I've had a pea sized lump at the tip of my nipple for about a week. It changes in size and hardess sometimes. It was real painful at first while nursing, but I can nurse comfortably on that side now though the lump is still there. It's the same color as the rest of my nipple. I've tried all the normal stuff--moist heat, lanolin, frequent nursing, the "dangle"--nothing seems to affect it, though. Saw the doctor who says it's a plugged duct and put me on some antibiotics as a preventative measure. If it's just a plugged duct, though, I don't get why it hasn't cleared by now. There's no visible dried milk, but nothing comes out of that area when I hand express. Any ideas or possible solutions?
