Premenstrual breast pain is a common symptom among women and is considered a normal physiological response. It mainly occurs due to the increase in estrogen levels in the body seven to ten days before menstruation, leading to breast hyperplasia and enlargement, causing discomfort that makes the breasts sensitive to touch. There is no need for excessive concern as breast pain caused by hyperplasia is normal. Generally, the condition improves after menstruation and does not require special treatment. If the pain is severe, applying heat can help alleviate it.

Is breast pain before menstruation the ovulation period?

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.

Can breast swelling and pain before menstruation be relieved by massage?

It is advisable to go to the hospital for a systematic, standardized, and reasonable examination before menstruation if you experience breast swelling and pain, in order to rule out diseases that could cause such symptoms, such as mastitis in women, mammary hyperplasia, or breast cancer, etc. If these organic changes in the female breast are ruled out and the pain is considered to be caused by premenstrual syndrome, you may gently massage under the doctor's advice and guidance to alleviate the pain. Be gentle and slow in your approach, and pay attention to the technique; do not pinch or squeeze with excessive movements. Please follow the doctor's advice for specific actions. If you have further questions, please consult a doctor at the hospital.

Can pregnancy cause breast pain?

Pregnant women are very likely to experience breast pain, which is one of the earliest signs of pregnancy. Symptoms like breast tenderness, sensitivity, and a stinging sensation usually appear within 3-4 weeks of pregnancy, sometimes even before a pregnancy test can be taken. This is primarily because, to better support the growth of the fetus, the body produces more estrogen, stimulating the growth of mammary glands and causing breast pain. Of course, as the pregnancy progresses and hormone levels gradually stabilize, breast pain will be alleviated. Pregnant women should not be overly concerned. However, it is also important to remind pregnant women that while this breast pain might increase discomfort during pregnancy, it is usually bearable. If the breast pain becomes unbearable, it is still essential to visit a hospital for a check-up.

Breast swelling, pain, and lumps, what is going on?

There are several types of conditions where lumps can be found in the breast. Breast tissue itself is essentially a hard substance that can normally be grasped or pinched by hand. Therefore, sometimes the lumps you feel in the breast are just normal areas of breast tissue protrusion, which generally disappear after menstruation or after subsiding. You do not need to worry too much about breast lumps that appear during this special period. Another more common type of breast lump is fibroadenoma of the breast, which typically occurs in women of childbearing age between 20 and 39 years old. Another condition is cystic hyperplasia of the breast. This is more common in middle-aged women, often with several hard nodules of varying sizes on both breasts, with unclear borders, which can cause pain, especially more noticeable before menstruation. When it might be a breast disease, it is advisable for patients to visit a hospital and consult a doctor on how to proceed.

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.
