Keep getting a sharp, sick headache in one spot in my forehead. had mri in may for different reason, normal except pineal cyst. can regular headaches or migraines focus on one spot like that?

Tension headache : It frequently gives a discrete tender spot. Put a dollop of aspercrem right where it hurts. If you were much older i would check for temporal arteritis, an inflammation of the temporal artery.

Yes: Sharp, pain in one location can occur in migraine headaches and if of short duration, then they are referred to as "ice pick" headaches.
