Headaches were actually my only real AN symptom.. well, after it was diagnosed we noticed "hey, my face is a little droopy on that side and I am a little dizzy", but before that I had near daily headaches for months. I was told that my headaches were AN related, because it was pushing on my brainstem. I had migraines years ago, and they weren't as bad as those, but no where near comfortable, either. Tylenol and caffeine (yey Coke!) helped some. Now, 15 weeks postop, the headaches are still there but at this point I just kind of tough it out. Last time I was at the dr's they said it was normal to still have headaches at that point (6 weeks postop). And, before surgery, my surgeon said I had a 1:3 chance of chronic migraines. Woohoo.
