@jr2366 Your story sounds a lot like mine. Except I had that lung surgery at NYU to cut out the nodule and do the biopsy. It was very painful, especially every time I coughed! That’s how MAC/MAI was diagnosed. I’ve never gone on any meds because my yearly CT scans show the nodules “wax and wane” and are relatively small, also, aside from the cough, I have no symptoms from MAC.
