I have a fair amount of infections and flare-ups. Sometimes this leads to some scary exacerbation situations. Anyway, I tend to feel (most of the time) that I've been beaten about the chest and back. I use 3 inhalers daily, nebulizer daily (sometimes just when needed) and an AeroBika. I'm trying to keep mucus moving and coming up .. the best I can. It isn't very often that my lungs feel good, calm and relaxed. How do your lungs feel?
