Symptoms of Degenerative Disc Disease

The most common early symptom of degenerative disc disease is usually pain in the back that spreads to the buttocks and upper thighs. When doctors refer to degenerative disc disease, they are usually referring to a combination of problems in the spine that "start" with damage to the disc, but eventually begin to affect all parts of the spine. Problems thought to arise from the degenerating disc itself include discogenic pain, and bulging discs.

Discogenic Pain

Discogenic pain is a term back specialists use when referring to pain caused by a damaged intervertebral disc. A degenerating disc may cause mechanical (or structural) pain. As the disc begins to degenerate, there is some evidence that the disc itself becomes painful. Movements that place stress on the disc can result in back pain that appears to come from the disc. This is similar to any other body part that is injured, such as a broken bone or a cut in the skin. When these types of injuries are held still there is no pain, but if you move them they hurt.

Discogenic pain usually causes pain felt in the lower back. It may also feel like the pain is coming from your buttock area and even down into the upper thighs. The experience of feeling pain in an area away from the real cause is common in many areas of the body, not just the spine. For instance, a person with gallstones may feel pain in the shoulder or a person experiencing a heart attack may feel pain in the left arm. This is referred to as radiation of the pain. It is very common for pain produced by spine problems to be felt in different areas of the body-including the back.

Bulging Discs

Bulging discs are fairly common in both young adults and older people. They are not cause for panic. Abnormalities, such as bulging or protruding discs, are seen at high rates on MRIs in patients both with and without back pain. Some discs most likely begin to bulge as a part of both the aging process and the degeneration process of the intervertebral disc. A bulging disc is not necessarily a sign that anything serious is happening to your spine.

A bulging disc only becomes serious when it bulges enough to cause narrowing of the spinal canal. If there are bone spurs present on the facet joints behind the bulging disc, the combination may cause narrowing of the spinal canal in that area. This is sometimes referred to as segmental spinal stenosis. View animation of bulging disc.
