thanks Bex, I couldn't figure out why the violent reaction/going backward til I realized it had to be the dentist office! It was the only possible reason. I had to call fire dept. to help me up...full of bruises today! sensitive...yup...much better today..no falls or extreme spasms.. just very tired and painful hip/neck..thanks again Bex,what would I do without your sane thinking and logic. kathy
