Since having kids, I have had several eye infections. One with symptoms like you describe. Stuff the kids pick up at daycare and bring home.
My advice if you can't get to a doc? Call your friends with kids. They'll have a tube of the pink eye medicine in a drawer from last time they had it. Probably it will clear up in 12 hours once treated.
Note, I am not a doctor. That's just what I would do if I were in your situation. I hate that infected eye feeling.
I'm sure others will chime in about the dangers of using somebody's prescription without a doc. Flame suit on.
Good luck.
