Hi I've Had Diarrhea On And Off For About 2

Hi I've had diarrhea on and off for about 2 weeks. It started when I had what seemed like a stomach flu with a fever and painful abdominal cramps. After 72 hours I felt better but the diarrhea has stayed. Yesterday, it stopped but then today I have it again. No fever or headaches etc but just the diarrhea.
