No treatment suggested yet. I was Dx with MAC & Bronchiectasis first. Chest tightness (which happens sporadically and without defined triggers) came later.
It came along insidiously without me realizing what it was if that makes sense. No other asthma symptoms now or before. That's why I wondered if it's the inflammatory nature of the MAC itself that could be the cause of the airways / chest tightness?
I do have an "abnormal" spirometry. Spirometry is the only test I know of that is done for asthma. Which that seems odd to me since abnormal could indicate other obstructive disease also.
