I had the GI flu last Monday. Symptoms were severely nauseated, fatigue, diarrhea and abdominal distention & pain. I treated it by drinking liquids, jello and moving up to crackers. By Thursday I was better. I am still experiencing severe nauseosuness and I took a phenergan tonite that I had from a surgery which I didn t use. Tonight I am very anxious can not sit still, mind raising and my muscles and joints ache, a lot. Do you have any suggestions on what I should do and perhaps what a dx could be?
