Women's bodies are still understudied and not much is yet known. Despite medicine being so developed, not much is known about what happens to women's bodies throughout the cycle. The menstrual cycle is an important part of a woman or a menstruator's life. Not only because it determines their moods, and fertility, but also because of the way their body reacts and prepares for menstruation. If you have every notice your body to hurt, sore or just your breasts to go tender, your body may as well be preparing for your next period. Why Do Breasts Hurt Before Period?According to the American Academy of Family Physicians (AAFP), hormone changes due to menstruation are the most common cause of breast pain. In fact, the breast pain can worsen during the luteal phase when estrogen levels increase and the progesterone levels are low. These changes can also cause your lymph nodes to swell and it could lead to breast pain.Furthermore, an increase in prolactin can also lead to tenderness and swelling. This is the hormone that stimulates breast milk production in women following childbirth. It is present in the body and can affect the breasts even if the woman has not given birth or is not pregnant.Another time when breast pain can occur is during ovulation, this is when an ovary releases an egg for potential fertilization. This process takes about 12 to 14 days before a person has their period. But Did Your Ever Experience A Shooting Pain Only In One Breast?If hormones were only to be blamed, then the pain would happen in both breasts. However, many times women have reported that they feel the shooting pain in just one breast around menstruation. The explanation for this is that the cells in each breast respond differently to fluctuating hormone levels. Some are more sensitive, while others are not. What Are The Symptoms?The pain can differ from person to person. While some describe this pain as soreness, others might describe it as feeling tender, or like a shooting pain. Breast pain could be of various kinds, and are as followed:A dull painOccurs in one or both breastsRadiates to underarmsFeels sharp at timesOccurs alongside swellingFeels more intense in the nipple and area nearbyFor some menstruators, the pain could even be constant and could extend for days before they get their period.
