I would suggest that you click on the header above and order MH's booklet which tells you all about doing a Kidney Cleanse, Bowel Cleanse, Parasite Cleanse and then Liver Flushes and an Orange-Juice Fast. This will clean you out and set you on the path of great health.
Assess your diet; so many of our troubles begin with what we put in our mouths! Check out the raw food sites which talk about living foods, as opposed to the cooked foods which have no enzymes.
I had a friend who studied to be a Traditional Chinese Medical Doctor and I recall that she spoke about the connection of the knees and back to the kidneys, so perhaps that is the root of the problem. However, putting a label on a specific illness or disease does not address the underlying weakness of the body. It is best to strengthen the body.
Whatever disturbance you may have in your body, a good cleansing should be of great assistance.
