More likely: the diarrhea and nausea are causing dehydration which then makes you feel worse. The sensation many people get when you feel like you are going to vomit does involve the upper abdomen and chest. Most important is to try to get some fluids/water into you now. Actually retching or "dry heaving" can also be a sign of acid reflux or anxiety. Hope you start to feel better soon:)
