I am 66 and have had two different/unrelated ling diseases. The first from exposure to isocyanates in automotive paint, the second is a rare one, less than a 1,000 cases in U.S
I doctor at National Jewish in Denver or I did..I am in complete remission now.
I have taken Advair, Flow Vent, Combivent, Atrivent, and a few more I can't recall the names of. Now only take Albuterol and that rarely, maybe a couple times a month. Flonase for messed up sinuses and lots of nasal washes.
I agree with taking inhalers with a tube extender. Otherwise it goes into the skin in your mouth instead of going down your bronchial tubes.
The worst was the massive amounts of.steroids. they will totally mess you up.
