You are having: Episodes of migraine headaches, and it seems these are becoming quite frequent. Unlikely you have structural problems in brain or eye, but, if appropriate, your doctor might order MRI or cat. Best outcome if you start preventative approach, with topirimate, depakote, even beta blocker, but also, otc preps like riboflavin, co-q-10, butterbur. A triptan could abort the headache. See your doc.
