Cherinyc I am quadupling the suggestion you go to the doctor.

I have had exercised induced asthma since I was a kid but it was controllable

2 summers ago it became constant. I finally went to the allergist last summer because "I WANTED TO RIDE MY BIKE UP HILLS ! ! ! "

Like you I would have trouble breathing (do you wheeze?) I couldn't get enough air in because I couldn't blow enough of the old air out. I could still slow pedal and recover at the top and keep on going.

For a long time I just used the albuterol 1/2 before going out and that took care of everything.

I'm now with makbike and Mary and take a lot more stuff: Advair, clariton, supposed to take Nasonex - hate it and don't see any change AND it's expensive so I don't take it. Went to the doc yesterday and he added Singulair. I think that w/the advair may be the miracle drug of choice, went 25.6 miles today at a pace of 15 mph and talked the whole time

Get to the Doc and have it checked you could have a lot more to lose if you don't
