Gastroenteritis: Your symptoms are consistent with either a viral intestinal tract infection or a type of food poisoning. Treatment consists of good fluid intake,preferably room temperature liquids, , avoiding roughage in your diet and taking either kaopectate or imodium to control severe diarrhea. Symptoms should improve and resolve in a few days. If they don't or if they worsen see your physician for evaluation.
