Everything got blurry and looked like I was reading another language. had a bunch of tests at hosp. it was at first thought I had a mini stroke, but after all the tests were read the dr said I had a migraine something, (can t remember the second word.) on the top of my head. didn t feel pain just terrified that i couldn. t see. can you tell me what the migraine something is and what it is all about
