Herniated Disc Definition
Definition
Discs are small circular cushions between the bones in the spine. The bones are called vertebrae. The discs are compressible. They act as cushions for the vertebrae. A herniated disc happens when discs in the spine bulge from their proper place. This is most common in the lower spine.
