He has his own patent? I never heard of that. I saw a excellent neurosurgeon And he did not recommend surgery on my spine because I don't have spinal cord interruption, And my pain is not debilitating. Keep in mind It's completely common to have many amended surgeries after a surgery. There are plenty of people that have had multiple surgeries and are in more pain then they began with. I have had steroid shots, I also had a busvicaine shot Procedure in my lumber. It is a prequel to see if nerve end ablasion would work. Unfortunately it did not. I'm pretty positive i'm done with shots. Nobody knows how your body will react to anything. Once again I'm brand new to this so I've noticed. I have responded to people when they don't get it and wrong people are getting my responses. Be well.
