During the recovery period of pneumonia, there is a sound in the lungs but it will disappear after spitting. Consider that the sputum is blocking the airways and the pneumonia has not completely dissipated. 1. The course of pneumonia usually lasts for about 1-2 weeks or even longer. After entering the recovery period of pneumonia, as the inflammation of lung tissues has not completely subsided, there are still secretions in the airways, resulting in sputum clogging the airways, and the situation of voices in the lungs disappearing after spitting may occur. 2. If there is still a sound in the lungs in the recovery period of pneumonia, you need to continue to carry out effective anti-infection treatment, you can follow the doctor’s instructions to use penicillin or ciprofloxacin, but also need to use aminoglutethimide, acetylcysteine and other phlegm medication for symptomatic treatment, and at the same time, you need to rest and pay attention to the diet of light.
