Just now I felt an insane brain zap in my head as I was sitting on a bench at the park. It was as if a flash bang set off in the inside of my brain between the hemispheres and I saw a light turn on and off. It lasted like 2 seconds. What does this mean?
I had sinus surgery years ago and haven't had the migraine issue anymore. I was having two a week for years. I might get one a year. Good luck.
