first of all be certain that your doctor is open to new ideas, suggestions etc and does not have a fit when the patient actually produces coherent opinions about alternative treatments.
then go to this link and print it out, take it to your dr and discuss it with him.
and don't let him off the hook. make sure he answers all your questions to your satisfaction.
perhaps the article will suggest a course of treatment adapted to your situation.
personally, i would not play around with Epsom Salts or any other "flushing" procedures. you do not yet know what is going on in your body and you do not want to exacerbate any problems or create new ones.
