How to get rid of pimples on arms and chest?

What are these little bumps on my chest/arms, and how do I get rid of them? (Picture included)?

• For about 5 years I've had these little bumps on my chest and arms. Only now is it really standing out on my chest. It's not as bad on my arms, but it's still there. I exfoliate and use lotion, and it's not going away. I do shave my chest, shoulders, and forearm (i'm hairy I know) if that makes a difference. But even on the parts of my arm I don't shave I still have those bumps but there not very noticeable. They're really embarrassing and I would like them to go away. Here is a picture of part of my chest, for the past week this is the worse it has ever been. http://tinypic.com/view.php?pic=345dctk&s=5 I'm 15 by the way, and the red blotch is me scratching it (it's been itchy for the past week too).

• Answer:

  It's most likely folliculitus. I have the same thing, and have never been able to get rid of it. If it bugs you badly, go to a dermatologist. Mine gets worse when I'm stressed.
