Ok, so if it's not red then what else could it be? It just started this morning when I woke up and hurts when LO nurses on that side

Redness starts at the nipple and goes up if it's more than halfway up your boob then you need to go to ER but you can pump it out as long as it's not like that and your boob will really hurt and fever like flu symptoms

Redness sore to the touch extra hot fever
