I had surgery in 1994 for TOS. Removed rib and scalenopy (sp?). I have always had problems but now I slipped and fell and have re-injured my arm. I am having a lot of problems just like before surgery or maybe worse. I know they told me to never fall, but what exactly happens? Does this close up again? I had good doctors in WA state, but now I am in Florida and don't know of any. My medical doctor admitted he knows nothing about TOS.
