Been having abdominal bloating. Not being able to pass gas or burp. Feels like I have to throw up. Plus have a sore throat. Please help?

Gas. If you feel that gaseous buildup in your stomach or intestinal tract is a problem, drinking warm water and/or applying a hot water bottle to the abdomen helps break down the gas and moves it down for passing. Taking simethicone after meals prevents gas build-up. The sore throat may well be part of a viral infection, but if it worsens have a throat culture to rule out strep.
