I am due next month for my second lot of rhizotomys. The previous was two years ago and it worked well and lasted for 18 months. The operation was done in the lumbar region, the top of my back and my neck. My mobility improved immensely as did the pain. However, I am hearing stories of a side side effect of possible loss of some bladder control from other people and wondering myself if this could be so. I do not know if this could be so. midgley
