For the past year, I've had chronic diarrhea, nausea, severe belching (no bloating though), nausea and vomiting off and on, low grade fevers, and my stomach makes horrible, loud watery gurgling noises all day. It all started with an "intestinal flu" that EVERYONE in my workplace contracted last March, (right after a co-worker's dog suffered an "intestinal infection" which cleared with metronidazole.).
