Hi! Good afternoon. I am Dr Shareef answering your query. If I were your doctor, I would advise you not to eat from outside if you do, as intestinal infection could creep in from outside food and give rise to such pain in the abdomen. Also restrain from alcoholic beverages if you do consume these. I would also examine you physically and advise some investigations like a complete blood count, an liver function test, a serum amylase and lipase, and an ultrasound of the abdomen to rule out chances of any gallstones and pancreatitis. Till then you could go for a proton pump inhibitor along with an anti spasmodic drug for a symptomatic relief. 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. I wish you an early recovery. Dr Shareef.
