Key takeaways:

  • Breast or nipple pain before your period affects as many as 70% of women.
  • Premenstrual breast pain is most likely caused by the levels of estrogen and progesterone changing during the second part of the menstrual cycle, but the exact cause is unknown
  • Painkillers, a well-fitting bra, and exercise are some of the remedies that can help reduce breast pain before your period

If you’ve ever wondered why your breasts hurt before your period, the hormonal changes linked with premenstrual syndrome (PMS) might be the answer.

In this article, we’ll walk you through what causes breast pain before your period, common symptoms, what you can do about it, and when to see a doctor.
