Pain in the back can also be treated by visiting a thoracic surgeon or registering with an orthopedic surgeon. The common cause is periarthritis of the shoulder or cervical spondylosis, which is related to exertion, especially after weight bearing. The patient should pay attention to rest, can be given appropriate pain medication, and if necessary, can also be localized DR film or CT and other related examinations. In addition, some patients are caused by diseases occurring in the thoracic cavity, which commonly include intrapulmonary infections, lung nodules and lung tumors, and need to go to the thoracic surgery department to further improve the chest CT and other related examinations. For simple infections, anti-infective treatment can be chosen. Tumors occurring in the lungs can be treated with surgery if the condition permits, and malignant diseases are the most common. These diseases are closely related to smoking, so you should stay away from the environment of tobacco in general.
