NAC is a capsule, not a saline spray - please see my reply above. The saline solution is inhaled through a nebulizer so it penetrates deep into the lungs where the infection hides.

I'm not familiar with pulmonologists near you, the best way I know to find one is to start calling pulmonology practices and asking if they routinely treat MAC patients. If you have a hospital that specializes in respiratory care, they might have suggestions for you, too

Can you tell us a little about when and how you were diagnosed? Has anyone suggested you begin airway clearance, one of the pillars of MAC management?

This link will list all the Drs in your area that have experience with MAC and will also rate them. I see top of your list is Dr Whitehouse an infectious disease Dr. and he is taking new patients https://www.medifind.com/conditions/nontuberculous-mycobacterial-lung-disease/6433/doctors
The saline nebulizing is important. Drs often prescribe 3 or 7% hypertonic saline that comes in little plastic tubes. Then you have to buy a nebulizing system to inhale the saline. Hopefully once you see a good Dr they will recommend it. Some people do not wait for that and just start the saline nebulizing by getting the hypertonic saline on Amazon.
