My daughter is having rashes like this all over her body. It itches sometimes but not always so I'm ruling out that it's eczema. She's currently having a bit of cough and runny nose. Anyone knows what it is?

sometime its due to body tempreture. to heaty inside can cause this too. my son will have this type of rashes when his body tempreture is high. when kkh before but nothing he is allergy to or any skin problem. i just sponge him with slighly cold water and its gone. better to consult doc first and ask.
