I've had the aura without headache for about thirty years and RSD only ten.

I get it only about every year on average and it lasts only 15 minutes to half an hour. When I first got RSD the frequency increased dramatically but now I'm getting it less than ever since getting the migraines.

I get a sense of discomfort with them but the real problem is that I usually can't see straight. Anything in my direct field of vision appears kalaediscopic.

Caffeine tends to bring it on more than anything else but there are other triggers for me.
