I have heard of those visual auras being a migraine without the headache...occular migraines. I haven't had them, so I am not so familiar with them. Sorry you are having them more frequently, is the Topamax/Topiramate helping? I always have headache. In fact, I have had a headache every single day for as long as I can remember. I call it a baseline headache, it is always there and at times it gets much worse or I get a migraine. I cannot remember a day that I didn't have one. I have been getting migraines since I was a kid and I am 47 now. Topamax changed my life

I am with you on the flashing/blinking lights. They will trigger a migraine instantly....strobe lights are the worst!
