If you are convinced that might be the problem, chelation or detoxification would be the solution, otherwise, it might just be an unecessary strain on the body to do chelation. As I remember, there is a HYPERHYDROSIS (sweating only hands and feet,...HYPO-sweating on other parts of body also) forum here (thyroid condition) at Curezone, but also check 'foot pads' and 'magnetic (also forum) clay baths'.
Apple Cider Vinegar, Alkaline/Acid, Water and Salt forums could help with skin problems.
