I found this site by my usual bird walking from a topic in google. I am a woman over 60, and not yet retired, but I fell at work 7 months ago...I work in Special Ed at a school district, so I am covered partially by worker's comp. I have had MRIs, CTs and nothing found. But I have head aches, vertigo, ear pressure, "head buzzing". I have latent responses to stimuli, like loud noise so I wear earplugs when I go out. I sayed home for months which did little to help. I decided to try to go to movies...I cannot watch previews as they go too fast and cause an instant reaction. I go to plays and as long as I concentrate just on the dialogue I seem to be okay at least during the production. The PT suggested exercises and to play games on the computer to retrain my brain, but if I don't have an instant reaction I end up with one a few days later. Enough about me...I am trying to go to all the sites you suggest. So I thank you
