Other reasons for sore boobs when breastfeeding
Let's run through some other common causes and conditions that can lead to sore nipples or overall breast pain when breastfeeding.
Nipple blanching (vasospasm)
Also known as vasospasm, this happens when blood flow is restricted to the nipple area. It can be caused by a shallow latch or Raynaud's syndrome (a condition that affects blood supply). This can be painful or cause a burning sensation, and the nipple may look white.
If you experience nipple blanching, it's best to avoid cold exposure, stay warm when breastfeeding, and apply a warm compress immediately after feeds.
Dry skin conditions (like eczema)
If you have underlying eczema, you might be more prone to breastfeeding discomfort and nipple pain. Dry skin conditions like eczema can develop around the nipple and cause discomfort that might affect breastfeeding.
Irritants from soaps, perfumes, or detergents can cause skin irritation. These can also sometimes worsen sore nipples if they're already cracked, so it's best to avoid these if you have irritated, dry skin.
Breast engorgement
Breast engorgement happens when your breasts become sore because they're overly full of breast milk. This can happen when your breast milk first comes in, or at any point in your feeding journey. If you experience breast engorgement, you should continue to breastfeed your baby if you can. Use warm heat packs or have warm showers before feeding to provide some relief.
Milk blister (bleb)
A milk blister or bleb develops when a small piece of skin grows over a milk duct and causes it to become blocked. This can be painful and appears as a white, yellow, or clear 'dot' on the areola or nipple. These can last for several days to weeks but should clear when the skin breaks in the affected area.
Blocked milk ducts
When the ducts in the breast aren't drained properly, this can lead to the development of a blocked milk duct. This can present as a hard lump in the breast that feels sore or tender. To help, you can continue to feed regularly, use a warm compress, and gently massage the lump to help unblock it so that your breast milk can flow comfortably again.
Mastitis
Mastitis is inflammation of the breast that's caused by blocked milk ducts or an infection. It causes the breast to become inflamed, appear darker in colour, and can be painful. It can also lead to a breast abscess that may require treatment from your doctor.
Thrush
Nipple pain can sometimes be caused by a thrush infection. Thrush occurs when nipples become damaged and can be painful, often feeling like a burning sensation or shooting pain in the nipple after breastfeeding. It can sometimes also develop in the mouth of the baby and needs to be treated with a prescription medication from a GP.
