How do disc injuries cause back pain? |
 |

|
A tough covering surrounding the discs called the annulus has nerve fibers innervating it. The annulus can tear leading to disc herniations. The tear itself can be quite uncomfortable. As we get older we develop degenerative changes to the disc space, which can alter the rest of the spine causing wear and tear on the vertebral endplates, the facets, and the ligaments. All these changes can lead to back pain as the body tries to accommodate the injured disc and lead to chronic changes that are unhealthy and painful.
