Suggestion: Hello, considering the possibility of bronchitis or pneumonia, it is recommended to do chest X-ray and blood routine examination. If bacterial infection is considered, it is recommended to use antibiotics for anti-infection treatment, such as cephalosporins. It is best to do sputum culture and drug sensitivity test, and then choose sensitive antibiotics according to the drug sensitivity results. At the same time, antitussive drugs such as ambroxol are added.
