@cwal Asthma and Bronchiectasis often go together.
I was diagnosed with asthma at the age of forty, but realize I probably have had it since about the age of 11 or 12, around the same time I regularly began suffering from pneumonia and sinus infections. Silly me - I had two asthmatic kids and two nieces, and I never connected my symptoms with theirs because my "triggers" were different.
I learned that asthma and pneumonia (either one severe case or a number of infections) can often be predictive of developing bronchiectasis.
Others are like you, suggestion comes during treatment for MAC and or Bronchiectasis.

Here was a game-changer for me -my pulmonologist decided my Asthma was primary - chest tightness, shortness of breath - and Bronchiectasis secondary. Since I did not have any active MAC or other infection, she started me on a med originally for COPD, Symbicort. It contains formoterol, a long-acting beta-agonist (LABA) that opens airways like albuterol or levalbuterol, but is effective for 10-12 hours instead of 2-3. Yes, it contains a corticosteroid, but there is a formulation with a very low dose, and so far has not caused me any problem.

What treatment has been suggested to you?
