I assume that you are refering to joint issues. If thats the case I can tell you that I had developed chronic shoulder and wrist pains that were threatening to put of a stop to my passion for whitewater canoeing and that my pains completly disappeared after my 1st 40 day MC.
Having said the above what you need to keep in mind that that the MC or any of these other cleanses on this site don't CURE anything. The way they work is to take the trash out so the body will heal itself . If you don't change your habits and keep putting the same crap back in as before you will continue to have problems.
