Hei, may I answer your health queries right now ? Please type your query here...Can you tell me what the small, pimple like rash is on my children s neck? they sometimes come up red, but then reduce, and sometimes look like they have pus in them. They seem to be contagious and be spreading. They don t itch. The dr said a name that starts with v, and they would go away by themselves, but it s taking ages and I d like to treat them.
