I used to have really bad headaches it seemed like every week or two for years. I don't know if they were considered migraines but all I wanted to do was sleep because my head felt like it was going to explode and I could feel the muscles in my eyes ache if I would move them. Sometimes I would wake up with a headache.
Anyway I also used to take Excedrin all the time...probably a bottle every couple of months. Eventually I found out I have borderline high blood pressure. If I don't watch my salt intake, I will have a pounding headache and usually my blood pressure will be around 160/98.
