What's wrong with aunt's chest pain?

During menstruation, due to changes in hormone levels, breast tissue and acinar tissue will swell, so showing chest pain is a normal physiological phenomenon, generally after the end of menstruation can be relieved. During this period, be careful not to press hard or squeeze the breast. If after menstruation, chest pain is still not relieved, can go to nail breast surgery for breast ultrasound examination, because if there are breast cysts, breast fibroma or breast hyperplasia, will also show chest pain.
