<s>[INST] I got my nipples pierced in January, and I've gotten purple bumps outside the piercing, which if I squeeze, contain a white-ish yellow goop. And often, a bit of blood. If I squeeze it all out, and soak it in a saline solution, the bump goes away, as does the discolouration. What is happening here? [/INST] Hi.Thanks for your query. Read and understood your history of nipple piercing.Getting the bumps, pus on popping indicate that there is an infection and foreign body granuloma formation . The treatment is:Get a course of an antibiotic and anti-inflammatory medicines, if successful continue applying medical grade spirit or Liquid povidone iodine. . I hope this helps. If not get the ring removed and see the results. </s>
