My Daughter Is 25 And In NYC. She Has Had

My daughter is 25 and in NYC. She has had pain/ cramping in her intestinal area since about 2 am. She has tried drinking tea, she can't eat. She said it is painful. I just convinced her to go to the emergency room at Beth Israel and is there. We were with her this weekend. We all ate the same food, etc, so don't feel it's food poisoning. Amy ideas?
