Quote: its that disc sticking out and pressing on that big ol' nerve there
This is a VERY controversial topic. When John Stosney, the 20/20 reporter (I think that's his name) covered it, some people were FURIOUS at the very idea that their back pain might have an emotional COMPONENT.
Sarno says that this "bulging disc" stuff is basically bogus. That if you x-ray a huge sample of the general public, you'll find that many many-- if not most-- people have "bulging discs" and no pain whatsoever. That you can compare the x-ray of a person with severe back pain with that of a person-- or dozens of people-- with no back pain and that the x-rays will be identical with respect to the appearance of the discs, vertebrae, etc.
In fact, the reporter's brother had had back surgery (which BTW did NOT cure his back pain) and he was livid at Sarno, the book, the theory, and everything else that might hint that his unsuccessful back surgery was not necessary. It was kind of embarrassing for the reporter.
I suggest you not believe one word of what I've written (I'm probably remembering it wrong anyway), but investigate for yourself.
