In the past week, anything that I eat or drink makes the top left portion of my stomach very diet. My abdomen is very bloated and tight. I am passing gas, have had bowel movements daily, drinking plenty of fluids and I am no tpregnant. Also have been nausea through out the day and middle of night and constantly burping. The middle of my stomach is so tight and its difficult to even eat a bite of food, although I am starving.
