question: My granddaughter is in the ER with severe stomach pains. She has had these pains for quite a few weeks. Now she is vomitting green bile, has not had anything to eat in 24 hours as she can t keep anything down. She is also dehydrated. Doctors said to follow up with a gastroenterologist. She cannot stop vomitting etc and they want to send her home. this doesn t make any sense to me. She graduates in 5 days and can t even stand up. What could be the problem as the ER doctors don t seem to be doing anything to help her.
