Hello, I have had 4-5 days of diarrhea and last night very bad stomach pain and rumbling, then I threw up twice in the night. I am feeling a little better today and have not thrown up or had diarrhea, but my stomach still feels tight, crampy, and bloated. It is kind of painful. I am trying to stay hydrated, but does this sound like something more serious than just food poisoning or the stomach bug?
