My 17 yr old daughter was just diagnosed with Crohn's. She's taking Pentasa and Prednisone. The last few days shes had a bloated/destended belly that seems to happen mainly at nigjt and is a bit painful even to the touch. This morning she vomited and her stomach hurts her. She has a cramping feeling. Could this be a blockage, should I be worried? I couldnt get in touch with her Dr yet. Next appt isnt for two weeks. Any insight would be much appreciated. Thanks
