Liver cancer right shoulder pain is located at the shoulder joint. Right shoulder pain of liver cancer patients is usually caused by liver cancer located below the diaphragm on the right liver surface invading the diaphragm on the right side. Right shoulder pain caused by liver cancer does not affect shoulder joint movement and is usually combined with hidden pain in the upper abdomen, only that sometimes the radiating pain in the shoulder is more intense to cover up the pain in the abdomen, and the use of massage and physiotherapy and other methods can not relieve the symptoms. Generally speaking, the radiating pain in the shoulder occurs when the mass is located under the liver pericardium and invades the diaphragm or phrenic nerve, while small liver cancers or masses located deeper in the liver usually do not have this symptom. The pain caused by visceral lesions is not as accurate as the pain on the surface of the skin, which is often the damaged part of the skin, while the visceral lesions will cause reflex pain and involving pain, and the site of pain may not necessarily be the site of the lesion. It is suggested that liver cancer patients should go to regular hospitals for consultation and systematic diagnosis and treatment according to the advice of specialists.
