F.W.
It could still be a plugged duct, that is not fluid, but dried, so therefore it wouldn't come out when aspirated. Isthere redness, soreness, sign of infection? Also, whenyou stop breastfeeding, hormones go crazy and it could just be normonal changes. I also have had cystic breasts, so have had many exams. The ultrasound will pick up things you can't even feel, so your doctor is trying to make sure. It may very well be resolved before the USN. Don't be worried.
