Hi Sue!
You mentioned the colors affecting you, do you mean lights or specific colors? My neuro had asked me if there were any colors in specific that bothered me and I couldn't tell her anything in particular (hadn't ever paid attention th that specifically), just brightness, neon lights that sort of thing. Motion coupled with light is awful for me.

You mentioned that its better for you since your surgery- funny,it didn't bother me until AFTER surgery. Weird isn't it? I can't even watch fireworks now (selectively at least), movies can be problematic, concerts, lots of things can really be bothersome that weren't before. Really strange. I wonder why.
