Good day everyone. My breast was full and sore at night, I fed my daughter, she sucked well but there were a few small lumps left and my breast hurt, so I fell asleep again and in the morning I fed her again with this breast, it became soft without lumps, but it hurt very much, even if not touched, the temperature rose to 37.3. A little later I fed her again with this breast, the pain started to subside, but the temperature went up to 38.1. What should I do? Can't squeeze with hands and suction doesn't work ? Should I lower the temperature or not? I'm drinking plain water.
