I stubbed my toe worse than i ever have. i can't walk straight. i limp, walking on my heel. how do i know if it's broke w/o seeing doctor?

Xray: is the only way to tell if you broke your toe. If your pain is so bad you can not bear weight it may be best to see a physician for a proper exam. Alternatively, you have suffered a sprained ligament which will improve over time.

Really need Xray.: Sounds bad. Good possibility it's broken. But you won't know for sure without an X-ray and you need a doctor to order one of those.
