Chest tightness after hunchback correction may be related to the corrective posture, or it may be caused by heart disease, respiratory system disease, etc. 1. Corrective posture: long-term hunchback will compress the respiratory muscles, such as diaphragm, abdominal muscles, intercostal muscles, etc., so that these muscles are in an incorrect position for a long time. Therefore, after the correction of hunchback, the respiratory related muscle groups are pulled and their functions are decreased, therefore, dyspnea may appear briefly. 2. Heart disease: common in coronary heart disease, easy to cause dyspnea, the decline of activity tolerance is a typical symptom of cardiac anomalies. There are no obvious symptoms when you are inactive, but when you walk, go upstairs or move a little, you may feel tightness in the chest and have dyspnea. 3. Respiratory diseases: some people have chronic obstructive pulmonary disease (COPD), which is an abnormality of the lungs or airway ventilation, and gas exchange obstacles, which may lead to dyspnea and hypoxia, resulting in chest tightness. When chest tightness occurs after the correction of hunchback, it is recommended to consult a doctor in a timely manner, follow the doctor’s instructions for further examination, after a clear diagnosis in the doctor’s comprehensive analysis, choose a reasonable treatment plan, so as not to delay the condition.
