For many women, in addition to experiencing dysmenorrhea during their menstrual period, they often encounter various discomforts. Many young and middle-aged women experience breast pain before and after their period. Is this normal? Many women worry that this is a sign of a pathological change in their breasts. Generally speaking, this type of cyclical breast pain or stabbing pain that occurs as the menstrual cycle approaches and then eases or disappears after the onset of menstruation is mostly due to changes in hormones within the body, and it is a normal physiological condition that does not require treatment.

Will breast pain still occur if pregnant in the same month as premenstrual breast swelling and pain?

If women experience breast pain before menstruation, it is likely caused by premenstrual syndrome. Premenstrual syndrome in women is often caused by psychological stress and mental factors. It generally causes symptoms such as headaches, breast pain, limb edema, and abdominal bloating. At this time, it is advisable to give psychological suggestion under the guidance of a doctor. Generally, psychological comfort and guidance should be provided to help women relax. Additionally, a reasonable diet, increased nutrition, appropriate physical exercise, and quitting smoking are all good treatment methods for premenstrual syndrome, as it is caused by psychological and mental stress in women. Therefore, it is possible that a woman might still feel tense after becoming pregnant, which might result in chest pain. The specific situation depends on the individual conditions of the woman, as not all women necessarily experience chest pain. Therefore, it is necessary to analyze each case individually. If further questions arise, please consult a doctor at a hospital.

What should I do if I have breast engorgement and lumps during postpartum confinement?

Postpartum breast engorgement and pain with lumps may indicate milk stasis within the breast. It is recommended to let the child suckle more. If the engorgement and pain persist due to a significant amount of residual milk, you can manually express the milk or use an electric breast pump to remove it to prevent the accumulation of milk, which can lead to mastitis. If the pain is severe and accompanied by fever, it is advised to stop breastfeeding from that side and seek medical attention promptly. If necessary, oral anti-inflammatory medication may be administered. During the postpartum period, care should be taken to avoid putting pressure on the breasts.

Is breast pain 8 days before menstruation an early sign of pregnancy?

Breast pain and swelling eight days before menstruation is mostly not a sign of early pregnancy, but a normal physiological phenomenon. The period before menstruation is the luteal phase of the menstrual cycle. After ovulation, the ovary forms the corpus luteum, which secretes estrogen and progesterone to maintain the uterine lining. Estrogen stimulates the growth of ductal cells and alveolar cells in the mammary glands, and increases the permeability of local blood vessels, leading to breast enlargement and sometimes pain. This is generally a normal physiological phenomenon and usually returns to normal after menstruation. However, it is also necessary to rule out the possibility of mammary hyperplasia, breast nodules, or even breast tumors.

How to treat mastitis and breast pain

For breast pain caused by mastitis during milk engorgement, we can use hot compresses and massage to fully expel the milk. Locally, a 25% magnesium sulfate poultice can be applied for 20 minutes, three times a day. After breastfeeding, cold compresses can be used to reduce the pain caused by milk engorgement. In cases of mastitis, it is important to keep the nipple clean, frequently washing with soap and warm water. Before and after breastfeeding, the nipples can also be washed with 3% boric acid solution. For inverted nipples, gently squeeze out the nipple before cleaning. However, it is not advisable to wipe with ethanol, as ethanol can make the skin of the nipple and areola brittle, leading to fissures. Develop good breastfeeding habits, feed at regular intervals, ensure the milk is fully drawn each time, and if not, manually express or use a breast pump to remove the milk.

What is the cause of breast swelling and pain before menstruation?

Menstruation has not yet arrived, but the breasts are already in pain—this is a common annoyance for many women. Many women experience swelling, hardening, and even pain in their breasts before the onset of menstruation. In severe cases, even slight vibrations or bumps can cause unbearable breast pain. What causes this? It all starts with a mysterious substance—hormones. Each menstrual cycle, levels of estrogen and progesterone rise, causing the mammary ducts and lobular duct endothelial cells to enlarge, and the ductal epithelial cells and stromal cells to become congested and swollen, leading to pain. Thus, different degrees of pain occur before menstruation.
