widespread heat rash?

My 7 year old has a rash all over her back. They are a little itchy, mostly when touched by something.  They also end up hurting her if I try to put anything on it. There are also a few small dots showing up on her chest and stomach, shoulder and arm.  And there is a bad patch next to her mouth on one side and then a few on her forehead and around her face. I first noticed it a little on her back on Sunday, but the worst showed up Monday morning, picture was taken Tuesday night and they are still there but less angry looking Wed. morning.  It was warm this weekend, she had sunscreen on her back Saturday and Sunday. I'm really not sure what it is.

Hi,

This sounds like a heat rash or milaria , though nothing can be said with surety without having a look at the lesions.

'Miliaria (miliaria rubra, sweat rash or prickly heat) is a skin disease marked by small and itchy rashes. Miliaria is a common ailment in hot and humid conditions, such as in the tropics and during the summer season. '

'The prevention and treatment of miliaria primarily consists of controlling heat and humidity so that sweating is not stimulated. Measures may involve treating a febrile illness; removing occlusive clothing; limiting activity; providing air conditioning; or, as a last resort, having the patient move to a cooler climate.'

You could read more about the condition at the following links -
