I don't know anything about how this problem relates to aircrew medicals. What I do know is that I had the same problem for some years before I started to regularly (twice a day) use a steroid inhaler (Flixotide) and for emergencies I have Bricanyl. I used to cough and wheeze every day - especially about an hour after getting up. I found it hard to do exercise and when I got a cold or flu I would be laid up for weeks with bronchitis. My life has been transformed. I am not happy using steroids permanently but the alternative is so bad that I put up with it. I am so much fitter now - I can exercise at a much higher level. I think that because I do not cough all the time that my lungs are in much better working order and I am not nearly so prone to going down with every cold and cough going. I am 46 and I was diagnosed 3 years ago with late-onset asthma which I think originated when I had pneumonia about 14 years ago. I do believe that managing the condition and keeping it under control is right thing to do.
