About a week ago I started noticing small red bumps on both sides of my torso. They did not itch very much but they hurt like a bruise. Yes I have recently moved and yes I've washed all my bedding. I have not changed detergents or soap. I'm now noticing the bumps on other parts of my body. There were two on my butt, one on the back of my arm and then the one that caused me to start being concerned is the one between my vagina and anus. It again hurts but doesn't itch. What could this possibly be? How can I get rid of them?

Go to a doc.
He will now what they are.

Yes, you need to see a doctor for this. He will rule out chicken pox, shingles and the like.
