Hi! Good evening. I am Dr Shareef answering your query. It is possible that few drinks every night might have caused inflammation of the gastro-duodenal mucosa causing gastritis/duodenitis giving rise to the severe stomach pain and cramping. Also it could have been due to some kind of food poisoning as you must be eating outside during your holidays. If I were your doctor, I would first discourage your alcohol intake at least till you become ok, and also prescribe a proton pump inhibitor, a prokinetic drug, and a probiotic.This should relieve you of your symptoms. I would also like to know if you are married or are sexually active. In that case I would also advise you for a serum HCG, and an ultrasound to rule out any chance of a pregnancy. 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.
