My daughter has been diagnosed with GERD but has had it under control. However, a week ago she was complaining about stomach pain in her upper abdomen. It seemed to go away, but has come back even stronger. She's 16 and has been puking for two days. None of the meds seem to work. She has zofran, omnerprazole, and dicyclomine but nothing seems to help. Every time she gets up, she has to puke. What should we do?
