I read where you had the injections. My Katamine did help for a bit, but was admisistered by a very good pain specialist. He had the very best education. what joanne said was correct. If they can't administer injections, or are not willing to give pain meds, and they are refusing to operate, you need to keep going until you have some kind of resolution. That puts you into a vicious cycle of no help. I am thinking about you, and hope you keep moving forward to get some kind of relief. I do have empathy for what you are enduring. ginnie
