Depends on where they are.....Don't know how old you are either, but from experience I know when I am sitting in class (in college) I tend to prop my head up with my hand. The oil off of hands can cause your face to break out.

Hehe i'm 14. Thanks for acutally replying. Hmm, I only rest my hand on my chin but never where the pimples are (they're on my cheek)

This is going to sound funny but do you talk on the phone alot and prop the phone against your face? The different oils and dirt on your phone along with rubbing could cause that. If so try washinf the phone and not touching you face with it when you talk.

May just be a coincidence. Do you only sleep on that side? Lol I donno...

Snap - me too. I have just been reading about triggers for facial flushing/rosacea at dr goeffrey nase's website Drnase.Com and he says that even warmth such as lying on a pillow or resting your face on the arm of a couch can raise the skin heat enough to cause rosacea which I think must explain why my pimples arfe only on the right side. Cannot offer a solution but suggest you see a doctor to get some antibiotics and advice.
