Yay, Amiga! I mean that you're here......hoping that the news gets better though.....Oh, no.
I don't want to give false hope, but we don't know what is going on with her. Can you get her into a lukewarm bath deep enough to float in?
It may traumatize her too much, go with your instincts on that. You are right. She may have serious internal injuries. Kevin's advice was good. Keep her in, quiet, warm, with plenty to drink, and give some electrolytes when you get them. If you pray, I would do that, too.
I am wondering if there is air in her body cavity. That can happen with sudden blunt trauma, such as being shaken.
