I had a good result from several Stellate Ganglion Blocks which I received to treat my CRPS in my left hand and forearm. It is important to have the blocks as soon as you can because if the problem is CRPS, the sooner you block the nerve signals and get your arm moving the better. Also from a diagnostic standpoint, knowing the outcome of the block is helpful for the neurologist. I know what it feels like to have constant excruciating pain, which is what I felt before the blocks. Proud of you for reaching out to this community of wonderful people who are here for you. You are not alone.
