Small bumps all over my body?

I know you are going to say call a doctor but it is a Friday evening, so no.

It started a few days ago with less than ten tiny itchy bumps on my right arm the same color as my skin. Everyday (especially if I scratch), more appear. I am getting them on my forearms, legs, but only past the knee, starting two days ago on the sides of my feet, and on the backs of my hands, but the ones on the backs of my hands are larger and look like small blisters. Oh, and I have one on my chest and a few on the back of my neck. Basically, anywhere my body may be "exposed" when wearing clothes. Don't know if that has to do with it, but that's what I noticed.

Any ideas on what these could be will be greatly appreciated until I have to wait until Monday to call my doctor. Oh and I also had a Staph. infection about a month ago if that makes any difference (still a few bumps there, though I got antibiotics). The infection was/is between my thighs in case that has anything to do with it too.
