Hi ! Good evening. I am Dr Shareef answering your query. Even though it might not be possible to pin point the problem without a physical examination, if I were your treating doctor, I would after a physical examination possibly would go for some tests like a complete blood count, a serum amylase and lipase estimation, liver function test, and an ultrasound of abdomen if need be to rule out any intra-abdominal pathology. Till then, I would prescribe you with a proton pump inhibitor drug, and also deworm you as a routine procedure. 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.
