Contusion: Any part of the body, when smacked, will swell and be painful and sometimes might bruise. It sounds like you hit your chest on top of your nipple which is causing this. Ice can help it for several days and then just wait for it to spontaneously improve which it likely will if what you describe is all that happened.
