The liver is mainly located in the right upper abdomen, adjacent to the right posterior back, and when a patient develops cirrhosis, it can manifest as pain in the right posterior back. Cirrhosis is mainly caused by hepatitis B virus infection, which leads to rupture, rupture and necrosis of hepatocytes and formation of pseudo lobe, inducing damage to hepatocytes, and it is mostly irreversible. At this time, due to the obstruction of venous return caused by cirrhosis, gastroesophageal vein dilatation causes upper gastrointestinal bleeding, presenting obvious right back pain. When hepatocyte damage occurs, right back pain is also manifested. In addition to the above symptoms, patients with cirrhosis may also experience other discomforts such as nausea, vomiting, dyspepsia, lethargy, gastrointestinal bleeding, and hypoproteinemia. When discomfort occurs, patients are advised to seek timely medical attention and active treatment to avoid delaying the condition and causing further progression of cirrhosis.
