Two car accidents and now your wrist.

They say things happen in three's so I think you're all done now.

I hope you have ice on it.
You could go to the ER if you're worried about making it worse (I can't blame you!). They'll at least splint it or something until you can see the Doctor in the morning.
Get the X-rays that the ER takes so the Dr. can see them tomorrow.
I hope it's not broken! Feel better!
