A friend of mine has been complaining of stomach pains for the past week. The pain increases when she eats. It is mostly on the left side of her abdomen. Then she spends a substantial amount of tie in the bathroom with increased pain and releases loose stool that is mixed with a white mucus rectal discharge. I have a feeling this is serious but her parents wont admit her to see a doctor unless they're presented with some info. What are the possibilities of diseases and diagnostic tests with these symptoms.
