I thought it was mastitis but my breast isn't red/hot & I don't feel unwell. But my breast is full and hard on one part, it feels sore but I'm struggling to drain it, I think DD is struggling with it too and seems to be fussing about it (11 weeks). I've tried hand expressing and I have a electric pump but both don't seem to get much out. Works fine with other breast where I can express a full feed. I can get enough out to make it feel ok, but then it just fills back up. Any help/advice please
