Painful Diarrhea: If you are having diarrhea that is painful or having pain that is moving around, it may not be a simple condition. You should check to see if you are having fever, if there is blood in you stool, or if there are other concomitant condition. You should probably see a doctor to rule out condition such as inflammatory bowel disease. http://www.laendo.net/english/inflammatory-bowel-disease-88079022.
