Traction can, in fact, reduce pain and the displacement of the disk protrusion. Another treatment is exercise. If that does not work, surgical considerations might be explored. I should emphasize that surgery is always the last result, with the exceptions being infection or cancer. For the most part, it is safe.
Some patients have the bleeding without pain.
If you take it daily, then blood work should be done every six to 12 weeks. Blood count, liver, and kidney studies should be done routinely, on a regular basis. You can also have it from bone spurs from the body's attempt to restabilize the spine. The mere presence of disk feature on X-ray has no predictive value as to whether or not it is responsible for the patient's complaints. If your doctor says you have degenerative disk disease, don't go crazy.
