My back and knees were hurting. My back has always bothered me. My knee has been messed up for at least two years. I was using a cane. I’ve used heat, exercises recommended and none of it was helping. When I watched the film on my first day, I thought there is no way this technique would help me. Now my knees don’t bother me hardly at all. Dr. Eric and Dr. Emma helped me tremendously. When I left the office, I walked out almost perfect compared to when I came in.
