I have also had ablation in my back due to back pain (too many accidents). Once done it was wonderful to be able to take my favorite past-times (kayaking, biking, hiking) and getting to enjoy the days without the pain. My ablations were done under light sedation but the other choice was 'local' anesthesia. My ablations don't last as long as I'd like - I get them every six months. But that's OK - I'm up and around pain free.
