“My wife says I need to get my lungs checked. Ever since we moved, I’m having a hard time breathing.”
Dwayne Morrison is a 59-year-old man who is presenting to a new provider at the family medicine clinic today with complaints of increasing shortness of breath. He points out that he first noticed some difficulty catching his breath at his job 3 years ago. He had been able to carry heavy loads up and down a flight of stairs daily for the past 35 years without any problem. However, his shortness of breath began to make this very difficult. Coincidentally at that time, he accepted a managerial position at his company that significantly reduced his activity level. After taking this position, he no longer noticed any problems, but he admits that he avoids activities that cause him to physically exert himself. He noticed significant shortness of breath again after he moved to Colorado from a lower elevation 2 months ago to be closer to his grandchildren. His shortness of breath is worst when he is outside playing with his grandchildren. He maintained his same managerial position with the move and does not physically exert himself at work. His previous physician had placed him on budesonide/formoterol (Symbicort) two inhalations twice daily 2 years ago. He thinks his physician initiated the medication for the shortness of breath, but he is not entirely sure. He is hoping to get a good medication that will help relieve his shortness of breath because the gardening season is right around the corner, and he enjoys this hobby.
