Temperature Measurement Standards.

A bulging disc occurs more often as we age or as repetitive activities weaken the the disc. Herniated discs are more often specifically related to trauma/injury sustained and are more acute (sudden) in onset.
A herniated disc in the upper back can occur when the inner gelatinous material of an intervertebral disc leaks out of the inside of the disc. A thoracic herniated disc can cause upper back pain and other symptoms, such as radiating pain or numbness.Watch: Thoracic Herniated Disc Video.See how a herniated disc occurs and how it can cause pain and other symptoms depending on the location of the disc herniation. Video: The Difference Between Disc Terms. This video explains the differences between the terms bugling disc, slipped disc, and herniated disc.he fact that so many people had thoracic herniated discs but no pain or symptoms is important to mention, as it shows that people may have both upper back pain and a thoracic herniated disc, but that the disc disorder may not be the cause of the thoracic back pain â it may just be an incidental finding.
