Thank you very much for your reply and your kind words. They think that I have had the collapsed lung for a very long time. I have had four bouts of pneumonia with the first at 4 years old which caused the bronchiectasis and damage which made the lung collapse. On my CT scan in May, the radiologist that read the scan commented that it served no respiratory purpose and was actually a harboring place for recurrent infections. My infectious disease doctor said that the National Jewish Health in Denver, Colorado is the world's leading respiratory foundation and is the only place that he would send me.
