Which doctor treats this
- Start with your primary care provider (family doctor or internist).
- They may send you to a gynecologist (OB-GYN) or a breast specialist.
Back to school, work, or sports
- Most people keep up normal school and work. Rest when you need to.
Children, pregnancy, and older adults
- After menopause: Changes usually ease.
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.
