Hi, I have been bloating more for last 6 months. Which I can call not usual compare to earlier year. I am getting pain on left side of chest when sleeping,as per physician suspect it is due to gas in stomach. The pain is not continuous it goes and comes back. Sometime I do not get good sleep due to chest discomfort when lying on bed. History : My gallbladder removed by lap surgery 6 years ago. At the same time Endoscopy was done for stomach and mild hital hernia was detected. Please advice ?
