Mysteries of my Aching Body

I have played sports all my life. At many different periods, I have injured myself to varying degrees. In particular, I have had chronic ankle pain and a damaged rotator cuff for many years. In some instances, including these, I have consulted with a physician. It always seemed that the various doctors I saw didn't really know what the problem was, and that they were just reading the Generic Medical Playbook. I therefore was very interested in this article in Time. I am not knowledgeable enough in medicine to make an intelligent assessment of the information in the article, but is seems to be at least superficially logical. Thoughts?
