Too still put my input in on this... I'm an EMT... your best bet is to wrap it however you hurt it in an ACE bandage till you can get to a doctor, and take it easy on it.
Two things to try as well:
Go to the student health services at your school, they might be able to do something.
Call your primary doctor at home, and have him send a referel to the hospital, then insurance will cover it.
