Well went to my knee surgeon about having a replacement, he said no way will I do surgery on me with the R.S.D. Only if you have a nerve doctor tell me that your R.S.D will not go into the other knee that I should replace... Well guess what there is no gaurantee that it won't it's a gamble and I don't think I can gamble like that again... So now they are sending me back to the doctor that want to do the nerve block yipee can't wait poke and poke hate it but I will try anything... One thing is for sure 3 specialist has said my knee needs a replacement and all 3 said they won't touch me so now what do I do any advice for me? This R.S.D SUCKS!!!!
