Well, mine is not W.D. issue, but my CRPS happened from wrist surgery too.
I've tried lots of treatment and mine is not in remission but has greatly improved. So there is hope! Everyone is different with this awful disease so try everything you are able to so you can find what works for you.
My original site (hand and wrist) is not nearly as bad as it once was but yet I too feel it spreading past my elbow (pins & needles, aching) feelilng so far.
For me the nerve blocks and physical therapy with pain meds. have been the best combo. Please take extra vitamin C and Magnesium to help prevent the spreading.
