Can someone tell me if this disease would cause my imune system to attack the foriegn material in my back(ie.. screws, rods fake bone. The reason I am asking is because I have had two back surgeries and it still is not getting any better. I had my second one almost 3 months ago and I feel like I did before I had the surgery. I can't even go to the store and shop for 30 minutes without being sidelined for the entire following day. I really wish I could stop hurting long enough to be able to function!
