In men, most of the two sides of the stomach are the location of the colon, the right side is the ascending colon, and the left side is the descending colon, so pain occurs on both sides: first, consider the pain caused by intestinal spasm due to intestinal dysfunction or acute infection of the intestine. Secondly, consider whether there is intestinal obstruction, which may also be accompanied by vomiting and other symptoms. For elderly people, they should also be alert to the presence of intestinal tumors, and when pain occurs, they should also observe whether there is abdominal distention or defecation dysfunction, as well as the presence of black stools. Finally, because there are also ureters on both sides of men, it is also important to consider whether there are ureteral stones or cysts in the kidneys or kidney stones. Therefore, in order to clarify the cause, it is best to seek medical attention and further improve the examination to confirm the cause and timely treatment.
