DD (3) has come home from nursery with a rash under her armpit, on her chest and her leg (see photo), it's red dots and they don't fade with a glass tumbler. She's already had chicken pox, so it can't be that. I'm wondering if this looks like hand foot and mouth? Im going to obviously get her seen by a GP but I'm just anxious in the meantime for some reassurance because the rash doesn't fade when pressed etc.
