I was seen in the ER yesterday morning for severe

Patient: I was seen in the ER yesterday morning for severe abdominal pain, nausea, and diarrhea. They gave me zofran and a pain med and sent me home. The diarrhea started at 1am Thursday and I am still having it after taking ammodium. Should I be concerned? I try to eat and I get the stomach pain and nausea. The stomach pain started Wednesday at noon. What should I do?
