what is the difference between a bulged disc and a herniated disc
A herniated disc falls into the category of a non-contained disc disorder, whereas a bulging disc would be an example of a disc disorder that is contained. A bulging disc means that there is no tear or rupture in the annulus fibrosis (outer layer) of the intervertebral disc. A bulging disc is also known as a disc protrusion. Essentially, a small bubble of disc material protrudes into the spinal canal.
