For last 2 days i am feeling bloating in my stomach and today i am having pain in my chest in same place where my gall bladder have been removed also sour vomiting and its still paining [/INST] Hello, At first I would suggest you never to skip meals. With a history of cholecystectomy (gall bladder removal) 3 years back and suddenly having bloating and pain, you must get yourself evaluated for biliary obstruction possibly due to common bile duct stones, which needs to be ruled out firstly. Then other causes like infection need to be suspected. Please consult your surgeon and get blood test and ultrasound abdomen done. Hope this helps. </s>
