Patient's question:
Recently, I've been experiencing chest pain and tightness in my chest. The hospital examination suggested a respiratory disease, but the medication hasn't been very effective. Recently, my cough has worsened. What are the symptoms of a lung infection?Doctor's answer:
Pulmonary infection refers to the inflammation of the terminal airways, among which pneumonia is more typical and representative. Clinically, it may present with difficulty in breathing, changes in body temperature, coughing, increased sputum volume, and changes in sputum characteristics. These changes could be caused by viral influenza, or they may be secondary bacterial infections that trigger bronchitis or pneumonia. Pulmonary infections are often caused by exposure to cold, bacterial infections, or viral infections leading to inflammation of the lungs.
