Broken?

Yesterday my 17th year old daughter closed the car door on her arm and then fell on it!!! Yes she is a genius. She had to go to the hospital to see if her arm was broken or not. It didn´t show on the photos taken of her arm, but they said that if she has broken the Scaphoid it wont show until a week from now. So now all we can do is wait and hope that she has not broken any bones in her arm!
