Sounds like you'd benefit from taking a first aid course. You can see if the Red Cross offer one near you, or your local mountain rescue or lifeguard station if you live near one of those. As well as RICE you can learn some more useful skills: treat injuries and burns, administer CPR, etc. That said, for suspected broken bones an X-ray really is recommended. Depending on the nature of the fracture, you might need a cast instead of a sling and even the most experienced doctor can't tell you which until they've seen the X-ray results.
