When first diagnosed with RSD I am betting that most of us had never heard of this terrible disease - which is in itself a big problem - but you are in a minority that it is diagnosed early on.
I have RSD in my left upper extremity (resulting after left rotator cuff and bicep repair surgery) and am left hand dominant, so I can relate. had a total of 13 sympathetic nerve blocks - no regrets there. They helped me to a certain level - and any help with RSD is huge. Directly following each block my husband drove me to my physical therapist who was able to manipulate movement more due to the drugs I had in my system still. I am convinced that this combination was a good decision.
I continue to fight this disease daily and pray that it isn't spreading, but I do know that the blocks gained some improvement, and that it has a better chance of positive impact early on.
Best wishes to you - and do your best to find one positive thing in each day no matter how small.
