Hello, If there is upper intestinal edema, then usually the bloating of the abdomen is common. Kindly get an upper endoscopy done to rule out any condition. Get one ultrasound done to know if there is any other pathology of the abdomen. Use gastric tablets like ranitidine, pantoprazole or omeprazole before food for 15 days and see if your problems subside. If you still have pain I prefer you to go to a surgeon for a general examination. Hope I have answered your query. Let me know if I can assist you further. Regards, Dr. Archana
