hi. i just had something weird happen to me. I was driving and my head hurt. behind my left eye - that whole front side of my brain. When the sun hit my forhead, it hurt my brain to a degree, it felt like a chemical reaction. While driving, my eyes went white - all i could see was white and my eyes felt like they were floating. It lasted until the sun was blocked. I kept driving and told my passenger something was wrong. My brain felt like it would do whatever it just did again. So the passenger took over. I dont know what it was. I can see fine now, but my brain still hurts.
