About 10 years ago, I started having really bad low back pain and could barely get out of bed some mornings. Different doctors told me different things. I tried chiropractic, acupuncture, stretching - nothing was helping. Then I came across one of Sarno's books. I was very skeptical, but I found that within 20 pages, he had described my situation to a tee. I followed the advice in the book and was back to running and yoga within a week, and was lifting weights again a couple weeks later.
Sarno's books and theories are a bit outdated at this point, but we now have people like Howard Schubiner and Nicole Sachs, and things like Curable.
