A slipped, or prolapsed, disk is a medical condition affecting the spine that can cause severe lower back pain. The bones that make up the spine are known as the vertebrae. The bones of the vertebrae have cartilage disks between them, connective by a gel-like tissue. A slipped disk is caused when the soft part of the disk bulges through the circle of connective tissue. The disc does not actually slip out of place, but it bulges, causing a push on the spinal cord.
A slipped disk can many times be symptom free. However, when pain does occur, it is due to the pressure placed on the spinal cord or nerve roots. This type of pressure can result in feeling muscle spasm, paralyzed muscles and/or disturb feelings in the limbs, and problems controlling the bladder,
