Your son sound just like my youngest son. It almost seems like that he has a constant cough, croup etc. He was diagnosed with Astham about two months ago. He is on Flixtide and Ventolin. Also he has had redipred several times too many for my liking.

I am asthmatic and I have always been that way since I was diagnosed when I was 7. I am in my thirties now. I take Ventolin and Seretide everyday.

When I was younger I was told that asthma has a seven year cycle where it either gets better, worse or stays the same. I do not know whether I believe it or not.

Only other thing that I can think of is to try and find out what triggers it and try and avoid them.

Sorry I am not much help. Also sorry about all the typos as it has been along day for me as Aaron has got croup yet again. It never seems to end.
