Disc Bulge

A disc bulge occurs when the fibers around the edge of the disc have torn. When this occurs, the soft, jelly-like center of the disc starts to push out. The fibers on the edge of the disc that are still intact begin to bulge out from their usual position as a result of this jelly center moving outward. Left untreated, this bulging leads to a build up of scar tissue and eventually degeneration and arthritis.
Disc Herniation

Disc herniations occur when the fibers around the disc have torn enough that the jelly center starts to push out at one specific part of the disc. When this herniation occurs, it can put pressure on the nerve that moves out of the spinal cord at that location. Pressure on nerves causes more pain, numbness, tingling, and sometimes weakness. Left untreated, a disc herniation always leads to arthritis and disability.
Disc Sequestration

A disc sequestration is the most severe of the disc injuries. With this condition, the soft jelly center of the disc has ruptured completely through the fibers that normally surround it. This leads to the jelly center moving into the space normally occupied by the nerve and causes significant irritation to the nerves and local inflammation. Nerve irritation and inflammation can cause pain, tingling, numbness, weakness, or changes in bowel and bladder abilities. Left untreated, this condition can lead to significant limitations in function and severe disruptions in work, sleep, and home life.
