Nipple Issue🥺😩 plz help

So I’ve had this bump on my areola for at least 2.5 years now. It’s the same color as my nipples, just a bump. When I squeeze it, a little bit of thick white stuff comes out? It’s never hurt besides for once about 6 months ago, it swelled up and hurt extremely bad, then calmed down and now there’s like 2 or 3 bumps all swelled up into one... and when I squeeze the same thing comes out except for in three different areas. (All very close to each other) It’s just super annoying... anyone know what this is? (To add, I’ve never been pregnant).
