When you start breastfeeding, is it normal for a lymph node in your armpit to form rock hard and painful? I’m only day four of breastfeeding now and yesterday I woke up to my breasts engorged and painful and a lump in my armpit that is the same as well. I can’t get either of them to soften up and not be as painful as they are now. Is this normal? Is there something I can do or will it just go away on its own?
