hii mam my daughter age is 2years ihave breast tenderness and breast pain from last four days

A. Hormones are making your breasts sore. Breasts become sore three to five days prior to the beginning of a menstrual period and stop hurting after it starts. This is due to a rise in estrogen and progesterone right before your period. These hormones cause your breasts to swell and can lead to tenderness.
