NIPPLES: pain and discharged

First of all 20 years old, single, deff not pregnant. 
Okay so there are white specs on my nipple and when I squeeze white pus comes out. It's kinda like popping a pimple, I brushed it off as blocked ducts because of sports bras. But now after I pop them it's pus like and underneath its waterey discharge and now my nipples are shooting with pain to the point it hurts to wear any clothing over them. Has anyone ever had this? Please help.
