Clinically it is a manifestation of a snapping pain in the liver area, below the right rib cage which is the site of the liver and gallbladder, and also in the right upper abdomen. Snapping pain is a physical tool often used in clinical practice to examine the abdomen, which we call percussion pain, and is significant in the diagnosis of liver disease. Positive percussion pain indicates that the patient may have liver diseases such as hepatitis, hepatocellular carcinoma, liver abscess, etc. Also in combination with tapping pain below the right rib cage, the patient will be given laboratory tests such as routine blood tests, hepatitis series, liver function, and kidney function. Ultrasound or CT examination of the abdomen should also be performed to determine whether the right upper abdominal liver and gallbladder have corresponding diseases and to further clarify the disorder of positive percussion pain in the liver area.
