@bbeers I don’t know where I’d be without my team of ID doctor, pulmonologist, and lung surgeon. Way back when I was diagnosed with MAC ( 2016) my pulmonologist told me to go to infectious disease. Sue said it well. We really need both to manage MAC - a team. Mine always communicate with each other about me. Someone from the team has contacted me every few days lately because I am struggling with RSV . Having a team is best because “two heads are better than one”. They can discuss your unique situation and share ideas. If you aren’t able to have that team approach your ID doctor would be most knowledgeable about MAC and treatment. You need that! Irene5
