After a week of the flu, i'm not better and have developed a new symptom: diarrhea. what can i do?

Question the flu dx: IF you really HAD the flu, it isn't causing your diarrhea now. As long as your stools aren't bloody, you don't have a fever and your abdominal pain is minor after an episode of diarrhea, just keep orally hydrated and eat smart. Avoid caffeine, milk and fatty/fried/greasy foods. and eat bananas, steamed rice, apple sauce, lean protein and toast [a little jelly is okay, but no butter].
