Secondly, if you hurt yourself, GET IT CHECKED! Don’t assume that it will "go away." Don't be a hero. That does not mean that you have to go repeated times to the doctor if you don't need it.

That way, you make sure that it’s not serious and won’t get worse; and, if it does get worse, you can show your employer and its insurance company that you were indeed injured when you say you were and sought treatment
