Well, Bug fell asleep last night still icing her ankle. That was 2.5 hours after I first learned of the pain. My husband ended up carrying her up to bed as she still couldn't/wouldn't put any weight on it.
When she got up this morning she was still in pain, but not as much. We had her put her old ankle brace on (because of your feedback), and sent her to school limping while crossing our fingers she would be okay. She iced it a couple of times at school, skipped PE, and she said "all of a sudden it felt better" sometime in the afternoon. I pressed her on if it was that she noticed it felt better, or if it suddenly felt better. She insisted that it suddenly felt better and got mad at me for asking. (you know, the "leave me alone I've already told you Mom" kind of mad)
Since then she hasn't complained once, and is happy as a clam. I'm still waiting to hear back from the PT, but I'm SO happy she's better!!!
