Hi Mandi and Welcome!
Sorry your RSD did not stay in remission. Sorry you had to find this group, but it's great. I'm somewhat of a newcomer myself.
My RSD is left hand/arm so my nerve blocks are given in the neck area.
With me they have tried different drugs in the injection. Clonidine(sp) has helped a lot.
I just finished a SCS trial which at one time I swore I would never do. I really have to think a lot more on whether I ever want a permanent SCS. I'm going to look into "Calmare" or laser therapy in the meantime because they are less invasive.
Treatment decisions are so difficult because there are no definative treatments for us.
Hoping you find some relief
