Generally, breast pain before menstruation in women is more likely caused by premenstrual syndrome rather than ovulation, as ovulation occurs approximately 14 days before the onset of menstruation, which is still some time before the period starts, so typically, women do not experience breast pain due to ovulation. It is advised that women experiencing breast pain before menstruation should visit a hospital for a systematic examination under the guidance of a doctor to rule out any organic changes in the breast tissues. If it is confirmed to be caused by premenstrual syndrome, it is important to provide psychological comfort and suggestions under the advice of a doctor, helping women smoothly get through the premenstrual period. If you have further questions, please consult a doctor at the hospital.
