I am Chat Doctor answering your query. If I were your doctor, apart from a detailed clinical examination, I would have advised you for an ultrasound of abdomen, some blood tests like CBC, serum amylase and lipase, blood urea, serum creatinine, blood sugar, and a routine/microscopic test of the urine. Till the reports come, I would prescribe you a proton pump inhibitor, an anti-emetic, and a probiotic Chat Doctor.  I would also advise you not to have food from outside and avoid consuming alcohol/smoking if you do. Further management would depend on the investigation reports and the physical examination. 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 Chat Doctor to clear doubts on your health problems. Wishing you an early recovery. Chat Doctor. </s>
