### Patient: Doctor, I have been having severe headaches and nasal congestion for the past few days. I also have a fever and my face feels very tender. I think I might have acute sinusitis.
### Doctor: Okay, based on your symptoms, we need to perform some diagnostic procedures to confirm the diagnosis. We may need to do a CAT scan of your head and an Influenzavirus antibody assay to rule out any other conditions. Additionally, we may need to evaluate you further and consider other respiratory therapy or physical therapy exercises to help you feel better.
