Have I developed a dust allergy at 20?
The only symptoms I have are the sneezing and sometimes a runny nose. I did some research and apparently an allergy tends to develop around puberty, but I'm 20 and finished that a long time ago and this is recent.
I'm also not sure if it's actually dust/mites or if it's a reaction to dry air, but I'm not sure how to tell.
If I am allergic, how do I deal with it? Or how do I tell if it's just the dry air?
