I get very frequent headaches and migraines and I know how you feel. I was hit by a car about 11 years ago and thats when my headaches/migraines began(but have become more intense through the years). I have had three cat scans and was taking Relpax,Inderal and Esgic for about a year before I got pregnant this past summer. Now I take nothing for the safety of my baby,but it's hard I get a migraine about every ten days or so and it lasts at least 24 hrs. I wish I had answers that would make us both better,but I dont. But,I wanted you to know I understand.
