Thanks very much for explaining that!
I quit smoking 10 years ago; I was heavy from about 19-39.
I found I couldn't breathe so well after Covid and the first doc I saw gave me Serotide 50/500.
He thought is was asthma but said I'd need a special test to find out for sure. Then, a few months later, when the spirometer test had no increase after the ventolin, he said emphasema. I run 20 km a week so found this odd and went to another hospital. I see the specialist next month.
I had asthma, seemingly, when I was a baby but never again, leading a sporty life.
Thanks again.
