Every month, so many women experience PMS differently — some run hot, others feel cold and exhausted, and some seem to catch every cold that goes around. In TCM, we know there's no single pattern behind premenstrual syndrome. Could someone walk us through the main diagnostic patterns? I'm especially curious how Kidney Yang Deficiency, Yin Deficiency with Empty Fire, and even Wei-Qi presentations might show up in a gynecological context. Thank you!
