Sore breasts
There are several possible causes of breast pain. If the pain is not resolving after trying to manage the issue on your own, contact a breastfeeding professional (external link) right away.
Engorgement
In the early days of breastfeeding, your breasts may swell up with milk and become tender. This is called engorgement.
Your breasts produce more milk than your baby requires to ensure they get enough. Your body will gradually adapt to meet your baby’s needs.
Feeding your baby early and often can help prevent and relieve this discomfort. Feed your baby according to their hunger cues (external link). Don’t limit the frequency or length of her feeds.
Sometimes babies find it hard to latch because of the swelling. If this happens:
Discomfort from engorgement should only last for a couple of days. Contact a breastfeeding professional (external link) if the engorgement is not improving.
Lumps or Reduced Milk Flow
Hard lumps in lactating breasts are often due to inflammation or swelling in the breast tissue. This inflammation and swelling can be caused by having too much breastmilk and/or an imbalance of the good and bad bacteria in the breastmilk. Both can lead to a narrowing of the milk ducts, making it more difficult for the breastmilk to flow through.
The inflammation and narrowed milk ducts can cause breasts to be firm and tender or painful. These symptoms may occur in one part of a breast or can spread to the entire breast.
What can you do (recommendations):
- Continue to breastfeed your baby on demand (do not do extra feedings/pumping to try to reduce inflammation or “empty the breast” as it can increase your milk supply and worsen the problem).
- Minimize use of breast pumps and nipple shields if possible,
- Apply ice or cold compresses (avoid applying heat to the breast).
- Talk to your health care provider about taking medications to help reduce inflammation (e.g., ibuprofen and sunflower lecithin or soy lecithin) and for pain (e.g., acetaminophen).
- Do not use deep breast massage or vibrating devices to try to “break up a clog”.
- Wear an appropriately fitting, supportive bra.
Mastitis
If inflammation in the breast worsens, inflammatory mastitis can develop.
Symptoms of inflammatory mastitis include:
- Redness of an area of the breast
- Swelling of the breast
- Pain
- Fever and/or chills, and
- Increased heart rate
If your symptoms are mild and focused on one specific area of the breast, try the recommendations listed above to treat inflammatory mastitis. If after 24 hours your symptoms are not improving or getting worse, contact your health care provider as you may have a bacterial infection that requires antibiotics to treat.
NOTE: inflammatory and bacterial mastitis are not contagious and are not dangerous to your infant. There is no need to pause or stop breastfeeding.
If you think you may have breast inflammation or mastitis, speak with your health care provider and/or a breastfeeding professional (external link) to help address the underlying causes and prevent it from worsening or reoccurring.
Thrush (yeast) infection
Thrush can also cause burning or shooting pain in the breast. Parents with thrush may also experience red, shiny, itchy or sore nipples. The pain may happen between feedings.
If you think you may have thrush, speak with your health care provider and/or a breastfeeding professional (external link).
