my sister was jumping in the shower and cought her toenail on the drain. The toenail became seperated somewhat. we soaked it in water beacause it was bleeding quite a bit. She hasn't been walking around much. (this happened on wednesday night) and she hasn't gone to school thursday or friday. my mom was looking at her toe just a few minutes ago and it looks like there is blood and clear fluid underneath her nail along with a buble. When should we start to be concerned that it has become infected. It can't hurt too much because she wanted to have a friend over and to go swimming.

Thanks
