Do you have any other symptoms when this happens?

I would get this feeling of breathlessness not just in my lungs, but in my leg muscles too (hard to describe). And my heart rate would be up at 197 bpm. And this was happening at a level of exertion that I didn't think was THAT intense. What I finally found out was that I was very iron deficient and very anemic. .

This is very interesting.

When I get short of breath because of asthma my legs start to give out very quickly also

How anemic were you? I don't think I am anemic - I give blood on a regular basis and have never been refused because of low iron - but maybe this not a good measure (also the doc checked it and I was very good)

interesting interesting interesting hmmmmm
