My Dr just recommended this to me and I've heard too many stories that's not good. But I said long time ago I would never have back surgery, but now my allergies are so bad that when I sneeze it's killing my back and the allergy shots aren't helping. But I won't have the surgery.
See if this dude recommends someone in your area. He takes more of a natural approach over traditional medicine. His shows are very informative....imho.
