You may actually want to have yourself checked for asthma by your GP. You can develop it any any age and that sounds, at least to me, like symptoms of it. Easily treatable in this day and age.
I've had asthma since I was 6 months old (38 years ago, mind you) with varying degrees. Probably about 15 years ago I had a bad case of bronchitis. Ever since, every small cold I get turns into full bronchitis without fail...probably because of the asthma. Nearly 10 years ago I also got laryngitis with the bronchitis. Now that's thrown in for good measure with each cold too. I *am* falling apart in my old age!
Would be worth checking out though, just to rule it out. Cold air is easily one of the most dominant triggers for my asthma.
Best of luck!
