My Office Allergy Is So Bad, I'm Ready to Quit

I have a dust mite allergy, but I don’t have any symptoms at home or anywhere else—only when I step into the office. The floor is carpeted and never vacuumed, and as soon as I get there, my symptoms flare up badly.

It gets so bad that I start sneezing and making weird stomach noises that sound like I’m passing gas. To my coworkers, it probably sounds like I’m sneezing and farting on and off all day.

It’s really embarrassing, especially since our office is super quiet.

I’ve tried antihistamines, but they haven’t done much. Is anyone else dealing with something like this?
