recently I had a stomach bug. It lasted for about 5 days, and consisted of extreme diarrhea, gas, and nausea (no vomiting). Ever since then I have had abdominal cramps, gas, sometimes acid reflux, and have had to use the bathroom a lot more often than usual. Lactose products make me feel worse, but if I eliminate lactose from my diet the symptoms don’t completely go away. It has been two months since I originally had the stomach virus. does anyone know what could be wrong.
