Due to a Breast injury while lactating, I have become suseptable to Plugged Ducts, about one per month. Only while taking Lecithin do I not experience this. After starting Lecithin, I had one more PD, then no more until I went off Lecithin. After restarting, I had one more PD, then am free from PD so far. New BF Answerbook, pg 424 talks about dosing. OB had ultrasound performed on site of injury, and nothing abnormal was found. Just Enlarged ducts! Dayna Williams LLL Leader
