bitten

Hi, I got bitten 2 days ago, don't know what it was that got me.... my eye is swollen up, red mark (which I've read indicates infection) is spreading across my cheek, I'm itching on my face, my eye is swelling shut... any ideas of what to do for it? It happened 2 days ago, I vaguely remember swatting something away in that area. Each day when I've awoken its been more swollen than the day before. i don't think its a spider bite, someone checked for me an there are no teeth marks.

I've been using Dr. Chrisopher's plaintain sting salve, if its helping I can't tell. Any other ideas?

Thanks,
Lisa
