Red bumps?

Nikki
Ok, so I'm just a little curious. I've had these red spots on my hand (and one on my arm) for as long as I can remember. They one next to my pinky is an actual bump, but very tiny. They have never been painful or itchy, they're just there. I've had more people asking me about them recently, and I have no clue what they are! Do any of you guys have anything like this, or possibly know what it is?
