The spine is composed of multiple bones, known as vertebrae, and soft, jelly-like cushions, known as intervertebral discs. As the bones move along the facet joints, located at the back of the vertebrae, the discs help to distribute the load, acting as shock absorbers. In a normal spine, the discs should remain within a confined space between the bones, held in place by fibrous tissues that keep the gel contained. There are also nerves that lie behind the vertebrae and the discs, controlling your arms, legs and bladder function.

A slipped disc, also known as a herniated nucleus pulposus, occurs when the disc material moves (or slips) out of its normally defined space, irritating the surrounding nerves and causing a host of painful symptoms. This tearing of the tissues around the disc can happen when your back is under extra strain, such as when you are carrying a heavy load, or making a sudden movement.
