Which doctor treats this

  • Start with your primary care provider (family doctor or internist).
  • They may send you to a hematologist (blood doctor) if it doesn't go away.

Children, pregnancy, and older adults

  • Children: Swollen neck nodes are common.

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.

Outlook

Most go away.
