What is wrong with my pinky toe?

Even if it is broken, the doctor is going to do exactly what you did. The only thing they can find out, is if it really is broken. Try to baby it. Is it possible to be broke? sure. is there much you can do? no. If you really want to go to a doctor, go to a chiropractor. If it is dislocated, he can relocate it, and often for cheaper than the doctor.
