When I had the first attack last year my regular Dr sent me to do a regular stress and then the pulmary DR did all sorts of breathing tests, lung capacity,etc. EVerything was normal.

bmccasland. I hear on the no rhyme or reason. I rode the other day when it was really humid here and I was fine. Then when the attack happened the other day it was hot out but nice and dry. The only thing I can think of is that I was takeing it easier on the humid days and since it was dry out the other day I was pushing myself a little harder.

Tried to call the Dr today but his office didn't open until 1PM. Must be nice!!!
