Definitely agree with the responses here. If you can get to a pulmonologist or infectious disease dr with MAC/bronchiectasis experience they will help you. There is a lot of advice on these threads for finding a good doctor. And getting a referral to a respiratory therapist or chest therapist who can help you learn airway clearance techniques was almost as important for me as getting the right doctor. I was nebulizing saline without much training and getting hardly anything until I had chest therapy.
