Degenerative disc disease isn’t exactly a “disease” but rather a reference to the various changes that naturally occur in your spinal discs due to aging or excessive use. The spinal discs are components between the vertebrae responsible for shock absorption; they cushion the spine, helping you remain flexible and mobile. However, as you grow older, the spinal discs start showing signs of wear and tear, leading to spinal pain along the spinal column, usually in the lumbar region.
Due to limited blood supply, the spinal discs aren’t capable of self-healing when an injury occurs. Degenerative disc disease may lead to several changes to your spinal discs — they may dry out, start thinning, or harden. When your spinal discs start thinning, you may suffer significant pain due to the subsequent inflammation of your bone and joints. You may also suffer from inflammation and severe pain if the jelly-like fluid within the discs leaks out due to injuries. Most people eventually suffer from disc degeneration, but only some people experience pain associated with disc degeneration.
