I have always had problems with lefty, the nipple doesn't flow as nicely as the right one and from time to time I have gotten blocked ducts. last week I got a really bad blocked duct, but with heat and a lot of nursing it cleared fine. Late yesterday all of a sudden my left nipple started hurting and today it REALLY hurts. It's not flowing very well at all and looks all cracked. I don't feel a lump yet, but the breast is full. I am at work today, so I can just pump. What's going on with lefty? Is there a blockage in the nipple or something? when I pump it just sort of drips out and hurts.
