If a fracture of the sternum occurs, the most obvious symptom is a painful symptom in the local fixed position of the injury. Some fractures that are less irritating to the surrounding soft tissues may be less painful without excessive movement of the chest, while movements of the chest, such as lying down in a sitting position, turning over and getting up, deep breathing, coughing, sneezing, etc., may cause a significant increase in pain symptoms. In some cases, the pain may be more pronounced even when the patient does not move the chest, and the movement of the chest may be significantly restricted, and the patient may not dare to do any movement of the chest. The majority of patients experience severe pain with pressure on the injury, and some patients experience localized swelling. There is a big difference between a sternal fracture and a sternal fracture in terms of the degree of injury, as a sternal fracture is not particularly serious, while a sternal fracture has a high risk of serious symptoms.
