A dry, non-sputum cough is normal during the recovery period of pneumonia because pneumonia is mainly characterized by varying degrees of congestion and edema of the alveolar mucosa, as well as exudation of inflammatory secretions. After active anti-inflammatory treatment, the pathological state is controlled and reduced, but it does not fully return to the normal mucosal state. The inflammatory reaction of congestion, edema, and exudation of secretion, the mucosa needs further self-repair and a process is still needed, and the symptoms of dry cough will still appear. At this time, it is important to keep warm, avoid getting cold, and avoid re-infection with other pathogens. If necessary, you can take appropriate medications to clear the lungs and resolve phlegm, such as Nourishing Yin and Clearing Lung Pills and Lantern Leaf Granules. You can also do nebulization, such as choosing budesonide nebulizer, to promote cough relief.
