Under normal circumstances, the abdomen is symmetrical between the left and right side. If one side of the abdomen is higher than the other, first of all, we should consider whether there is a local infectious lesion, and it is recommended to go to a regular hospital for examination by a doctor. If there is obvious pressure pain and rebound pain in the right side of the abdomen and there is fever in the body, then it may be caused by hepatobiliary disease, which requires abdominal ultrasound and blood tests to clarify the examination, and if the diagnosis is clear, antibiotic anti-infection treatment is needed.
