A. What you describe is a condition called galactorrhea (pronounced “guh-lak-tuh-ree-uh”), and is characterized by a spontaneous flow of breast milk in the absence of childbirth or a nursing child. Though uncommon, galactorrhea is most likely seen in women, but can also show up in men in rare instances. Possible causes of galactorrhea are many and may include: • Starting a new medication • Taking herbs such as nettle, fennel, thistle, anise or others • Drug use, particularly marijuana and opiates • Wearing clothing that irritates the breasts • Breast stimulation through sexual activity or very frequent self-exams
