hi Monika, I went down the sinus road too because sometimes my pain/throbbing included my sinus area and upper-teeth and right between the eyes. Sometimes, too, my nose would be a little stuffy. It's so confusing but I have been told by 2 different Neuros that migraine mimics sinus. A test to do would be to lean over and see if it "hurts" your sinuses. If it does, tell your doctor, it could actually be sinus but more often than not, it is not sinus and migraine shouldn't cause post nasal drip which usually accompanies sinus. Take a triptan med and see if it alleviates your head pain. If it does, it is most like migraine. Hope you feel better.
DX: chronic migraine, cervical degeneration, depression/anxiety
RX: Wellbutrin, Lexapro, Soma, Immitrex
