Hi Ashdaman,
I told the medical team that I grew out of my symptoms and I heard no more of it. I only get wheezy when there's a lot of dust around, I was never officially diagnosed as having Asthma despite similar symptoms I do suffer occasionally from rhinitis which is like asthma but not enough to warrant doing anything about it.
To answer your question there is nothing on my medical mentioning asthma, I do however have a small adenoma (growth) in my pituitary gland just below the brain and that will be on my medical cert for life to get checked regularly, what I'm trying to get at is that having something like using inhaler on your license isn't the worst thing that could happen and I wouldn't worry to much about it
