[5h]

I spent 36hrs in hospital after an asthma attack last year (3 days in a super dusty environment), it was noticed then but not to the full extent - I think after normalising the asthma symptoms with a bunch of salbutomol nebulizers (iirc) I was ~55. I'll ask when I next go to the doctors :)

Before I was diagnosed with asthma, I just knew that at some places (my mother in law's was common), I'd have poor breathing after a while. Just learned to relax through it, and the symptoms would lessen after I left.

I go to get diagnosed, and they give you a nebulizer with something that triggers symptoms if you have it. I didn't visibly react, so the tech did it again, then measured the difference in my breathing. Whoops, the lack of visible response meant that I should have stopped after one dose.

So, I couldn't leave until after enough doses of an inhaler that it went back to normal. About 7 hits, I looked like I was sunburned for a while.

Like Elric said, it could be perfectly normal. Sometimes this tech is as much a nocebo as it is a help.
