Thank you all so much for your responses and support.
I saw the PM doc today and he feels that although I have some of the symptoms of RSD he doesn't feel that he can make that diagnosis at this time. He said it does not mean that I don't have it though. He is still recommending the sympathetic nerve block. He thinks there is a good chance that it will give me relief over a period of time. I have it scheduled for Dec. 5 and I'll continue with the Neurontin until then and if I feel better I may put the block on hold. He feels the scar tissue from my laminectomy is causing most of my nerve pain.
Thank you all again, best of luck to everyone and God bless each of you!
