Last December I fell something is blasting in my stomach and fell burning in my stomach and chest everywhere. When I go to hospital doctor says it's gas. After when I discharged from hospital I fell very uncomfortable and fear. I go to Hyderabad where my all reports are normal but till I have facing acidity bloating and sometimes burning in my stomach as well as chest what is the reason? I am very heavy smoker but I left smoking in last December is this cause due to left smoking or anything else? Please gave me any suggestions.
