I have sort of been diagnosed with Silent Migraine, really I just get wicked dizzy and have nystagmus. It isn't vertigo, can't be brought on with position change. So I have been experiencing it for about 5 years, once or twice a week sometimes more and sometimes less. Ive had the Cardio tests, the Positional vertigo testing and been to a Neurologist and ENT. Have been put on Topiromate and it has lessened the occurrence but not the way I wanted to spend the rest of my life. Can't get too stressed, can't go to the gym and get over heated. I hate the nausea but i'm happy that I don't get the headache! Any one had any success getting rid of this?
