my 7 year old staryed a few days ago with tiny red bumps on face that kinda look like pimples, thought maybe a heat rash then as days go by i started seeing more now its on his face , few on his neck and chest , my 4 ear old woke up yesterday with red pimple like bumps next to his ear like in one spot and a few spots outside of that, now its by both ears and its a few o face and on upper arms and looks like it trying to get on his back , could you possibly tell me what it could be? i thought it could be chicken pox but there not itchy or running a temp and act just fine
