If I read this right, you only have a 33% chance of success and an equal chance of making it worse. Doesn't seem like a good bet to me. Get another opinion. I agree with Litauer about the chiropractor. I tried that route. They just give you temporary relief and keep you coming back as long as possible. My bottom two disks are supposedly fused together, probably from heavy weightlifting as a teen. I will not let anyone cut into my back. I tried the injection of a steroid cocktail into the spine. It helped for a while but the pain always came back and had to be done again. I couldn't be taking pain pills and do my job so I tried physical therapy which actually helped a lot. Now I just try to walk everyday and do some stretching. I've learned to live with pain and I'm not going to be crippled by a doctor or addicted to pain pills. Good luck to you which ever you decide to do. Make your mind up yourself because you are going to have to live with it.
