Mine are magnified due to having so many concussions (6). My worst one was about 20 years ago. I couldn't speak, or stand up to tell my co-workers what was wrong. I scribbled "jeep....gym bag.." on a piece of paper and they ran got my gym bag which had my blockers in there.
My run of the mill ones cause me peripheral vision blindness and nausea. If I take my blocker (Imitrex) fast enough, I can avoid the residual pain. Which usually is worse the next day and feels like I got hit with a bat in the head. Reminds me a lot of a concussion on the second day. Like flu with a sore brain.
