Just be happy it's only a headache. For me it started out Monday with headache then went to swelling up an then more an then some more then I went to doc, got me a severe sinus infection that has went into my top teeth. So I'm on antibiotics now. Can't eat anything except chicken noodle soup and pudding. My face is so swollen that it looks like someone used it like punching bag. I told hubby that I refuse to anywhere in public looking like this.. Don't want anyone talking.. U no how small towns are. Lol I just can't wait till I can eat REAL food again. This antibiotic has got to get on the ball! But seriously if ur head been hurting that long, it might be sinus's. Try some Tylenol sinus. It might work.
