Hi! Good evening. I am Dr Shareef answering your query. From your history, it seems to be a colic type of pain due to a stone in gall bladder or CBD, an attack of pancreatitis (specially if you consume any alcoholic beverages. Whatever it could be, this needs to be worked up with proper clinical examination at the time of attack and related investigations like a complete blood count, a liver function test, serum amylase and lipase, and an ultraound/CT scan of abdomen if need be. So you have taken the right decision of going to the ER for proper management. I hope this information would help you in discussing with your family physician/treating doctor in further management of your problem. Please do not hesitate to ask in case of any further doubts. Thanks for choosing health care magic to clear doubts on your health problems. Wishing you an early recovery. Dr Shareef.
