![]() ![]() This area continually absorbs the impact of bearing the weight of the upper body. The most common location for bulging disc is between the fourth and fifth lumbar vertebrae in the low back. Over time, the discs start to degenerate and weaken. Spinal discs absorb the wear and tear that is placed on the spine. If the outer layer of the disc tears and the soft inner part of the disc leaks out, the result is a “herniated disc.” Perhaps most importantly, you should know that a bulging disc may become a herniated disc. However, a bulging disc has not broken through the outer wall of the disc (ruptured). A disc that is damaged may bulge, pushing into the spinal canal and causing pain. It is also important to note the difference between a bulging disc and herniated disc. About 10% of disc injuries affect the upper portion of the spine. Herniated disc: A bulging disc’s outer wall tears, allowing the inner fluid to escape.Ī majority of disc injuries occur in the lumbar (lower) region of the back because the lower back bears most of the torque and force of daily movements.Bulging Disc: The disc’s outer wall remains intact, and the disc protrudes more than 180 degrees of the disc’s circumference.Disc protrusion: The disc’s outer wall remains intact, and the disc protrudes 180 degrees or less of the disc’s circumference.There are three different distinctions for disc problems: When this type of pain develops, especially after an accident or injury, it is important to consult your pain doctor. Depending on which nerve is pressed by the disc, the pain can appear in a leg, arm, or elsewhere. When a disc “bulges,” part of its tough outer wall can protrude into the spinal canal and press on a nerve, which causes pain. Sometimes spinal discs are likened to a jelly donut with a central softer component (nucleus pulposus). Discs are the gel-filled pads that cushion the individual vertebrae of the spine, acting like shock absorbers and allowing movement and flexibility of the vertebrae. A bulging disc is a condition in which a disc loses its original shape and expands (bulges), which can place pressure on a surrounding nerve root and cause pain.
