I received a zero percent rating for migraines that have afflicted me for the past two years on a two to three times a week basis. I have visual changes and cannot speak or do anything but lay down. I had mris and everything done and was prescribed meds by the neurologist. The side effects freaked me out so i stuck w ibuprofen because the 800s worked. Now im hearing because im not taking the prescribed meds i dont get a percentage? Is this right?
