Pneumonia can cause nasal congestion. Pneumonia itself is an inflammatory disease, caused by bacterial or viral infection. Bacteria can pass through the respiratory mucosa and reach the nasal mucosa from the lungs and multiply in the nasal cavity, causing edema of the local mucosa, resulting in local secretion obstruction and causing symptoms of nasal congestion. If nasal congestion occurs, parents should not worry, they can apply medications, such as pediatric aminophenanthrene granules, anti-sensory granules, etc., which can relieve nasal congestion and achieve the purpose of treatment. In addition, if the secretions are more and more dry, you can use a smaller cotton swab with sesame oil or water to moisten the child’s nasal cavity so that the airway is open and the pneumonia will slowly recover.
