Welcome to Neuro Talk. I am sorry to hear about the auto immune problem. Your doctor should have had more compassion. Maybe it is time to move on and find some good doctor who can help you to heal. There is always hope Susie. I found a Physiatrist. This specialty treats for pain AND the whole body on a cellular level. she did more for my PN or RSD than any other doctor. I take B12 shots, and that has helped. I also have a lotion that has a number of ingrediants, that helps with pain. I did not get this from shots, but from surgery. There has been dicussion on this subject of injections, and adverse effects on this site. More folks will jump in to try and help you. I also have auto immune problems, from a virus, and epson Barr. I went to Mayo clinic for DX. A teaching hospital is also a good place to try, more heads get together to try and help. Keep your spirits up. NT will be here for you. ginnie
