I was diagnosed with C. difficile in June, referred to an infectious disease specialist, and was involved with a blind drug test. My symptoms returned October, November , while I tested positive for C. difficile again, the infectious disease people say it is a false positive. I lost 20 pounds with the first diagnosis, have lost a further 10. I have swelling in my abdominal section, and also on the right side of my stomach. My doctor refuses to do anything without ruling out C. difficile
