Dear austin_07:  Skin on the breast is like skin anywhere on the body and is subject to a variety of abnormalities, including pimples, bruises, etc. etc.  Without evaluation, it is impossible to speculate on what this might be.  I suspect it hurts because you popped it.  However, if this gets worse or does not get better, you should have it checked out by your doctor.
