I've had RSD for about 7 years now. It started after an ulnar nerve transplant and relocation of the median nerve with a fatty pad graft. I have constant pain to the bone. I no longer have lost my finger nails though and the hair stopped growing. But, the color in that arm is always abnormal and I can't control the pain. Even with nerve blocks in my neck and pills. The muscle is atrophying and the bone isn't as large as it used to be. I don't recommend any nerve transplants to anyone, ever. On top of that I have Multiple Sclerosis and congenital hypothyroidism. I'm just in pain 24/7.
