Intervertebral discs are cartilage-like pads that sit between the spinal bones. Discs provide support for the spine and are also a fulcrum for movement. Injuries, like improper lifting or a car accident, or long term postural strain, like having a work station that requires you to be bent forward, are the most common causes for disc problems. A bulging disc occurs when the outer layer of the disc is weakened and it encroaches on the nerve tissue causing local, as well as radiating pain into an arm or leg. A herniated disc happens when the outer layer of the disc tears and the soft nucleus extrudes out from the disc into the nerve canal or spinal cord causing severe, debilitating pain. Less complex or severe disc problems respond very well to chiropractic care and exercise therapy.
