Ok so my 3 year old daughter had some lose skin on her thumb at school yesterday and she said she picked it and it started to bleed and she put a band aid on, and this morning she came to me that her thumb hurt and it looked like this (picture below). Any advice? Does it look infected? She said it hurts and it feels warm to the touch.
