Lung blisters that have the potential to become more severe with each passing year. Pulmonary pustules are air-containing saccular cavities larger than 1cm in diameter formed by the fusion of alveoli with each other after the pressure inside the alveoli rises and the alveolar walls rupture due to various reasons, and many patients are accompanied by lung underlying diseases such as emphysema, chronic bronchitis, and tuberculosis. If the patient is young and healthy, without related basic lung diseases, the pulmonary blisters usually do not gradually aggravate, and can be left untreated, but attention should be paid to avoiding sudden and strenuous activities in daily life, so as to avoid spontaneous rupture of the pulmonary blisters. If the patient is older and combined with the above mentioned underlying lung diseases, because of the progression of the lung diseases, it may cause further development of the original lung pustules, or the emergence of multiple lung pustules, which will make the lung pustules gradually aggravate, resulting in chest tightness, shortness of breath, chest pain, hemoptysis, co-infections, and spontaneous hemopneumothorax, and so on. After the diagnosis of pulmonary herpes is confirmed, it is necessary to go to a professional medical institution, actively treat the underlying disease that causes pulmonary herpes, and if the pulmonary herpes is serious, it may need early surgical treatment.
