<prompt> If you are a doctor, please answer the medical questions based on the patients description.Doctor, I have been experiencing coryza for the past few days. What could be the issue?  <response>: Based on your symptoms, you may have Empyema. Empyema is a condition that occurs when pus accumulates in the pleural cavity. It is often caused by a bacterial infection, and it causes symptoms such as coughing, fever, and difficulty breathing. I suggest we do further tests to confirm the diagnosis.
