Dust allergies

I've been nursing a cough and a cold for more than 2 weeks now, it started off as a sore throat at first and later came out with the other symptoms.

My throat has gotten better after a week but my cough is still lingering. Every now and then I'd get a coughing fit that lasts for minutes and that scares the hubby - and frankly, it even scares me. I sound like somebody with TB or asthma.

We're thinking now that this might be an allergy. We keep cleaning and cleaning, but it still hasn't gone away, so hubby has taken apart our bed (and the bedframe) and is cleaning the nook & crannies of our bedroom. The thing with having wall to wall carpeting is that while it makes life more comfortable, it's also very attractive to dirt and dust. And how often do you clean under the bed, anyway ? We have this very cumbersome bedframe that is very difficult to move so the area under the bed very seldom gets vacuumed thoroughly. We do let our faithful Roomba go at it every so often, but unfortunately, Roomba - the tiny robot that it is - can only do so much. We've also thrown out dried flower arrangement we have hanging over our bed - while it was very nice, it was certainly a huge dust collector.

I'm also finding out that this dust mask that I picked up at the local dollar store is helping me breathe more comfortably. I've had this on for an hour now and I haven't coughed since. Hopefully, I get to shake off this cough when hubby is done with the fall-cleaning. I'm tired.
