If pain occurs in the right side of the chest and back, first of all, it is necessary to clarify whether there are any fatal diseases, especially aortic aneurysm diseases in the chest and abdomen, including aortic aneurysm and aortic coarctation in the chest and abdomen, and it is necessary to actively improve CT angiography for clarification, because this disease may not have obvious symptoms, but the mortality rate is really quite high, and it is necessary to actively carry out prevention as well as treatment. Pain in the right side of the chest and back may also be caused by internal diseases, such as inflammation and stones in the liver, gallbladder, or even tumor diseases, which may cause pain in the right side of the chest and back through the involvement of some internal nerves. Septic infectious diseases of the lungs, as well as pneumonia and tumor diseases of the lungs, may cause pain in the right thoracic back. However, in most cases, right thoracic back pain is caused by poor living habits and working posture, such as prolonged head bowing, waist bending, repeated rotation of the chest, and prolonged repetition of a certain posture and movement, all of which can cause local soft tissues to be stretched repeatedly, resulting in local congestion and edema, forming a sterile inflammation and leading to pain.
