How can i stop the pain in my shoulder till i go to the docters?

my mother and sister and i are travelling in new york, we went to the bronx zoo and at one of those telescope things i tripped over the base and fell, when i fell i broke my fall by landing on my hand with a bad angle then collapsed onto my elbow, now for some reason my shoulder is quite sore. i am using arnica and tiger balm but it dosent seem to be working, i think its a nerve or ligimint problem or possibly i mightve dislocated my shoulder or fractured it, anyway what would be some way to subside the pain until i go to the doctor back in australia? also i do take pain releivers but mum wont allow me too often and my shoulder still hurts.
