My doctor told me I had EIA, BUT the other Dr. told me I had Vocal Cord Disfunction (VCD) it has the same symptoms as asthma but one differenece - asthma you have trouble getting air OUT VCD you have trouble getting air IN. He said it is most common in young women who are physically active and women in their 40's who are active. I use an inhaler when I need it but it helps but by realizing what is happening and stopping and relaxing I can usually prevent it, I have it less often now only when I am going up a really steep hill and my breathing gets very heavy. Check it out on the internet, is is almost always diagnosed as asthma.

I fell early this year after a bike ride and had an "attack" I was riding up a hill so my breathing was hard and when I fell I guess it made me worse, I was alone and couldn't get air in, the first dr. immediately said EIA, did the breathing tests - NO problems but "sometimes that happens" - should have known something wasn't right then! Good luck, and find a good dr. both of the ones I saw were asthma/allergists in the same practice, I don't trust doctors much anymore - they want to label something b/c it seems to be what you might have after reading up on VCD that seems to be what I have, no real treatment for it tho.
