Which doctor treats this

• Recovery time varies. Ask your care team when you can drive, lift, work, and exercise.

Children, pregnancy, and older adults

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

• Go to visits when you can and take notes.
• Keep a list of medicines, allergies, and doctors in one place.
