Hello I have a medical question. For about over a year now, everyday i gag and almost puke and burp constantly, anything i eat or drink triggers pain, leaves bad tastes like sour stomach type of feeling. gas a lot of the time, and constipation. lower left side of stomach constantly inflamed. i cannot move on my left side or it gets extreme pain. sleeping on the left side makes symptoms worse also. i have recently noticed about 20lb. weight loss in a few weeks, usually tan but turning pale.
