My Daughter Was Bitten By A Scorpion At School Today.

My daughter was bitten by a scorpion at school today. It was looked at and treated by the school nurse. She's been doing great for hours and has very little pain. I've been reading about scorpion stings and it's making me think I need to take her in. She has no symptoms that anything is wrong. Should I take her anyway? It's been about 8hrs
