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
- Learn the warning signs and when to call the doctor or 911.
- 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.
- Take breaks and ask for help. Caregivers need care too.
