If you have parasites, no stool tests will reveal it. read the debates on the protozoa forum. Go see Dr. Kevin Cahill in NY city, the world's very best doctor in proper diagnosis, because he is the only one who does a test that no one else does; And natural treatments will get rid of them, and you do not know what you will be treating. This is serious stuff; go get proper help. And please please stop trying to guess what you have based on what other people say on this forum.
