If you get a blocked duct, can you unplug by pressing or massaging it?

Yes: and see below. Apply moist heat before nursing (compresses, warm shower or bath, or leaning over a sink full of warm water). A heating pad on a low between feedings, especially during the night can help dissolve the clog.Pain medication if you need it. Advil (ibuprofen) or Motrin or tylenol- for pain and fever. Encourage nursing frequently (at least every two hours) and vary the nursing positions so pressure will be varied.
