1).The gel material is irritating to your spinal nerves, causing something like a chemical irritation. What is a herniated lumbar disc?Ī herniated disc occurs when the gel-like center of your disc ruptures out through a tear in the tough disc wall (annulus) (Fig. Your spinal cord and the spinal nerves act as a "telephone," allowing messages, or impulses, to travel back and forth between your brain and body to relay sensation and control movement (see Anatomy of the Spine). At each disc level, a pair of spinal nerves exit from the spinal cord and branch out to your body. Each disc has a gel-filled center called the nucleus. It has fibrous bands that attach between the bodies of each vertebra. The outer ring of the disc is called the annulus. The vertebrae are separated by cushiony discs, which act as shock absorbers preventing the vertebrae from rubbing together. There are 5 lumbar vertebrae numbered L1 to L5.
The lumbar (lower back) section of the spine bears most of the weight of the body. Your spine is made of 24 moveable bones called vertebrae. If symptoms continue, surgery may be recommended. Most people improve in 6 weeks and return to normal activity. Treatment with rest, pain medication, spinal injections, and physical therapy is the first step to recovery. Back or leg pain, numbness or tingling may result when the disc material touches or compresses a spinal nerve. A herniated disc occurs when the gel-like center of a disc ruptures through a weak area in the tough outer wall, similar to the filling being squeezed out of a jelly doughnut.
