What is the cause of breast pain a few days before menstruation?

Female friends generally experience some abnormalities in the body a few days before menstruation, because the body's immunity and digestive ability will decrease a few days before menstruation. At this time, you need to pay attention to self-care, not only pay attention to diet but also need to keep a regular schedule. Many female friends will experience breast pain a few days before their period. Below we will explain what causes breast pain a few days before their period.

Before menstruation, I feel breast pain and sometimes I can feel a painful lump. This is because the breast glands, like the endometrium, also undergo changes in the menstrual cycle, with a premenstrual proliferation phase and a postmenstrual recovery phase. The premenstrual proliferative period refers to the 7 to 10 days before menstruation. At this time, due to the increase in estrogen and progesterone concentrations, hyperfunction of antidiuretic hormone, and increased aldosterone secretion, the mammary ducts expand, the epithelial cells proliferate and hypertrophy, and the edema of the matrix around the mammary ducts causes compression symptoms and pain.

At the same time, the immature fibers of the breast increase, lymphocytes infiltrate, and the breasts enlarge, and you will feel distension, pain and discomfort. The menstrual recovery period refers to the period after the onset of menstruation, when the secretion of estrogen, progesterone and antidiuretic hormone in the body decreases, the milk ducts become smaller, the epithelial cells atrophy, the immature breast fibers decrease, and the symptoms of breast tenderness disappear.

It can be said that if you feel breast pain, it reminds you that menstruation is about to come. Some people compare the period before menstruation to "high tide", during which the breasts will swell and ache; and the period after menstruation to "low tide", during which the breast swelling and pain will be reduced or disappear. This is very appropriate. Therefore, breast pain before menstruation is a normal physiological phenomenon. There is no need to worry, be overly concerned, or carry a heavy mental burden.
