Low Back Pain
Low back pain is a major source of chronic pain. It is estimated that it will affect 80% of all people at some point in their lives. It is the most common cause of job-related disability. The most common causes of lower back pain are injury of overuse of muscles, ligaments, or joints, or pressure on nerve roots in the spinal canal. Nerve impingement can occur from herniated discs, spinal stenosis, spondylolisthesis (when there is a slippage in between vertebrae), compression fractures, or spinal deformities such as scoliosis. Finally, the discs themselves may be a source of pain.
