Sore, hard, large lump

Chelsea

My son is 7 weeks old. Three weeks ago I had a nipple bleb, two weeks ago I had mastitis, this week I now have a sore, hard, large lump about the size of a golf ball located under my boob by my armpit. I’ve tried different feeding position for bubs, massaging it out in a hot shower and while expressing as feeding which does seem to drain it to a large marble size but it fills up incredibly quickly again. I’m not feeling sick at all, just very sore.

I will be visiting the doctors but just wondering if anyone else has experienced this and can share their story?

I’m wondering whether it’s still my mastitis that hasn’t gone away fully or just a blocked milk duct or a breast abscess..
