Why do my breasts hurt before my period?
Breast pain before a period is usually cyclical breast pain, a hormone effect on breast tissue. It feels tender and heavy, on both sides, and is worst in the week before bleeding. It affects most women at some point, and it fades as the period arrives.
A well-fitted supportive bra, cutting late-cycle caffeine, and simple pain relief cover most of it.
Different rules for different pain: a new lump, one-sided persistent pain, skin changes, nipple discharge or any breast change after menopause is not cyclical territory and needs examination promptly. Lumpiness that comes and goes with the cycle is common; a lump that persists through a full cycle is the one to show a doctor.

See a doctor promptly if
- A new lump anywhere in the breast or armpit, whether or not it hurts
- Skin dimpling, puckering, thickening, or a nipple that has newly turned inward
- Blood-stained or spontaneous discharge from one nipple, or persistent rash or crusting of the nipple
- A red, hot, swollen breast that does not settle, especially if you are not breastfeeding
