Severe temple, headache, pain in left eye, migraine?

Migraine or glaucoma: This could be migraine particularly if you have the classic symptoms of an expanding circle of light that progresses to a zig zag pattern that precede it. Alternatively it could be the first symptom of glaucoma or a sinus infection. I would advise you to see an eyemd followed by an ENT doctor.

Possibly.: As always, making a diagnosis is the first step. Your physician should be able to take a history and examine you to decide if this is likely to be a migraine or something more significant like temporal arteritis or elevated intraocular/intracranial pressure. Headaches are common, migraines are less common and everything else is rare but all require evaluation.
