Could this vague sickness be a mold allergy?

I’ve been feeling weirdly sick every day for a few weeks now. Strange head pain and pressure, runny nose, sometimes watery eyes… similar to the way I feel from my springtime allergies.

My hunch is that it’s a mold allergy because we have a serious mold problem in our old rental house. I had to wash away tons of black mold on our bathroom ceiling yesterday. When I’m in the bathroom, my symptoms intensify slightly. Ugh. Seems pretty obvious that the mold could have something to do with this…

My question is: are my symptoms possible with a mold allergy? Most of the stuff I’ve read online says that mold allergies affect the respiratory system, and I’m not having problems, there. Also, would a moldy bathroom cause me to feel sick for most of the day, when I’m far from the offending mold? Can the spores “travel” with me or something?

Can anyone clue me in?
