How does degenerative disc disease develop?
Degeneration of the cartilage in the discs is a natural part of aging. Tears can also occur in the outer lining, or annulus, of the discs. In adults, the annulus contains nerve fibers, which means a tear in this region can be quite painful. As disc degeneration progresses over time, the associated pain usually gets better. This is because back muscles and ligaments work to stabilize the vertebral segments. Eventually, however, the muscles and ligaments become lax and pain returns. Disc degeneration seems to occur more quickly in some than in others. Also, for reasons unknown, some individuals experience much more pain with these degenerative changes than others do. What are the symptoms of degenerative disc disease? The primary symptom associated with degenerative disc disease is midline back pain. Individuals may also experience “referred pain” in the buttocks, pelvis and sacroiliac joints, as well as in the backs of the thighs. Pain associated with this condition usually intensifies
