She should ice her wrists for now but she should also be examined by a sports injury doctor. At least that way you can be sure of why it hurts and what exactly she can do, or not do, to help. Good luck.
I have wrist pain too, but I've been working on strengthining which helps a lot, I can tell when I slack off on the excercises and it starts to hurt again. Here is a very helpful video which is exactly the wrist excercises I do, and it helps sooo much.
Me too! My wrist are smaller than 5 inches around and I have very bad wrist pain. My left wrist clicks all the time. I ice my wrists ever day after gymnastics, and sometime I have to take meds. I do a lot of wrist workout before vault and floor. I roll my wrists in a 'meatball' kind of way. Back handspings really kill the wrist and so do handstands. Sometimes just taking a break and rolling her wrist might help.
