Sore nipples in the first days and weeks postpartum are usually the result of poor latch-on or baby's sucking technique. Sore nipples that persist beyond the early weeks postpartum or that occur after weeks or months of pain-free breastfeeding may have other causes, such as Candida Infection. Painful feedings are a signal that something's not right and you need to make a change.
Here are some of the tips that you can use:
A good commentary about preventing and fixing sore nipples - by Dr. William SearsUsually the breast feeding pain subsides with second week, but if the pain were to persist look for other reasons described in the next few links. The other causes for
severe breast pain during feeding can be excess of oxytocin that causes cramps in the boobs. Or you should verify if there is any
yeast infection that can lead to Mastitis. Infection can be dangerous since you can pass on that to your baby and
cause Thrush in your baby's mouth.
If no infection is found, try giving some Hot Compress or
Soothies Gel Pads or
apply Lanolin cream or express some breast milk to the nipple and allow them to dry. Good Luck!
