Anyone out there had and RF procedure done? I have lower back pain, bulging discs, degenerative disc disease and several vertabre injuries. I want to put off surgery for a bit since I have had neck fusion this summer as well as an ankle fusion. My doc recommends RF for my lower back. He said it should keep the pain at bay for a good 16 months which sounds like heaven to me. If you have had this done, what has been your experience with it?
