My son has little 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. Just keep spreading. It doesn't seem to bother him and it doesn't itch but it concerns me. I have washed his sheets and clothes over again in sensitive skin. He has had this for a total of a week and 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?
