My son has has this rash for going on 3-4 weeks now. He has no other symptoms other than a runny nose off and on, no fever what so ever. It does itch, but it’s manageable I think. He is almost 19 months old. It is mostly on his thighs and belly, but has also migrated slowly down his leg and on his left arm. I have taken him to the doctor twice. First they gave him a steroid cream and we used it for almost 2 weeks. Next they gave him a fungal cream we have been using since Tuesday with no relief.
