@desperate2 You've come to right place for thoughtful discussion and guidance. First off, @cwal asks pertinent questions, probably the 2 most important are about airway clearance and if your pulmonologist is a NTM specialist.

Here's a link a to information, scientific papers and other up-to-date materials on NTM and bronchiectasis. You might want to spend some time there as general pulmonologists do not have knowledge, training or experience about bronchiectasis let alone NTM disease. As a fellow sufferer it's crucial to be an informed patient.
