What does it mean if you have sore nipples and you are not pregnant or going through pms?

Answer 1

If you are using a contraceptive, then that may be the source of the problem. And changing contraceptives may be the solution, particularly getting a different progestin (progesterone-like substance), because progesterone more often causes breast swelling and tenderness. If you are not on contraceptive you should verify that you are not pregnant.
