I know the feeling. I've had asthma for over 20 yrs. and now mild emphysema and something else they've yet to identify. I'll see my pulmonologist in Oct.
Though, I must tell you since I quit smoking several years ago, the tests that they've done on my lungs so far PFT's (Pulmonary Function Tests) show that my lungs are doing pretty good! So I will wish for you the same!!
Good luck and keep me posted!
