Hi ! Good evening. I am Dr Shareef answering your query. If I were your doctor, I would first advise you not to eat anything from outside specially the fast and fried food. This might cause hyper acidity and pain in your stomach. Next I would suggest you to go for some routine blood examinations like a cbc, serum amylase, and lipase, a stool test for ova, cyst and occult blood, and an ultrasound/CT scan if need be. Further management would depend on the result of the investigations. Till then you can go for a proton pump inhibitor, an antacid gel, a probiotic, an anti spasmodic if too much of a pain, an anti amebic depending on the report of the stool test. 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.
