text: Discs are thick gelatinous 'washers' between the bones in the vertebral column and act much like a shock absorber to prevent walking or running from jarring the brain (which is also protected by a liquid around the brain and spinal cord). Because of injury or simply aging, the discs wear and one side of the disc bulges outward. The shift in the weight distrubition causes pinching on nerves from the spinal cord and causes pain, numbness, or even loss of motility (as the pain can be overwhelming). For minor instances, bed rest and muscle relaxants and pain medication are used. However more serious events will bring the doctor to suggest fusing or joining the bones together. The operation is not very serious but would take weeks before the patient could return to normal activity. Fusing the bones does reduce flexibility somewhat but a small sacrifice compared to the pain and discomfort. Most of the disc problems occur in the lumbar region of the spine but sometimes can occur in the cervical region (neck). Sometimes a good back brace will provide some relief but it is important to learn good work habits in lifting objects (use the powerful muscles of the legs, not place stress on the back muscles and discs). Long hot baths will help to relax the back muscles but do nothing for the disc. Some people suggest chiropractors as an answer, and while they may do some good, I suggest an orthopaedic surgeon  to manage the problem. This problem is referred to as a 'slipped' disc or a herniated nucleated palposa or a bulging disc.
