Breast pain during breastfeeding is common, especially in the first few weeks, and most causes are easy to treat. The usual reasons are a shallow latch, overfull breasts (engorgement), a blocked milk duct, sore or cracked nipples, and mastitis. Most mothers feel better with frequent feeding, a better latch, warm and cold compresses, and simple pain relief. Pain with fever, a red hot patch or a lump that does not go away needs a doctor within a day.
Feeding your baby is not supposed to hurt for weeks on end. This guide explains why breast pain during breastfeeding happens, what different symptoms mean, the remedies that actually help, and when to get medical care.
Mild tenderness in the early days is normal. Ongoing breast pain during breastfeeding usually has a clear cause, and fixing the latch and keeping milk moving solves most problems.
Is Breast Pain Common During Breastfeeding?
Yes. Breast tenderness during breastfeeding is very common in the first days and weeks, as milk comes in and you and your baby learn to feed together. Pain that lasts beyond the first couple of weeks, gets worse, or comes with fever is not something to ignore.
According to NHS advice on breast pain and breastfeeding, positioning and attachment are among the most common causes of breast and nipple pain, and small changes to how your baby latches can make feeding much more comfortable.
Why breast pain during breastfeeding happens
Your breasts change quickly after birth. Around day two to five, milk production increases sharply. The breasts fill with milk, blood and fluid, so they can feel heavy, warm and tender. As your supply settles to match your baby’s needs, this fullness usually eases.
Ongoing breast soreness during breastfeeding usually comes from one of three problems:
- Milk is not draining well, because of a shallow latch, missed feeds or long gaps between feeds
- The nipple is being damaged by a latch that is too shallow or by the baby’s tongue or jaw position
- Inflammation or infection has developed in the breast tissue or nipple
What Causes Breast Pain During Breastfeeding?
These are the most common causes, from the mildest to those that need medical treatment.
| Cause | What it feels like | Typical timing | First steps |
|---|---|---|---|
| Engorgement | Both breasts hard, tight, heavy and warm; nipple may flatten | Days 2 to 5, or after a long gap between feeds | Feed often, express a little to soften, cold compress between feeds |
| Shallow latch | Pinching or sharp pain at the start of feeds | Any time, most often early on | Re-latch with the baby’s mouth wide open |
| Sore or cracked nipples | Burning or stinging at the nipple, sometimes bleeding | First weeks | Fix the latch, air-dry nipples, apply a little breast milk |
| Blocked milk duct | A small, tender lump in one area; you feel well | Any time | Keep feeding from that side, warmth before feeds, cold after |
| Mastitis | Hot, red or darker, swollen area, flu-like aches, fever | Any time, most often in the early weeks | Keep feeding, rest, pain relief, see a doctor if not better in 12 to 24 hours |
| Breast abscess | Tense, very painful lump that does not settle, ongoing fever | After untreated mastitis | Urgent medical review; may need drainage |
Engorgement
Engorgement happens when the breasts become overfull. The NHS notes that the breasts can feel hard, tight and painful, and the nipple can become stretched and flattened, making it harder for the baby to latch.
Blocked milk duct
A blocked duct is a section of the breast that is not draining properly. It feels like a small, tender lump. Treating it quickly matters, because an untreated blocked duct can lead to mastitis.
Mastitis and breast abscess
Mastitis is inflammation of the breast tissue, sometimes with infection. It causes a hot, painful, swollen area and flu-like symptoms. If mastitis does not settle, a pocket of pus called a breast abscess can form. An abscess does not clear with feeding alone and usually needs drainage.

What Your Breast Pain During Breastfeeding Is Telling You
The pattern of pain is often the best clue to its cause.
One breast pain during breastfeeding
Pain in only one breast usually points to a local problem on that side, such as a blocked duct, early mastitis or a damaged nipple. Offer the sore side first so it drains well.
Breast pain during breastfeeding with no lump
Pain without a lump is often caused by engorgement, a shallow latch or nipple damage. A deep, burning or shooting pain that continues after feeds, with sore nipples, can sometimes be a sign of a nipple or breast infection, including thrush. If nipple pain does not improve once the latch is corrected, ask a doctor to check.
Breast pain and lump during breastfeeding
A tender lump is most often a blocked duct. It should soften within a day or two with frequent feeding and warmth. A lump that grows, becomes red and hot, or stays for more than a few days needs a doctor’s check, as it could be mastitis, an abscess or, rarely, something unrelated to breastfeeding. Our guide to breast lumps explains other possible causes.
Breast hardness and pain during breastfeeding
Hard, painful breasts on both sides usually mean engorgement. Hardness in one wedge-shaped area, especially with redness, is more typical of mastitis.
Pinching breast pain during breastfeeding
A pinching or squeezing pain at the start of a feed usually means the baby is latched onto the nipple rather than taking a big mouthful of breast. If the nipple looks flattened or creased like a new lipstick after a feed, the latch is too shallow.
Heavy breast pain during breastfeeding
A heavy, dragging ache between feeds is common when the breasts are very full. Feeding more often and wearing a soft, supportive bra usually helps.
Breast pain during breastfeeding and fever
Fever, chills or flu-like aches with a painful breast suggest mastitis. This needs prompt attention, especially if you do not feel better within 12 to 24 hours of self-care.
Breast and nipple pain during breastfeeding
When both the breast and nipple hurt, the cause is often a poor latch that damages the nipple and leaves milk behind in the breast. Fixing the latch usually helps both problems at once.
Remedies for Breast Pain During Breastfeeding
Keep feeding often, improve the latch, use warmth before feeds and a cold compress after, take paracetamol or ibuprofen if needed, and wear a soft, non-restrictive bra. Do not stop breastfeeding suddenly.
Try these steps to ease breast pain during breastfeeding at home:
- Check the latch. Bring your baby to the breast with a wide-open mouth, chin touching the breast and more of the lower areola in the mouth than the upper.
- Feed often. Aim to feed whenever your baby shows hunger cues, usually 8 to 12 times in 24 hours in the early weeks.
- Start on the sore side if one breast is fuller or has a lump, as babies often suck more strongly at the start.
- Use warmth before feeds for a few minutes to help milk flow, but avoid long, hot soaks.
- Apply a cold compress after feeds. The NHS suggests a cold cloth for about 10 minutes every hour for mastitis pain.
- Express just enough to feel comfortable if your breasts are very full. Expressing too much tells your body to make more milk.
- Massage gently, stroking lightly towards the armpit and nipple. Avoid deep, firm pressure, which can bruise tissue and worsen swelling.
- Take simple pain relief. Paracetamol and ibuprofen are generally compatible with breastfeeding. Avoid aspirin.
- Rest and drink to thirst. Tiredness and illness make pain feel worse.
How to prevent breast pain during breastfeeding
- Get help with the latch in the first days, before problems build up.
- Avoid long gaps between feeds, and do not suddenly drop feeds.
- Wear a supportive bra without underwire, and avoid tight straps or sleeping on your front.
- Change feeding positions so different areas of the breast drain well.
- Act early on a tender lump or a sore nipple instead of waiting.
When Should You See a Doctor?
Most breast pain during breastfeeding improves with self-care, but some signs need medical attention. The NHS advises seeing a doctor if mastitis symptoms do not improve within 12 to 24 hours of home treatment. The Mayo Clinic notes that when antibiotics are needed, a course of about 10 days is common, and that continuing to breastfeed is safe and helps clear the infection.
See a doctor the same day if you have:
- A fever, chills or flu-like aches with breast pain
- A red, hot or swollen area that is spreading
- A lump that grows, feels tense or does not settle within a few days
- No improvement 48 hours after starting antibiotics
- Pus or blood from the nipple, or a cracked nipple that will not heal
- Severe pain that stops you feeding

Frequently Asked Questions
Should I stop breastfeeding if my breast hurts?
No. Stopping suddenly can make breasts fuller and pain worse. Keep feeding or expressing from the sore side unless a doctor advises otherwise.
How long does breast pain during breastfeeding last?
Early tenderness usually eases within one to two weeks. Engorgement settles in a day or two with frequent feeding, and a blocked duct often clears within 48 hours.
Can breast pain during breastfeeding affect my milk supply?
Pain itself does not reduce supply, but feeding less because of pain can. Keeping milk moving protects your supply.
Is breast pain during breastfeeding a sign of cancer?
Rarely. Most breast pain during breastfeeding is caused by feeding problems or infection. A lump that stays after feeding problems are treated should still be checked.
