A bulging disc is a condition related to the spine, usually the lower back, occurring when a disc bulges through a crevice in the spine. It happens when the disc shifts out of its normal radius and most often occurs simply as a result of age.
Bulging disc symptoms depend on the location. Some patients may experience symptoms of pain and discomfort in the legs and feet, others in the arms and in other regions of the body. The diagnosis for bulging discs is usually made after a complete medical history has been taken and MRIs, CT scans, and/or X-rays have confirmed the presence of bulging.
