Because your boob should not feel like it’s auditioning for a role in a fever dream.
Mastitis while breastfeeding can feel brutal—like your boob suddenly decided to audition for a fever dream. If one breast feels painful, hot, swollen, and you’re hit with flu-like symptoms out of nowhere, you may be dealing with mastitis. The good news? It’s common, treatable, and doesn’t mean your breastfeeding journey is over.
Let’s break it down: what it feels like, how to treat it, and—yes—why continuing to nurse is actually part of the fix.
What Is Mastitis While Breastfeeding?
Mastitis is an inflammation of breast tissue that can involve an infection. It usually happens when milk gets backed up and bacteria sneak in—kind of like if a milk duct threw a tantrum and then invited germs to the party.
According to the American Academy of Pediatrics, mastitis affects about 1 in 10 breastfeeding people, most often in the first few weeks postpartum—but it can pop up any time during lactation.
Mastitis While Breastfeeding Symptoms to Watch For
Here’s what to watch for:
- A painful, hard, or hot lump in your breast
- Redness or streaking (like your boob is blushing in one spot)
- Flu-like symptoms: chills, fatigue, and body aches
- Fever of 101°F (38.5°C) or higher
- Feeling like you were hit by a Mack truck—emotionally and physically
If your breast is sore but you’re not running a fever, it might just be a clogged duct—still annoying, but easier to manage.
How Do You Treat It?
Step 1: Keep Breastfeeding or Pumping—Seriously
It might sound counterintuitive, but emptying your breast is key to healing. The World Health Organization recommends continuing to nurse frequently, even on the affected side, unless your doctor says otherwise.
Pro tip: Start feeds on the painful side when baby’s most eager—that’s when suction is strongest and can help clear the inflammation.
Step 2: Try These Home Remedies
-
- Gentle massage from the outer breast toward the nipple (yes, it may feel like you’re doing angry self-lymphatic drainage)
- Cold compress after feeds to reduce swelling
- Hydrate like it’s your full-time job
- If directly breastfeeding, position the baby’s chin toward the affected area when latching.
Step 3: Call Your Provider
If symptoms don’t improve within 24 hours—or if you feel really sick—don’t wait. You may need antibiotics. They’re safe for breastfeeding and often make you feel better fast.
Can I Still Nurse? (Spoiler: Yes!)
Yes, yes, and YES. Unless your doctor tells you to pause (rare), it’s safe to continue breastfeeding. In fact, stopping can actually make mastitis worse because milk that’s not moving = massive inflammation and angry boobs.
And no—your milk isn’t “bad” or infected. It might taste a little saltier to baby (wild, right?), but it’s still perfectly safe for them.
How to Avoid a Repeat Performance
- Empty your breasts regularly—don’t skip feedings or go long stretches early on
- Make sure baby is latching well (shallow latch = incomplete draining)
- Avoid tight bras or underwires that press on ducts
- Switch positions sometimes to drain different parts of the breast
- Rest and eat well (yes, you deserve a warm meal and a nap)
The Everyboob Bottom Line
Mastitis while breastfeeding is painful, frustrating, and unfair (like, wasn’t the fourth trimester already enough?). But with quick action, lots of milk flow, and maybe some antibiotics, you can bounce back—and keep breastfeeding, if that’s your goal.
Don’t tough it out in silence. Call your provider. Find an IBCLC (they can be life-changing). Text your group chat. Pop into the Everyboob app. Because you deserve care too, mama—not just your baby.
