Degenerative disc disease is when one or more of the discs between the vertebrae of the spinal column deteriorates or breaks down, leading to pain. It often happens as people get older.
There may be weakness, numbness, and pain that radiates down the leg.
Despite its name, degenerative disc disease is not a disease, but a natural occurrence that comes with aging.
The rubbery discs between the vertebrae normally allow for flexing and bending of the back, like shock absorbers. In time, they become worn, and they no longer offer as much protection as before.
