Occasional stabbing pain in the liver area for one or two seconds is mostly due to physiologic factors, but diseases of the hepatobiliary system and chest diseases also need to be excluded. As the liver parenchyma itself does not have nociceptive nerves, only when the lesion stimulates the hepatic peritoneum, pain will occur, and the common hepatobiliary diseases such as cholecystitis, cirrhosis, etc., resulting in pain is mostly severe and persistent, the occasional stabbing pain for one or two seconds need to pay attention to whether it is intercostal neuralgia or thoracic diseases. In addition to pathologic factors, if you have been doing too much strenuous exercise, staying up too late, drinking too much alcohol, or eating spicy and irritating food, it is possible that your liver may be in physiological pain due to irregular diets and work schedules. It is recommended to consult a regular hospital for relevant examinations, such as liver CT, abdominal ultrasound, chest CT, liver function, hepatitis B series, etc., for differential diagnosis.
