What happened to my aunt's chest pain?

The symptoms of chest pain before menstruation are due to the high estrogen level in the body before menstruation, which stimulates the development of breast tissue. It is a normal physiological phenomenon. Generally, after menstruation, the hormone level in the body decreases, and the symptoms of chest pain are relieved. If the symptoms persist, consider that it may be related to breast hyperplasia and need to go to the hospital. In addition, on the eve of menstruation, some women will show small abdominal bulge and emotional changes, which are normal physiological phenomena.
