I had endoscopic surgery at L5/S1 in 2018 at Arizona Spine Institute in Phoenix. I had severe sciatica for about 6 months due to disc fragment in the foramen. The pain remained for about 3 months and then diminished by about 50%. I then had a steroid injection and that diminished the remaining pain to almost zero after a few days. A before and after MRI revealed the original disc fragment had almost been removed however there remains a small fragment that as of now is not causing further pain problems. Done under sedation and took about 45 minutes. I see it as a good alternative if applicable.. Not many surgeons around that do them. I live in Connecticut.
