My son has tiny red bumps and some skin colored bumps all over his chest, stomach, back and neck. The skin colored ones are on his face. I have tried allergy medicines, but they have not gone away. They just keep spreading. It doesn't seem to bother him and doesn't itch, but it concerns me. I have washed his sheets and clothes over and over again in sensitive skin detergent. He has had this for a total of a week, so I thought it might be viral, but no one else in our family has this. He is six years old. Do you have any help?
