Just been told 2 yo DS has this. They affect his neck, up to his jawline. The practice nurse said they're not contagious, will take weeks/months/years to go and that there is no treatment. She printed up an info booklet for me to read and now I'm confused as it says it IS contagious! DS may have picked it up from infected toys at nursery/playgroup, but most people have natural immunity to the virus and don't pick it up, which could explain why rest.of the family haven't got it.
Can anyone she'd more light on this for me please? Am feeling very confused (and worried!)
