I understand the concept of controlled injury. The technique used on me was quite different, it was a process my therapist called "scraping." The first time it was done on me was 14 years ago when I had a case of plantar fasciitis so bad that I couldn't walk in the morning, I had to go around on my knees for about 20 minutes before my feet would loosen up enough for me to be able to walk. The scraping was excruciating, but I stuck with it. It got better, so that by the end of treatment, it was quite tolerable. But it proved to be totally effective, as I haven't had a problem with my feet since then. Several months ago, I started having problems with tendinitis in my right elbow. I found a therapist in my area who does that treatment and had the same thing done to my elbow. It has helped a lot.
