Low back pain is a common condition. It can be caused by lumbar sprain, spinal stenosis, disc herniation, and different degenerative spinal disorders. The term discogenic pain means one or more intervertebral discs are the pain source.
The spine is made up of a series of connected bones called "vertebrae." The disc is a combination of strong connective tissues which hold one vertebra to the next and acts as a cushion between the vertebrae.
