My left breast is very sore and the skin is pinky red in patches, especially underneath, and I feel like I'm coming down with flu. I think it started because I only fed my son on the right this morning before I went to work...but there's been lots of days when he only feeds on one side in the morning and the other side in the afternoon without any problems, so I don't know why this time it would cause a plugged duct. And I'm not even sure if that's what this is. I had a plugged duct before (when he was 3mths) and I knew exactly where it was, in a very contained area and there was a hard lump. This time it's more like a general soreness. Does anyone have any experience/advice? Thanks.
