@ktkarenst, Be sure to ask him about whether or not you have bronchiectasis, and if maybe you have GERD or acid reflux. These are two common culprits for attracting mac disease. Your CT scan is what can reveal bronchiectasis. Please take the time to read over older posts as there is a lot of info in our conversations. Check out the Discussion board too, there are pages and pages of helpful topics concerning this disease. It is located on the main Mac and Bronchiectasis home page. Let me know if you need help navigating this site, ok?
