My daughter 4 1/2 years old has a rash that appeared out of the blue looks like bites. Not itchy. But a single itchy one in back. What could it be?

A few possibilities. It could be bites, but could be viral, or a reaction to something she was exposed to. Best to have it looked at by her doctor or consult with one of us on HealthTap Prime. We can help you better if we can see the rash.
