Hi ! Good evening. I am Dr Shareef answering your query. This could be due to some kind of food poisoning if you ate from outside your home. I am not aware if you do smoke or drink. In that case you should get an ultrasound done and some routine blood tests along with a serum lipase and amylase to rule out pancreatitis and gall stones. If I were your doctor, I would advise you for an ultrasound abdomen followed by a CT if need be. However, all this would be preceded by a physical examination and some other investigations if need arises. Till this time, you can go for a proton pump inhibitor drug, a probiotic, an anti spasmodic if advised by your treating doctor. 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.
