I've been nursing and pumping for a little over a month now,and everything is going good. I had a slight drop in supply, so I started pumping more and taking Fenugreek. I can see that it is working, but I have a sharp pain that is stabbing in the left breast now. I didn't feel anything like it before when my milk was coming in or even when I felt engorged. It is only occasional and I have no fever, redness, swelling or anything that looks like mastitis, but I am concerned that it could be something else. I don't feel like it is correlated with the increase in production, but I'm not sure. It is there even after I pump or nurse, if it is a plugged duct what can I do about it?
