Hi ! Good morning. I am Dr Shareef answering your query. For the present, you could give him an anti spasmodic, a proton pump inhibitor and a probiotic drug as an immediate measure. However, I would advise you to get him assessed clinically by your family physician for a proper diagnosis, and appropriate treatment. 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.
