Has anyone ever had the abulation where they inject heat into the nerve to deaden them? I am going thru remedial injection now with lidocane and this is the next step to try and get my chronic pain under control. I'm wanting to know how successful this procedure is. I have read it's only 50/50? I have hardware in lumbar L2-5 with daily pain that has very much affected my quality of life. Any info would be appreciated.
