Anyone who is experiencing chronic lower back pain with numbness, tingling, or muscle spasms may have a lumbar slipped disc. The physicians at the Freeman Spine and Pain Institute, a pain treatment center in Union, NJ, can diagnose a plethora of back conditions, including slipped discs. This condition may occur due to general wear-and-tear of the disc that occurs over time. People who frequently perform bending and twisting motions, or those who spend most of the day sitting are at an increased likelihood to develop this condition, as these actions put undue stress on the disc. It can also occur following a sudden trauma such as a car accident.
