Some women sometimes suffer an infection of the breast when they are breastfeeding. The breast infection is called Mastitis, which is caused by the S. aureus or the Streptococcus agalactia bacteria.
Breastfeeding mothers often experience having cracked nipples and plugged milk duct, causing the milk to backup. Bacteria that are on the skin surface or in the baby’s mouth could enter the mother’s breast through the cracked nipple, causing Mastitis.
When you have a breast infection, you will notice a painful lump in the breast, abnormal swelling making one of your breasts larger than the other, and a nipple discharge containing pus. Your breast feels warm, itchy, and painful while breastfeeding. You’ll also have a fever and experience flu-like symptoms. You should make an immediate appointment with your doctor if you experience these symptoms.
