I have had the procedure on my L4/L5 disc. I was impressed at hoe minimally invasive it was. I was able to walk out of the hospital the same day with nothing more than the equivalent of a band-aid over the incision. It unfortunately didn't help in my situation as I have degenerative disc disease. Currently both my L5/S1 and L4/L5 have annular tears, and I have several other bulging discs as far up sa my T12. I wouldn't worry too much about this procedure, and I hope it works better for you than it did for me. Good luck!
