A 67-year-old man comes to the Chest Clinic after being referred by his GP for a chronic cough. He complains of a dry cough that has been ongoing for 10 months and is accompanied by increasing shortness of breath. Despite multiple rounds of antibiotics, he has not experienced significant improvement. He has never smoked and denies any coughing up of blood.
