Pain in the upper part of the chest is seen for many reasons: 1. Hypertensive disease, which can appear as aortic dilatation, or in severe cases, aortic aneurysm or entrapment, patients will experience chest pain. Common pain medications cannot be controlled, and an enhanced CT examination can confirm the diagnosis, and interventional therapy is required if necessary. 2. Some patients have diseases occurring in the mediastinum of the thorax, mainly occupying lesions, specifically two diseases and malignant tumors. The pain of malignant lesions will be more pronounced and will also manifest as an anterior chest bulge and even a significant loss of appetite. In addition, metastases of the thoracic cavity and mediastinal lymph nodes are likely to occur, and pressure on the trachea or esophagus may also lead to coughing, coughing up sputum, difficulty in eating, or the occurrence of uncomfortable symptoms such as significant coughing up of sputum with blood.
