@joyeous you sound like me...they say exercise would help with lung function. My lungs are functioning at 42%. How can you exercise when you can't get your breath. I, like you, struggle and pant going from 1 room to another. No more cooking or cleaning house. Feel great while I'm sitting. That's why I sit a lot. I was always active but those days are gone. My pulmonologist has tried so many things. Pick lines, antibiotics, rehab and nothing has helped.
