The location of abdominal pain caused by inflammation of the duodenum or duodenal erosion or duodenal ulcer is mostly on the left side of the abdomen, and it is in the left upper abdomen or in the upper abdomen below the glabella, and the pain on the right side of the abdomen rarely occurs, but of course, the existence of special cases is not excluded. However, when patients have right-sided abdominal pain, they should first rule out problems of the biliary system, such as acute cholecystitis, chronic cholecystitis or liver disease. It is recommended that patients should go to the hospital if necessary, and cooperate with the doctor to check abdominal ultrasound or upper abdominal CT, and further improve the electronic gastroscopy if necessary. If biliary system diseases are clearly present, the patient should be treated with anti-inflammatory and biliary drugs in cooperation with the hepatobiliary surgeon. If it is clear that the digestive system diseases, you need to cooperate with the doctor to give the use of acid-suppressing and stomach-protecting drugs, etc., the specific medication need to consult the specialist.
