Hi, I've had asthma my whole life (19), but in recent years it's rarely a problem. What I have found out is that whenever I visit other people's homes it will get pretty bad very quickly, and can catch me off guard which is annoying. I first get an incredibly itchy nose and find it almost impossible not to sneeze constantly as well as itchy eyes and then the tight chest as it were.
In some cases I can put it down to pets or smoke or anything, but in some places I go to the house is spotless, not cleaned prior to my visit (no dust in the air) and they have no pets or anything.
What I would like to know is what could possibly be causing these flare ups, it's gotten to the point where I spend 2/3 hours at my Aunts or Grandmas and I end up feeling ill for the next 3/4 days because of it. Any ideas are fully welcome and of course if anyone else has had similar experiences I would love to hear from you.
Thanks.
