I just turned 50 years old in Sept. 2013. Just tonight, 01/26/2014, I discovered a very strange "greenish" tinted discharge coming from the "milk glands" in my left breast nipple. There was a tingling sensation, to which I rubbed my breast lightly, but it was more of an "itch" right in center of nipple. I removed my shirt, was grasping my nipple, to tilt it upward so I could see the center of the nipple, and this "green discharge" oozed out! Its like "ink"
