Mastitis and Clogged Ducts: Signs, Treatment, and When to Call for Help

Breastfeeding has many joys, but sometimes it comes with challenges like clogged ducts or mastitis. These issues are common, and while they can be uncomfortable (or even painful), they’re usually treatable with the right steps and support.

What Is a Clogged Duct?

A clogged or “plugged” duct happens when milk doesn’t drain fully from part of the breast. This can create a firm, tender lump and localized discomfort. Sometimes the skin over the area looks a little red.

What helps:

• Continue breastfeeding or pumping on the affected side
  
  

• Use gentle massage and warm compresses before feeding
  
  

• Try different nursing positions so baby’s chin points toward the clogged area
  
  

• Make sure bras and clothing aren’t too tight
  
  

What Is Mastitis?

Mastitis is inflammation of the breast, often caused by a clog that didn’t resolve. It can feel similar at first but usually comes with more intense symptoms:

• Red, hot, swollen area on the breast
  
  

• Flu-like feelings: fever, chills, body aches
  
  

• More significant pain or tenderness
  
  

When to Call for Help

If you have a fever, worsening symptoms, or feel very unwell, it’s time to reach out to your healthcare provider. Mastitis may require antibiotics to clear an infection.

How to Prevent Recurrence

• Ensure your baby has a deep, effective latch
  
  

• Alternate feeding positions to help drain all areas of the breast
  
  

• Avoid skipping feeds or going too long between pumps/nursing sessions
  
  

• Stay hydrated and rest when possible (we know, easier said than done!)
