The flexion distraction technique can undo the nerve pressure and disc compression underlying your discomfort, possibly freeing you from the need for major surgery. The technique, originally developed by Dr. James M. Cox, is based on the application of small, precise amounts of flexion distraction to the part of the spine experiencing disc compression or herniation. As the vertebrae in question are gently pulled away from each other, negative pressure draws the herniated or bulging disc back into position, relieving nerve pressure and pain and moving much-needed fluids back into the disc.
