Our spinal discs may be thought of as a jelly filled doughnuts. The nucleus pulposus is the jelly, acting as a shock absorber surrounded by fibrocartilaginous tissue called the annulus fibrosis. The annulus fibrosis is a very tough network of fibers that is a ligament keeping the vertebrae above and below together as well as giving form to the disc. There may be injury to the disc, such as herniation, or collapsed disc. Nerves can be irritated, with possible severe consequences, such as shooting pain down the leg, numbness, tingling, difficulty lifting one's leg, difficulty walking, troubles getting to sleep due to pain, etc. Chiropractic seeks to help the body restore motion and assist the body in self-healing.
