Absolutely- thanks for the validation too! I have read several studies indicating that the steroid in these inhalers ( especially if used daily for a year or more) can definitely increase your chances of getting MAC disease! There is a higher risk if you already have lung disease such as Bronchiectasis, as I did. It just shows that you need to be your own health advocate. Do your homework, question your medical team, medications, and most of all listen to your own body! I took myself off the Trelegy and at 2 weeks-no wheezing. I have shortness of breath but mine is tolerable for the most part. (I have used the rescue inhaler twice during this 2 weeks since stopping Trelegy.).
