Hidden pain in the right posterior axilla of cirrhotic patients may be an exacerbation of cirrhotic disease or a combination of biliary tract diseases such as gallbladder infection, cholelithiasis, hepatocellular carcinoma, costochondritis, and so on. Cirrhosis is the end stage of various chronic liver diseases (e.g. viral hepatitis, fatty liver, etc.) and is usually accompanied by pain in the right upper abdomen. The right posterior axilla is located above the right upper abdomen, and pain here may also occur if the patient’s condition is further aggravated. If cirrhosis is accompanied by biliary tract diseases such as cholecystitis, gallbladder stones, bile duct stones, etc., the patient may experience right upper abdominal colic during the attack of the disease, which also radiates to the back and shoulders, and may also feel a vague pain in the back of the right axilla. If the patient develops cancer on the basis of cirrhosis and develops liver cancer, he/she may experience cancerous pain, which involves the back of the right armpit, causing the patient to feel hidden pain in the back of the right armpit. Patients with costochondritis may also experience vague pain in the right posterior axilla at the onset of the disease. If patients develop costochondritis along with cirrhosis, they may also feel vague pain in the right posterior axilla. If patients with cirrhosis experience pain in the right posterior axilla, it is recommended that they consult a doctor in time to find out the cause of the disease and receive treatment actively so as not to delay their condition.
