This is probably not for the squeamish - sorry if TMI. DD2 is 11 months and down to one bf a day since I've been back at work, but we've been doing this for 2 or 3 months with no probs. But for the last couple of weeks I've had small, pus-filled lumps on one nipple. No milk comes out of them if I hand express, but if I squeeze them directly, they ooze pus and a bit of blood - like a spot basically. My breast is tender and feeding is a bit painful, but not excruciating. I had a similar looking lump when I was pg, but it was never sore. Any ideas? Should I see GP?
