asymmetric disc bulging?

Answer 1

Can you be more specific? Where in your spine? And what is your question?

Answer 2

Disc bulging is very often asymmetric. As forces acting on a disc try to push it dorsally (directly backward), its movement is stopped by the ligaments there. . . . good thing too, or it would run right into the spinal cord.

Bulging occurs when the force going dorsally is added to a rotation force, which allows the disc to bulge to one side of the ligament. This is where the nerve roots lie, and in the low back this leads to sciatica.

Hope that answers the question.
