Why do your nipples hurt while nursing?

Sore nipples are a common complaint among breastfeeding women, especially in the early weeks of breastfeeding. There are several reasons why your nipples may hurt while nursing:

1. Incorrect latch: The most common cause of sore nipples is an incorrect latch. When your baby is not latched on properly, they may be pulling on your nipple instead of sucking on the entire breast. This can cause pain and damage to the nipple.

2. Thrush: Thrush is a yeast infection that can affect the nipples and breast tissue. Thrush can cause pain, itching, and burning sensations in the nipples.

3. Vasospasms: Vasospasms are spasms of the blood vessels in the nipples. They can cause the nipples to feel cold, numb, or tingly. Vasospasms can also be painful.

4. Mastitis: Mastitis is an infection of the breast tissue. Mastitis can cause the nipples to become sore, red, and swollen.

5. Allergy or sensitivity: Some women may experience an allergic reaction or sensitivity to something in their baby's saliva, which can cause sore nipples.

6. Tongue-tie or lip-tie: A tongue-tie or lip-tie is a condition in which the frenulum, a piece of tissue that connects the tongue or lip to the floor of the mouth, is too short. This can restrict the baby's movement and make it difficult for them to latch on properly, leading to sore nipples.

If you are experiencing sore nipples while nursing, it is important to see a healthcare professional to rule out any underlying medical conditions and to get treatment for the pain.
