What Is The Treatment For A Green Spot In The Nipple?

hi i am a female, 18 years of age. i had a greenish spot right next to my nipple. i tired squeezing it for months bt it would never pop. about 3 weeks ago,i popped it and a large amount of white solid came out as well as liquidy pus and a hair also spurted out. but even after popping it, it refills with pus every day and i keep popping it but its not working. i even used proactiv on it bt it was of no use. what should i do?
