So my baby has had a ringworm on his cheek for maybe 1month and for the past month in a half it's been what looks to be gone i don't see any ring. It looks like he still has some scarring though. And it when he gets hot or irrated his check starts to turn red and you see the ring again. Is this normal? I'm still applying the cream doc prescribed for it 2x a day. Any tips on how to get rid of it faster and when do I stop applying cream?
