I Woke Up Thursday With My Wrist Hurting...(and Right Above

I woke up Thursday with my wrist hurting...(and right above it) I'm a cheerleader on 3 teams... I had practice that night and it was really sore. And it made it a little worse. It still hurts now. I know I didn't do anything tragic or major before Thursday or on. I had been tumbling but I don't know if that caused it because my wrists are strong and have never hurt before. Anyway I have practice tomorrow for all three teams. I don't know what I could've done. Advice or ideas of what it could've been?!
