So since it was nice this week i started taking the kids outside to play, "im a nanny" and the same night i was outside i noticed a few red spots on my neck and shoulder a couple behind my ear, this is the only place they are, i looked up pictures of hives and they look like they are hives, at first i thought insect bites but not sure,sooo with that said does anyone know what helps them stop itching? and how long do they last
