Are you talking about cramping when feeding or sore nipples?
I had BAD cramps for the first week only when feeding, so after a week they were almost gone.
Sore nipples should get better in a few days if baby is latching on right
Most of the first week was awful. She wasn’t latching correctly so it caused blisters. We are getting it down now, still hurts the first minute or so but then it doesn’t the last couple of days.
