The term “degenerative disc disease” refers to changes that occur because of the age-related wear and tear of the intervertebral discs. The spinal discs between the vertebrae of the spine are shock absorbers that help you remain flexible. They’re made of a soft inner core and a strong external shell, and they prevent your vertebrae from grinding against each other, thus facilitating smooth, frictionless movements.
As you grow older, the spinal discs gradually change shape, becoming weaker and less flexible. They might even display signs of wearing out, and they may eventually break down, becoming incapable of shock absorption. When the spinal discs dry out, lose height, or become stiff, you may suffer from nerve compression, joint inflammation, or bone damages, resulting in spinal pain. Degenerative disc disease is most common on the lumbar spine.
