Which doctor treats this
- Start with your primary care provider (family doctor or internist).
- They may send you to a dermatologist (skin doctor).
Back to school, work, or sports
- Stay home until you've had no fever for 24 hours without fever medicine and you're feeling better.
- For the next 5 days, wash hands often and wear a mask around others.
Pregnancy and breastfeeding
- If you're pregnant or planning to be, tell your prenatal provider about this condition.
- Some skin medicines, like isotretinoin and retinoid creams, aren't safe in pregnancy.
- 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.
- Ask before taking any pain reliever. The FDA advises avoiding ibuprofen and naproxen after 20 weeks unless your doctor says to.
