I have been having constant belching, loss of appetite, right sided stomach pain, dehydration, constant heart palpitations, steady weight loss, and constant heat flashes for 11 days straight. I had went to the ER twice and had Urine Test, Chest X-Ray, EKG, CBC and Differential, CT ABD and Pelvis W Contrast, Comprehensive metabolic panel, and Lipase Blood test done. All came out good. The general doctors think it is a stomach virus except I am not vomiting, no fever, no diariahia, nausea on very rare occasions, and no fatigue.
