For the past few days both of my eyes have been really itchy and irritated. The irritation has stopped for the most part but last night my left eyelid started to swell. I woke up this morning and it's gotten worse. I've never had any allergies that would cause my eyes to react this way, and it's never happened before. The closes incident I can think of is when I was working in an animal shelter and working with the cats made my eyes all red and itchy, but it went away after I flushed them out (and there are no cats in my apartment). I have n inkling that it might have something to do with the roaches in my apt. but I'm not sure. Any idea?
