Niki,
I generally agree with all the previous posters but ... My post-AN headaches ( only after the first surgery) were not caused by any foods but the surgery itself, however, I knew that large amounts of fried foods and some aged cheeses as well as salami would cause a migraine in me even before AN surgery (and now, too). That ruled out many common foods, including French Fries, salami on sandwiches and pizza, fried chicken, etc. However, I could still eat these in small amounts, especially infrequently. With post-surgery headaches, I discovered, I had absolutely no tolerance for these foods whatsoever. In fact, I could not even smell them because they made my headache worse. Moreover, if I ate these foods even in small amounts, that would set off a really persistent and strong headache. I was constantly in pain and did not want add to the load, so I ate only raw and boiled foods.
My point is that you might want to try to figure out which foods would give you a headache and try to avoid them. You might experience an overall reduction in headaches and a decreased need for medication.
Congratulations on your face! I saw this in another post.
Take care,
Eve
