The organism is easily mistaken about stomach pain and liver pain, the two kinds of pain. There is a certain gap between the location of pain in liver pain and stomach pain, as well as the nature of the pain, which can be roughly judged by the following ways. The location where stomach pain is located is usually around the navel as well as upper abdominal pain. The pain characteristics of stomach pain are mostly paroxysmal pain, but there are also special pains, and patients who show gastric perforation may show persistent sharp knife-like pain, and the symptoms of pain around or above the navel when pressing on the stomach pain will be more severe. Liver pain is manifested in the right upper abdomen with vague pain. This pain is manifested as persistent pain and worsens when local pressure is applied. For patients with frequent stomach pain or liver pain, it is recommended to go to the hospital for liver and biliary ultrasound and gastroscopy to determine what the organ of pain is and to take appropriate treatment.
