@elsa. I have neuropathic and bone pain from chemo and two stem cell transplants for lymphoma. I also get IVIG to help with a compromised immune system. I don’t feel IVIG does anything for my pain issues…if anything it can sometimes make it worse. Granted I don’t have MS, but I am very informed on my therapies and I have not seen anything about IVIG improving nerves.
I had bone pain from my autologous transplant (using my own stem cells), it only got worse with second allogenic transplant from sister’s cells…so I have my doubts about stem-cell therapy for nerve-related pain. There has been some success with stem cell therapy for joint pain and ligament/tendon injuries, but it’s not a medically accepted therapy yet for nerve pain. Most places offering stem cells for nerve pain are chiropractors with a lower threshold on treatments…insurance won’t pay for it either.
Have you tried Gabapentin, Lyrica or Cymbalta? Some people get relief from these. Also massage which increases blood flow and loosens muscles that tense from pain.
Ketamine is a strong medication used for anesthesia, much like a pain med. I have not heard of IV lidocaine, but it might help…though I would think it would work best administered to the location with the pain. Steroid injections might also help especially if it’s related to nerve impingement from inflammation (maybe from botched surgery?).
Hope my experience helps….Best of luck!!
