If you are experiencing severe headaches, see your medical professional. To help shed some light on the subject for some, I will mention my experience. Years ago, I started having a severe pain in the forehead over the left eye. This did not happen every day, but every once in a while, and I had to retreat to bed in a darkened room until the pain subsided many hours later. I did get medication from my family doctor for the pain, but the cause took research and personal experimentation. Eventually, through an elimination diet (eating a basic, bland diet), I found that my migraines were due to food sensitivities. I found that when I "overdosed" (ate too much of) certain foods--mostly grains (with or without gluten), I came down with a migraine headache the next day. The solution for me was to limit the amount of grain and also to rotate the grains, so that I would not eat any one of them but every four days. So today I would have rice, for instance, tomorrow corn, then wheat, then oats/rye, and so on. Barley can be coupled with any other grain, for me, but not two days in a row. This plan has largely solved my migraine problem, except when I accidentally "overdose" on a grain--too many cookies; wheat pasta for lunch and a pizza later; etc. I also sometimes get a migraine now due to severe lower back arthritic pain that seems to affect joints and the head eventually. But I mainly wanted to briefly offer up the food angle to those suffering from migraines and have not made the possible connection to food, knowing that each case would be unique.
