Pain in the lungs like a fork in the air is not excluded as a result of spontaneous pneumothorax. In particular, some patients who are older and have smoked for years will have recurrent coughing and wheezing, that is, they have chronic obstructive pulmonary disease, the chest cavity will form adhesions with fibrous strips or pulmonary fibrosis, and after the pneumothorax, the patient will show chest pain and chest tightness, and the lung tissue will be locally stretched, and the patient will show obvious pain. Pneumothorax is a disease that requires surgery for drainage if necessary. You should also pay attention to stay away from smoking and alcohol consumption, take appropriate respiratory exercises to enhance physical fitness, and avoid strenuous activities, such as coughing or strenuous exercise, which can easily lead to local lung tissue rupture, especially the rupture of pulmonary blisters and the occurrence of pneumothorax.
