I am 59, been post menopausal for nearly 10 years and I get hormone pellet implants every 14 weeks along with taking a daily prescription similar to progesterone. I began having nipple soreness only on the left breast a few days ago and then last night I had some discharge. I don't feel any lumps and have mammograms annually. Luckily, I have an appt in a couple weeks to do blood work for my next pellet implant. After reading everyone's comments, I feel better thinking this is about hormones because at each appt, the Dr asks if I've had any nipple soreness or discharge. I will provide an update after my appt.
