This must be very frustrating for you! I would not bother trying to get a doc to listen. They have their minds set and you probably won't budge them. You have been trying all these remedies for so long. There is some debate regarding candida and wether it is friend or foe. Nothing worked for me quite like the moreless website which can be found on this site. Why are candida overtaking you? My belief is that although they bring their problems, they are actually protecting you. I bet you are too acidic. Also regarding the knee, do you have any issues with your teeth? route canals, abcess or fillings even removals? and would those dental issues be on the left?
