i agree with both the previous posts..nerve blocks can hurt. I can say from my experience that my did, but the doctor i had was not a caring person and i had alot go wrong with mine..i can tell you that for the first three nerve blocks i got some relief!
Ive also done accupuncture, and i loved it. it was a very relaxing experience for me and before the RSD got out of control it did help to manage my pain. The disease now has progressed so much that i cannot do it any more though..
i have been through alot of different treatments and have tried a whole ton of stuff... i recently changed PM doctors and the new man i am seeing is amazing i had the bone scan done( which you should know does not always show signs of RSD, there are alot of od RSDers that dont show signs in a bones scan) and i have an EKG done as well as a nerve test done to conclusivly diagnose the disease, and yes i def have it and its spread. lol
If you have any questions i can try to help.. please anything dont hesitate to ask!
