I've been sick with an undiagnosed condition with symptoms similar to Giardia for quite some time now. (If you'd like more information about my symptoms, check out some of my old posts where I've described them in detail.) I've had several stool cultures done but they have all come back negative. I was wondering if anyone who had Giardia may have had a hard time getting diagnosed or treated or if that is something easily found in stool.
