This seems to be typical. Unless you are already diagnosed with bronchiectasis, MAC is not something the docs think of until everything else fails. My own diagnosis took over 2 years of repeated illness and coughing with numerous rounds of prednisone and antibiotics. Then 2 months to control pseudomonas and 18 months of MAC antibiotics. And 4 different docs plus some ER visits.

You might like to contact your docs and ask about a nebulizer with saline and airway clearance to help move everything out of your lungs while awaiting final diagnosis.
