Fortunately, I have zero pain in my Lumbar. The only reason that they had to replace the scs s is because it got zapped when I had carpal tunnel surgery. I feel so terrible telling you that I have zero pain and I am saddened that you have such pain. Have they tried and ablations on you? I have had the them in my neck and my tailbone, and they both have given me 100% relief for six months to eighteen months. If you have not, please check with your PM about that treatment. May God bless you with better success that that which you have had. brotherchuckles80@gmail.com
