My symptoms are tender breasts nipples sore to touch groin pain?

Hormonal: If both breasts are sore and tender it points to hormonal reactions, especially if around period time. If breasts are usually lumpy, fibrocystic changes may predispose you to more breast discomfort. Avoid caffeine. Groin pain could be of pelvic origin. Endometriosis and pelvic congestion act up around period time. Pelvic inflammatory disorders may be a cause. Your gynecologist can advise you best.
