Hi ladies! I had surgery in one breast a couple of years back to remove a couple of ducts that had intraductal papillomas in them. I have scar tissue along the areola and under the areola. I've had problems with breastfeeding and pumping from that breast. The other side produces 3-4 oz per session (sometimes up to 5 oz) while the breast where I had surgery produces 1 oz max! I pump at the max setting and I think that it's still having trouble accessing the milk ducts. I use the 30 mm breast shields. Do you think I should go up to the 36 mm shields because of the scar tissue? What have you guys done?
