Plugged milk ducts in half the boob?!

Charlotte

I woke up in the middle of the night with bad pain in my right boob, far to the right. After nursing (30 minutes or so later) half of my breast was hurting. Can this be a plugged milk duct? Or several? This is my second baby and I’ve never experienced this before. I’m exclusively breastfeeding and my baby is 7 weeks old.
