Since the gastrointestinal tract in the abdominal cavity is jointly innervated by sympathetic and parasympathetic nerves, and may be affected by emotions, such as anger may lead to an increase in intestinal peristalsis, manifesting abdominal pain, usually transient pain or paroxysmal pain, after rest or massage and hot towels, the pain can usually be relieved on its own, which is a normal phenomenon. If the patient has frequent abdominal pain or pain of a very intense nature, and the pain does not ease for a long time, consider that a lesion may have occurred in the abdominal cavity. If necessary, abdominal CT or gastroscopy or colonoscopy can be done to further clarify. If all the test results are normal, it means there is not much problem. If it is considered to be a tumor in the stomach or colon, it is necessary to perform radical surgery.
