My symptoms: water diarrhea, rectum pain, left abdominal pain, bellybutton tender, fainted, extremely bloated, lower pains and lightheaded/ringing ears ?

Doctor can evaluate: Stomach aches plus diarrhea can be from a variety of causes. People usually see doctors if symptoms are bad or if they last more than 1-2 days. When diarrhea first starts happening, a person can benefit by stopping eating and start just drinking small amounts (2-3 ounces) of something like Pedialyte or half-strength Gatorade, hourly for a day. Fainting or extreme bloating means one needs a doctor.
