Aspergillus after Bronchiectasis/MAC

History of brocniectasis/MAC diagnosis at NJH in December 2018. Had right lower portion of right lung removed June 2018 due to unidentified mass (mycobacteria). NJH stay of 10 days, went home with treatment plan of 2xdaily airway clearance. Slowly regained health and been doing fairly well until recently. November 2023 got sputum result of Aspergillus flavus. Johns Hopkins doctor ignored despite my repeated attempts for info. Finally responded, 2 mo. later that never treat till 2nd positive sputum….but did not order 2nd sputum. Sputum ordered by primary physician and result was Aspergillus Fumigatus. Found another pulmonary doc with MAC experience. He ordered 3rd sputum which recently came back Aspergillus Niger. No contact from physician and no treatment offered or discussed at all with me. I do have appointment next month. I am having symptoms similiar to when MAC first began. I am nearing 70 so not sure I even want treatment but would like information. What should I expect from physicians? On,y one who seems concerned is my primary care physician.
