After being diagnosed with RSD in 1988, yes I said 1988, the mode of treatment included surgical sympathectomies. My result was more intense pain & the procedure being irreversible. If I had another chance, I'd never have it done.
Residing here in Iowa, I have trouble enough just finding doctors willing to prescribe pain meds. If your doctor wants you to have this done, my suggestion would be too run. Good luck to you...............................
