39 asian female, menses Nov 6-12, abdominal pain LLQ goes away when supine, tender to touch, no fever, ate (stupidly) at Burger King Mon evening. Onset next morning, vomiting. No diarrhea. Some bloating, + flatulence and last BM Monday. At Disney world for the week. Seem to walk ok, occasional cramping. Nothing that brings me to my knees. Back pain because I am walking in flip flops, perhaps? Have one day left (today) and headed home tomorrow morning. Warrant an ER visit? Pain tolerable with Motrin.
