I didn't get RSD from an IV... BUT having to do with the wonderful and mysterious world of nerves... I had a treatment about 3 years ago that required an IV. I was treated at a teaching hospital so the doctor asked if it was ok if med students were about to start my IV and of course i had no problem because being stuck with needles was the least of my worries. But due to their lack of aim they hit nerves in both of my hands leaving 3 fingers on each hand numb to touch. I can still move them but i have no sensory feeling in them. I have just started getting tingling in my fingers for the past few weeks though so maybe thats the sign of recovery on my fingers at least.
