We've been in the orange zone for a bit here. My allergist said the air quality have been pretty bad. How does this make my allergies and PND worse b/c it feels like it does! Does it make me have a lower tolerance to my allergens?

Here in the Twin Cities area we've had a few low air quality days the last two summers. I get a feeling in my chest like I have heartburn, and it lasts most of the day for a few days. I have asthma, so maybe it' s really my lungs that are protesting, but it feels like heartburn to me.
At first I couldn't figure out why I was feeling like that, then I correlated it with the air quality. The last time the air quality was bad, I got the heartburn feeling before I even found out it was a bad air day.
I don't know what PND is?

when mucus from your nose drips into the back of your throat.
