Anyone with first hand experience? I've been through PT, injections, ablation and this is the next step. I do not want it be and I'm pushing for disc replacement. I have 1 fusion that's 23+ years old and I was out through 2 years of agony before that was done. Those discs are still fine. My lower disc are really bad. I told the doctor I don't want to go that route but I'm not getting any other options. I am very active duty including hiking, biking, swimming, etc.
