Re: bulging vs. herniated disc - what is the difference?
The only real difference is the amount of bulging. A herniation has a set minimal amount that the disc is over the edge of the vertebrae, a bulge is anything less than that....
as far as dessication goes, it means that the disc is drying out and has less of a height than it did, compared to the others.
It happens to everyone as they get older. It's a normal finding, and for most , does not contribute to causing pain, although in some others, it might.
