An interesting question.
But I had never really heard of prednisone being used to "reverse" asthma symptoms, but, to relieve them.
Prednisone is an anti-inflammatory.....and for the most part, many people with asthma often have several triggers.... I suppose it depends how sensative you are.
I have been on about 6 separate prednisone treatments,
and thought I had removed all triggers.... I was out of work for half a year.... it was so bad.
But it is always worth going to a pulmonologist when you develope any breathing problems, so that a mild problem doesn't become a terrible and major problem.
