which country are you in. I would bet the dental issues are the root of your knee probs. You know that we have channels in our bodies called meridians and they connect with our organs and also go through the teeth, each tooth is connected to an organ, so for example a heart prob could be due to a wisdom tooth prob, sort the teeth and sort out the problem in that channel. The only solution is to see a biological dentist, they understand the teeth being the cause of health probs. Read up on this and you will understand. There are dental forums, ask torrie may be helpful for you. I would say a visit to the dentist and Ph balancing will be key to your success. You may be eating veg etc.. but is it organic? is it seasonal? (for the area to where u live? and is it raw? (plenty of enzymes to heal). Good luck and best wishes!!
