Allergy Testing For Migraines What Should I Do?(migraines)?

What should I do?(migraines)? - allergy testing for migraines

I am 16 years old and when I was younger, I got tested for the treatment of allergies and I am allergic to many things .. I used to have migraines all the time I had a scan to check for tumors in the brain. I clearly went. I wear glasses, but I still have a lot of headaches. If I feel I get vertigo, dizziness and sometimes vomiting. One night I woke with a headache so bad that I did not know what to do. My family has a history of high blood pressure and blood sugar problems, so I'm not sure if it has something to do with it. Suggestions?

Thank you --
