I have a friend whose lower four vertebrae have no cushioning between them. They are bone to bone. He also suffers from sciatica down his right leg because the nerve gets pinched. He had surgery about ten years ago where they cleaned out the stuff that has grown inside his vertebrae since it was pressing on his spinal cord. His doctor says it's a question of when he'll need surgery again, not if he'll need surgery. I suggested he look into the Gokhale method since it's my impression it could be helpful for him. But I would like for him to get a more educated opinion before he makes any decision about this. Do you think Gokhale method would help him.
