Hi, I have had migraines since I was 12 and I got them a few times a year. The typical Aura was blindess in one eye and then the zig zag lines and then the headach. The last few years I have been getting this feeling of its like your lights blink real quick. Kind of like when your AC or Refrigerator kicks on and your lights dim real quick. I get the feeling on and off througout the day and then the headach comes on. The Drs said definatly migraines but I have never had that kind of Aura before. Has anyone else had this Aura? Thanks Mindy
