@farmerman,
In addition to the other things you're doing for it, you should also ice it, elevate it, and take ibuprophen, all of which are used to reduce swelling.
Swelling restricts blood flow, and you want to increase blood flow in order to help the injury heal.
Immobilizing the area and protecting it from further stress also helps reduce swelling.
Severe bone fractures, even in small bones, can lead to blood clots. So even if the hospital doesn't do anything other than confirm the fracture and tell you to keep the swelling down, it's still a good idea to have a Doctor check it out.
Good luck,
