How do you know if you broke your arm? I was running and hit my arm on the corner of a trailer and now it really sore and swollen
You probably just dislocated it. If you had broken it, you'd be screaming and crying, wishing that your arm wasn't bending the wrong way or that the bone wasn't protruding from your forearm.
does it hurt and you should really go to the doctor
Broken bones are usually associated with loss of movementNot just swelling and painMan up !
