is heat rash raised
Prickly heat rash, also called miliaria, is a rash that can develop after a person sweats far more than usual and sweat glands become blocked. Babies and children can also get prickly heat rash during hot or humid weather because their sweat glands are not fully developed. Prickly heat causes an itchy rash of small red raised red spots with a prickling or stinging sensation. Prickly heat usually affects parts of the body covered by clothes, such as the back, abdomen, neck, upper chest, groin or armpits. Prickly heat usually clears up on its own within a few days.
