Have had RSD for several yrs. now. Went for experimental alternative treatment which involved an IV push. The nurse stuck the IV in my right hand (hand I always use). I immediately felt pain there which soon spread into my wrist and up my entire arm. I phoned the dr. and explained what happened. He said "why did you let her put the IV in your hand. You should not go near RSD patient's hands for IV insertion." How was I supposed
to know that information. Apparently the hands are extremely susceptible to nerve injury as there are numerous nerves in our hands. My Pain became excruciating for a while. Now the
pain has subsided and is tolerable but I must restrict use of my hands for typing, etc. as it causes pain again.
Just rest your hands and if necessary you may consider TPI's if it does not subside.
Good luck. Hopefully, like mine it should resolve itself in time. Mine did not turn colors but it was freezing cold.
Good luck,
Sydney
