My little guy has been breast feeding perfectly since day one...or so I thought. In the past 2 weeks I have been having a very painful left nipple when he latches and throughout. I don't have any cracking and I believe he is latching correctly, I've watched several videos. I could definitely be wrong though. I've found laying down is the best way to go, this doesn't hurt as bad. I also believe I have a blocked duct on the left side. It feels like a knot on the bottom of my breast. I've tried several suggestions such as warm compress, cold gel packs, and massaging. In between each feedings my nipples are still very sore. I don't know if they should be "toughen up" by now or not. I want to completely empty out the milk on the left side each time, I just find it very painful. This is probably all over the place but any suggestions would be wonderful!
