Doctor, since last three years in got severe pain in the upper part of stomach (totally three times, like once in a year). This time i got paing in April'13th. I Went to a gastroenterologist , did scopy and US scan, the impressions was antrum gastritis and gall stones. Dr said he need to remove my gall bladder. But, i feel the pain may be due to the gastritis problem, if it is so, it is not required to remove the bladder. How do i confirm where the pain in due to gastritis or stone? please help me with clear details
