Why do you get Migraines?

This blog is for all of you migraine sufferers out there. Hopefully it will help you discover what is causing your particular migraines.
When I was in about 7th or 8th grade, I started getting a lot of migraines. I couldn't do anything when I got these. Usually it would just hurt on one side of my head really bad. Sometimes I would throw up during these because it hurt so bad. As the problems persisted, my parents took me to a doctor to see what was wrong. First thing that they thought was wrong was my allergies. So they put me on some allergy medicine and sent me on my way. Well of course, the headaches continued, so we made our way back to the doctor's office. This time I found myself taking a bunch of test to try to find out what was wrong with my head. Safe to say that all of them turned up negative. So the doctor finally told me to start watching what I eat. Whenever I got a migraine, I would right down what I ate or drank in the past few hours. Come to find out that I was allergic to certain foods. Cheddar cheese was the main culprit (mainly because of my love for macoroni and cheese). The weird thing is that I can eat white cheese. But that cheddar puts me on my knees. The longer that I have kept up with what I eat when I get migraines, the more foods I find that I'm allergic to. Here are just a few that I have found: cheddar cheese, sweet tea, seasoning on fries, spaghetti sauce, milk, onion rings, and a few other things.
So if you are like me and get migraines a lot but can't figure out what is causing them, try watching what you eat. It might just keep you from a lot of miserable nights with all the lights turned off. This has been another random blog that will hopefully help some of you migraine sufferers out there.
