Sorry to hear you are doing so bad. I had the RF done on my neck and back. It was really no big deal. You stop and think about it, look at the pain you are in now with no relief, its worth giving giving it a try. My dr did them under very light sedation. I can only say, that he did hit one spot on my back that got my attention and I got his attention. Would I do it again, you bet. For the first time in 15 years my neck pain is totally gone. I have had every thing done short of surgery on my neck & nothing worked. I had horrbile neck pain and it felt like I had soft balls under each shoulder blade. In one treatment he got rid of a pain no one could.
As for my back, I got about 9 months of relief, the pain never went totally away but it was alot more bearable. There really was no recovery except the first 24 hours. I went home and just relaxed. I think I may have felt a little achey for a day or two, but for me the pain relief started happening in 4 days. I have heard others state it took them longer. So, we are back to the old, everyone is different on how they will respond and react.
I am not sure what you mean by it affecting movement or strength, so I really can't answer that one......Susie
