I have been having horrible headaches for about a month now they occur every day they do not go way. The headahces are behind my eyes and around my sinus area, I though I had a sinus infection went and had a ct scan my sinus's where clear. The Doctor said that I most likey had a frontal migraine and I should go see a nuero Dr which I have. He ordered a MRI which came back normal thank god. I'm now taking Topamax for my headaches which is not helping at all. I'm now up to a 100mg a day the only side effect i'm having is the tingling in im hands which is not bad. My other concerns is the lighted and dizzyness and nausea they will not go away, has any one else experienced this with there headaches? A good friend of mine that is a nurse believes that I might be experiencing cluster headaches. any ones thoughts would be helpful.
