I contracted food poisoning from dinner last night. I had strong abdominal pains and frequent diarrhea in the middle of the night (no nausea or vomiting). It continued in the morning, but has become less and less frequent as the day has progressed, and has probably stopped now. Ordinarily, I would not be concerned at all, as it seems I m recovering quickly, but there has been blood in my stool. It could be from hemorroids, as the diarrhea and constant wiping as irritated my rectum, but I m not sure.
