Bulging Disc

General Information

Although a bulging disc in itself is not a true herniation of disc material it is commonly included in the category.  It is common for an intervertebral disc to bulge as it is a part of its normal biological function acting as a shock absorber.  A bulging disc becomes problematic when the disc space starts to collapse and the outer rings of the disc begin to bulge out.  This can be compared to air leaking out of a tire or an ice cream sandwich melting.  A bulging disc can contribute to the formation of another condition called central spinal stenosis.

Relationship between a bulging disc and a herniated disc

Sudden stress or pressure on a weakened bulging disc could lead to a disc herniation.  When a disc herniates the inner gelatinous material pushes out through the tough exterior ring of the intervertebral disc.  Click here to learn more about herniated discs.
