Breast pain is one of the most common reasons mothers worry about breastfeeding, and one of the most common reasons they stop earlier than they planned. The good news is that most breast pain has a clear cause and a simple fix. This guide explains what usually causes the pain, what you can do at home, and which signs mean you should see a doctor.
The short answer
The best way to relieve breast pain during breastfeeding is to find the cause and treat it at the source. In most cases that means four things:
- Check your baby's latch and position, because a poor latch is the most common cause of sore nipples.
- Keep feeding often so the breast does not stay full.
- Use comfort measures such as a short warm compress before feeding and a cold compress after.
- Take a safe pain reliever if needed, and see a doctor if you have a fever or a red, hot, hard area.
Is some pain normal?
Some tenderness is common in the first days. Sore nipples are most common around days 3 to 7 of breastfeeding, and engorgement can happen while your milk supply is settling in. But breastfeeding should not keep hurting throughout every feed. If the pain is strong, lasts more than a week or two, or gets worse, something can usually be improved.
Common causes of breast pain while breastfeeding
- A shallow latch: usually the main reason for sore or cracked nipples.
- Engorgement: breasts that become too full, hard, and tender when milk comes in or when feeds are missed.
- A blocked milk duct: a tender lump, sometimes feeling like a bruise.
- Mastitis: inflammation of the breast, sometimes with infection, which can come on quickly.
- Thrush: a yeast infection that can cause burning or shooting pain.
- Tongue-tie or feeding difficulties that stop your baby from emptying the breast well.
- Too much milk (oversupply) that makes it hard for the baby to cope with the flow.
What helps: step by step
1. Check the latch and position
If feeding hurts, start here. Signs of a good latch include a wide-open mouth, more of the areola in the lower part of your baby's mouth than the upper part, a chin pressed into the breast, and slow, deep sucks. If you need to take your baby off the breast, slide a clean finger into the corner of the mouth to break the suction first. If it still hurts after you adjust, ask a midwife, health visitor, or breastfeeding counsellor to watch a feed. A small change in position often makes a big difference.
2. Keep feeding, and do not skip feeds
Do not shorten feeds or skip them to avoid pain, because this can lead to engorgement and blocked ducts. Feed whenever your baby shows hunger signs. If a nipple is very sore, you can offer the less painful side first, then switch. If it is too painful to latch at all, express your milk by hand or with a pump until you get help, so the breast does not stay full.
3. Ease engorgement
- Take a warm shower or apply a warm compress for a few minutes before feeding to help the milk flow.
- Hand express a little milk to soften the area around the nipple, so your baby can latch more easily.
- After feeding, use a cold compress or a cold pack wrapped in a cloth for 10 to 15 minutes to reduce swelling and pain.
- Express only enough to feel comfortable. Emptying the breast completely tells your body to make even more milk.
4. Treat a blocked duct early
- Continue breastfeeding responsively if you can do so comfortably; do not try to force the breast to empty.
- Use a cold pack wrapped in cloth to help reduce swelling and discomfort.
- Avoid deep massage, squeezing, or forceful attempts to push a lump toward the nipple, as these can worsen inflammation.
- Wear a comfortable, supportive bra that does not press tightly on the breast.
A tender, swollen area may reflect inflammation rather than a simple plug. Avoid deep massage or trying to force milk through the area. If symptoms worsen, you develop a fever, or you feel unwell, contact a healthcare professional promptly.
5. Care for sore or cracked nipples
- After each feed, express a few drops of breast milk and gently rub it onto the nipple, then let it air dry.
- Use a nipple cream made for breastfeeding, such as purified lanolin, or a hydrogel pad. Ask a pharmacist if you are unsure.
- Keep nipples as dry as possible between feeds, and change damp breast pads often.
- Avoid soap, alcohol-based products, or perfumed creams on the nipples.
6. Use pain relief if you need it
Paracetamol and ibuprofen are generally considered compatible with breastfeeding when used as directed on the label. Ibuprofen can also help with inflammation. If you are unsure, or if you have a health condition or take other medicines, ask a pharmacist or doctor first.
What to avoid
- Do not stop breastfeeding suddenly without a plan, but do not force painful feeding or extra pumping. Seek professional advice if feeding is too painful.
- Avoid prolonged heat on a red, swollen breast; a wrapped cold pack may be more helpful for swelling.
- Do not massage a sore area hard or squeeze a lump.
- Do not use herbal remedies or creams on your nipples without asking a professional.
Mastitis: signs and what to do
Mastitis means inflammation of the breast. It often starts with a blocked duct that is not relieved, and it can come on suddenly and get worse quickly. Signs include:
- A red, hot, swollen, or very tender area on the breast
- A hard lump or a wedge-shaped patch
- Fever (38°C / 100.4°F or higher), chills, or flu-like aches
See a doctor the same day if you think you have mastitis. Some cases improve with frequent feeding and rest, but others need antibiotics. It is usually recommended to keep breastfeeding, because it helps the breast drain and recover. Your milk is still safe for your baby, and mastitis is not contagious. Untreated mastitis can lead to an abscess, which may need to be drained.
Thrush: a different kind of pain
Burning, stinging, or shooting nipple or breast pain can have several causes, and pain alone does not confirm thrush. If you notice persistent pain, nipple changes, or white patches in your baby’s mouth, ask a doctor or lactation professional for an assessment before using antifungal treatment. Treatment depends on the cause, and your baby may also need evaluation.
When to see a doctor right away
- You have a fever with a red, hot, or painful area on the breast
- A hard lump that does not improve within 24 to 48 hours of feeding and the steps above
- Pus, or blood in your milk that is not coming from a cracked nipple
- Red streaks on the skin, or you feel very unwell
- Pain that is severe, or that gets worse even with treatment
- Your baby is feeding poorly, has fewer wet diapers, or is not gaining weight
- A lump that stays after the pain has gone
Frequently asked questions
Can I keep breastfeeding if I have mastitis?
Yes, in most cases. Continuing to breastfeed helps the breast drain and speeds up recovery. Ask your doctor if you are not sure, especially if you are given medication.
Is heat or cold better for breast pain?
A short period of warmth before a feed can help the milk flow. Cold after a feed helps reduce swelling and pain. If the breast is red, hot, and swollen, cold is usually the better choice than long periods of heat.
How long does engorgement last?
Early engorgement often eases within a few days as your supply adjusts to your baby's needs. If it lasts longer, or the breast stays hard and painful, ask for feeding support.
Should I pump to relieve the pain?
Express only enough to feel comfortable, or if your baby cannot latch. Pumping more than needed can increase your milk supply and keep the problem going.
Is nipple pain a sign that I should stop breastfeeding?
No. Most breastfeeding pain improves with a better latch and the right support. Many mothers go on to breastfeed comfortably for as long as they wish.
