Living with it

• Keep a simple diary of symptoms, triggers, and medicines to bring to visits.
• Bring a list of your medicines and questions to each visit.
• Make your home safe from falls: good lighting, no loose rugs, grab bars.
• Ask your doctor whether it's safe to drive.
• Long-term illness can affect mood. Tell your doctor if you feel down or anxious.

Support groups and helplines

Back to school, work, or sports

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

Children, pregnancy, and older adults

• Adults over 50: Most 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.

For caregivers
