Itching and rash from dust?

Recently I decided to do a through clean, and hoovered underneath my furniture- but as soon as I did I noticed that my arms and hands were itching and i had red blotches where it itched. I assumed it was so kind of mite or allergy and washed my forearms. Only now the dust must have gotten into he air because in the room my eyes are always burning, I itch all over and it gets worse when I touch things, especially fabrics. It’s even gotten into my hair! How can I get rid of this dust and get my room back? Also, what’s causing it? I’ve never had a reaction to dust etc before…

my left eyelid is swollen, but my eye is not red at all?

I think it could be pink eye, but I will not know until I go to the health center on tuesday. It is closed on monday for labor day. It is not swollen a lot no discharge a little bit of itchy and burning feeling, but no other symptoms. could it be anything else, and any suggestions on treatment until then. I have been using pinkeye drops and allergy drops to treat as best I can however I have no idea if it is doing anything. advil has also been reducing the swelling.

May I mention I occasional have itchy burning eyes but not all the time.
