Hi,
Sorry to hear about the problems you are currently having I agree with Desi that you don't have to have an injury for RSD to spread.
My leg swelt up a LOT overnight and my doctor admitted me into hospital as he was very concerned and thought that I may have either a blood clot or Compartment Syndrome - thankfully I didn't!!
It's so discusting that medical proffesionals wont listen and believe their patients and say that you need an injury for the RSD to spread - I hope things work out for you soon
