I have had extreme nausea the last couple of weeks and since yesterday have had severe a pain in my upper abdomen below by breast plate, has blood tests a few weeks ago that were positive for I think IGG and some other bacteria, have been on tums, nexium for the last 2 weeks also, feels like I need to burb really bad but cant, scope and colonoscopy scheduled Apirl 14 but don t think I can be this uncomfortable for that long. What should I do?
