I've always been super sensitive to light, sounds etc. I can't stand LED, or the new, as I call them "evil" lights that are on cars, the blue looking ones. One time last year in PE, our teacher told us the next class's we were going to play strobe light volleyball, I got out of it. I get headaches everyday and by now I can't tell if they are migraines or headaches, is there any link between SPD and headaches??
