Some lung infections may clear up on their own, but it is advisable not to wait for them to clear up and seek medical attention as soon as possible. Lung infection refers to pneumonia caused by pathogenic microorganisms and is the most common form of pneumonia and one of the most common infectious diseases. Some pneumonias are self-limiting, such as Mycoplasma pneumonia, which may resolve spontaneously with insignificant clinical symptoms in mild infections, and Chlamydia pneumonia, which may resolve spontaneously without treatment in most cases. However, there are many pathogens that can cause lung infections, and most of them need active anti-infective treatment, otherwise they may cause serious complications such as pyothorax and lung abscess, and some severe pneumonias may even be life-threatening. Therefore, it is recommended that you do not blindly wait for it to heal, and go to the hospital for examination in time to clarify the cause of the disease and then treat it under the guidance of the doctor. `
