Welcome to Mayo Connect. I’m sorry you need to be here, but am glad you are near Mayo.
My story is somewhat similar that I had sinus infections a few times a year that would clear with antibiotics. During Covid and in a new city that was hard hit by pandemic, it was hard to get in/get treatment. I had a lot of post nasal drip and persistent coughs. CT after pandemic showed a lot of nodules and a f/u CT a few months later showed bronchiectasis and changes suggestive of MAC. My pulmonologist went on medical leave and I lucked into a cancelled appointment at Mayo. They started meds to decrease PND, taught me airway clearance, did a bronch and ruled out MAC. Very thankful to them. I was able to get into Penn’s clinic and am stable now.
Others here have reflux and will probably have suggestions. Best of luck to you.
