@godislove Hello there. I head up a group here on Connect called Mac and Bronchiectasis. You may want to request a sputem test from your pulmonologist to make sure nothing is colonizing in your lungs. Also, mention mac and bronchiectasis as a possibility to explain your SOB. Many of us in my group started out with the same symptoms as those you are texting with here. Most drs are not that aware of mac infections and tend not to look for it. Same with bronchiectasis that it detected with a CT scan. Never stop searching for answers.
