Tenderness And Itching Around Right Breast Nipple, Oozing Of Little Black Liquid From Breasts. No Lumps. Concerning?

Hi,
I am a 40 yr old African American woman with no known history of breast cancer on either side of my family. That being said, I recently experienced some tenderness and itching around my right breast nipple. i noticed after a few days of my hand constantly going to that area of my body that I should probably look further into it. so I fully examined my breasts for lumps and felt none. Didn't really feel any significant amount of pain either, but there was this constant..discomfort. I began to squeeze my nipple on the right breast, and to my surprise, a little black bead of liquid oozed out! When I squeezed the nipple on the left breast, and it too was black. not green..black. not a significant amount comes out when squeezed and I really have to work for it to produce another sample, but still, I am very upset and apprehensive about it cause. I read online that it could be a known benign breast condition called Mammay Duct Ecstasia that could be treated with anti biotics, but Im still apprehensive. Please advise.
