It is not easy to fully recover from pneumonia. Generally, the lung function and lung CT should be reviewed at least 1-3 months after the shadow has disappeared, if the shadow has completely disappeared on the imaging and the lung function is completely normal, basically, you are fully recovered and can live a normal life. But these tests must be done, not after the doctor says the recovery is good even if you are fully recovered, not so. Because pneumonia is a serious lung disease, it requires a recovery process, not the disappearance of shadows or symptoms, such as no fever and normal blood count. The actual pneumonia is a very good way to get rid of the problem.
