Which doctor treats this

  • Start with your child's pediatrician.
  • They may send you to a pediatric specialist: a pediatric ENT doctor.

Children, pregnancy, and older adults

  • Babies: Some neck lumps are cysts present from birth.

Pregnancy and breastfeeding

  • If you're pregnant or planning to be, tell your prenatal provider about this condition.
  • Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
  • Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
  • Breastfeeding: Most medicines are fine, but ask. The NIH LactMed database lists what's known about each one.

For caregivers

  • Keep a list of your child's medicines, doses, and doctors on your phone.
  • Tell teachers, coaches, and sitters what to watch for and what to do.
