Women experiencing amenorrhea may also feel pain in their nipples, which is generally considered a normal, temporary physiological reaction. This occurs because, prior to the cessation of menstruation, the secretion rate of endogenous estrogen decreases, and the breast tissue cannot quickly adapt to this change, leading to breast pain. If the pain persists or becomes severe, it is also important to watch out for pathological diseases, such as breast hyperplasia and other conditions. Do not squeeze the breasts with your hands, avoid wearing tight bras, and timely breast ultrasound examinations should be conducted to guide treatment based on the results.
