Degenerative spine disease is the breakdown of intervertebral discs. As we grow older, the intervertebral discs dehydrate and the proteins that keep them healthy break down. As the discs deteriorate, they become less effective at supporting the vertebrae. This can cause the vertebrae to become slightly displaced and put pressure on the nerve roots that travel in between the vertebrae, press on the spinal cord itself or cause bulging or herniated discs. Pinched nerves and Sciatica are also common symptoms.
