during the episodes. The IHS offers specific diagnostic criteria for migraine headaches. See an orofacial pain or headache specialist.
