Which doctor treats this
- Start with your primary care provider (family doctor or internist).
- They may send you to a dentist or an ENT doctor (ear, nose, and throat doctor).
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Some infections can pass to the baby during pregnancy or birth. Tell your provider if you've been exposed.
- Don't start or stop any medicine on your own. Some are safe in pregnancy and some need to be changed.
