Disc herniation

Spinal discs are flat, round structures that consist of a tough outer ring of fibrous tissue surrounding a gelatinous center. These cushioning spinal discs are like shock absorbers, and can wear out, especially with punishment. The disc begins to slip out of its place between the vertebra, causing a bulge and pain by irritating nerves within the discs outer shell. If the disc herniates, or ruptures, the resulting protrusion can press on a nerve of the spinal cord or even on the spinal cord itself. Excruciating pain will be felt locally, and typically in other areas of the body, legs or feet.
