DS#2 has got a round red spot on his cheek - very small and it seems to be raw as if he's taken the top of. Noticed it yesterday when he came home from nursery. I'm a bit nervous as he's picked up headlice and threadworm there in the last few months. It's not got any bigger and it doesn't seem to hurt him - could it be impetigo or something less horrible?
thanks for any advice
