I was diagnosed with Bronchiectasis and MAC in 2017. The Doctors I went to said to do nothing. They did a CT every year and said do nothing until 2022. By then I had lost some pulmonary function. I wish I had know about airway clearance in 2017. If I had been doing it since 2017, I would not be having the problems I am having now. Go to NJH and get a baseline and start air way clearance and you won’t have to worry about it getting worse.
