Hello, my girlfriend is experiencing a feeling of nausea and a stabbing feeling in her stomache, she has gone poop 11 times today, it is 3:00 PM where I am, and she woke up around 10AM. Nothing is coming out anymore just water. Whats wrong does she need to go to er? She has always had a very minor degree of lactose intolerance and ate a cheese quesidilla with sourcream on it yesterday, is it possible that her intolerance has gotten worse?
