Living with it

Support groups and helplines

• Genetic and Rare Diseases Information Center (GARD): Free NIH information on rare diseases, including where to find experts and patient groups.
• National Organization for Rare Disorders (NORD): Patient groups, help finding care, and aid programs for rare diseases.

Children, pregnancy, and older adults

• Women 20 to 40: Most common.
• Women: More 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.
