I have one boob that hurts. I tried pumping after feeding LO and I barely got anything (jury is still out on if it's due to the pump though). LO has been rejecting this side and will only take it reluctantly but once he latches he seems fine. It is full though I can feel the weight and when I squished my boobs against my chest with my palms flat facing me (I didn't know how else to tell for sure) it is at least 2x the size of the other one which really squished down so I'm not imagining it. I can get a little milk to come out by hand expression so it's not clogged ducts I guess. Is this mastitis? Or can that only be determined by a doctor's visit? Why do these things always have to occur on a Friday afternoon LOL?
