Hi ! Good evening. I am Dr Shareef answering your query. If I were your doctor, I would have first done a physical examination of your abdomen, followed by some blood tests like a complete blood count, a liver function test, a serum amylase and lipase, blood sugar, urine routine and microscopic, and possibly an ultrasound to rule out gallstone disease/pancreatitis which could give rise to such excruciating pain in abdomen and back. Also in the history, if you consume alcoholic beverages and do smoke, then I would insist on complete abstinence from both as both could cause pancreatitis. Till the reports are ready, I would advise you to adhere to a bland diet, and avoid any oily,fried and spicy food, and prescribe you with an anti spasmodic and a proton pump inhibitor 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.
