Welcome to the board Gail. Normally scar tissue will develope early after surgery, not 15 years later. This sounds like new issues. You can try Lyrica for nerve pain. It doesn't work for me, but it has for some on this board. Is this the same doctor that did your surgery that you are going to now? I think I would take my test and get a second opinion. It's true that they don't normally operate on just scar tissue, but it sounds like you have something more than scar tissue. I have scar tissue but also entrapped nerves from narrowing of the canals. My surgeon is asking for surgery for me now. I had the trial spinal stimulator. It also didn't work for me as most of my pain is in my back. It did help with leg pain somewhat. Hope you can get some resolve to your issues.
