My son has a red like rash on his face and other parts of his body have like little pimple looking things and at first he has something on his hands that looked like ant bite marks but there is way to many and it is swollen a little and he says itches. Please help I have took him to urgent care twice first time they said he had a skin infection medicine hasn't helped except maybe with his face a little but it still kept spreading and then took him to a pediatric urgent care and they said he had scabies. Tried to upload pictures but it won't upload
