The location of right shoulder pain of liver cancer is usually around the clavicle and shoulder joint. The main reason for right shoulder pain in liver cancer patients is due to the gradual enlargement of liver tumor, which presses the nearby diaphragm and also presses the muscle nerves below the lungs. And these pressed nerves happen to be the nerves connecting the right shoulder, which will lead to the appearance of right shoulder pain. If the patient’s tumor involves the diaphragm, the symptoms of pain will be more obvious. With the development of liver cancer, the patient will also have obvious anemia, hypoproteinemia and ascites, etc. The patient will also have obvious abdominal distension and pain and irregular low-grade fever, and a large amount of ascites restricts the movement of diaphragm, so the patient will have obvious pain in the chest, and in serious cases, it will lead to respiratory difficulties and other symptoms. For patients diagnosed with early stage of liver cancer, surgery should be actively carried out, while patients diagnosed with advanced stage of liver cancer can control the development of the disease through auxiliary interventional therapy, and pain relief drugs can be given as prescribed by doctors when necessary.
