I've been nursing dd problem-free for more than a year (well, except for the initial latch difficulties), but the past couple of days the side of my breast has felt tender and today it's kind of splotchy red. There's no lump or hardness there, but it feels bruised. I consulted "The Womanly Art..." and from what it says it sounds like I might have a plugged duct, but none of the causes listed sound like they apply to me. Dd hasn't slowed down on nursing, I don't wear a constrictive bra.. nothing like that. So, does anyone have any idea what else it could be, or should I just treat it as a plugged duct?
