My son has 2 small balls (kind of little bones) in his neck ...

Good afternoon Doctor ... When my son was about 3 months old I noticed 2 very hard and soft balls on the right side of his neck (almost near the nape of the neck) so I took him to the pediatrician and he said he was normal in children . But today, when I was 2 years old, I noticed that the roots are still there, and sometimes when he moves his head to the side, it is very visible. And I'm getting very worried about that. Do you think it's normal?
Expert answer:

What you say "carocinhos" are actually lymph nodes, small organs of defense scattered throughout the body they increase in size when they need to "work" for the defense of the region near where they are located. So usually increase in cases of infection and inflammation and in rarer cancer cases (this is probably your concern). Since your child has had them for a long time and they have not grown in size, so stay calm.
