This may be tmi.. but I'm worried about these bumps that have developed on the skin of my breasts, not the nipples. They sometimes itch, and today when I scratched them it seemed to get worse and multiply. I've been EBF for 4 !weeks. Also, when I scratched some of them a little pus has come out. They're almost like a cross between acne and bites. If anyone ha any insight on this I would appreciate it!
