Could this be a scarlet fever rash? DS has had an awful throat with a rash, had amoxicillin last week and everything cleared up. Three days after amoxicillin finished this rash is back and anbsolutely everywhere ! His throat is ok though. The nurse practitioner I saw said it couldn’t be scarlet fever because his throat is now ok. Said he’s probably just coming down with something. It’s spreading as I watch it and quite worrying. It is blanching though, thank goodness! Thanks x
