Degenerative disc disease is the term for normal changes in your spinal discs that occur with aging. Spinal discs are soft and compressible and act as shock absorbers for the spine, allowing you to bend, twist, etc. With age there are changes to the discs because of injury, loss of fluid, tears, cracks, etc. The degenerative disc condition typically occurs in the lower back and neck. Depending on the location of the affected disc, you may experience severe pain in your back, neck, arm and leg.
