How to Treat a Clogged Milk Duct: What Actually Helps (and What to Skip)
A clogged milk duct happens when swelling and inflammation in the breast press on a milk duct and slow milk flow. It is not caused by milk being physically stuck. Treatment works best when it focuses on calming inflammation, supporting lymphatic drainage, and helping the nervous system relax, rather than using aggressive massage or constant pumping. Ice, gentle lymphatic techniques, and supportive feeding strategies can help relieve pain and swelling. Pelvic health physical therapists can help by using gentle hands on techniques, addressing posture and feeding positions, supporting nervous system regulation, and working alongside lactation and medical providers to reduce symptoms and prevent recurrence or progression to mastitis.
If you are breastfeeding or pumping and notice a tender lump, swelling, or pain in one area of your breast, you may be dealing with a clogged milk duct. This is very common, especially in the early postpartum period, but it can happen at any point during lactation.
Clogged ducts are uncomfortable and often stressful. Many parents worry they are doing something wrong. Others feel pressure to push through pain to clear the duct as quickly as possible. Unfortunately, a lot of advice still circulating can make symptoms worse.
Our understanding of how to treat a clogged milk duct has evolved. Current evidence supports a gentler and more effective approach. Let’s walk through what is actually happening in the breast and how to support healing, and where pelvic floor physical therapy fits into care for clogged ducts and mastitis.
What Is a Clogged Milk Duct?
A clogged milk duct is not milk physically stuck inside a duct.
Current research shows that clogged ducts are caused by localized inflammation, meaning irritation and swelling in the breast tissue. This swelling presses on a milk duct and limits milk flow. That pressure is why the area often feels firm, tender, or sore.
This distinction matters. When treatment focuses on forcing milk out through aggressive massage or excessive pumping, inflammation can increase. When treatment focuses on calming the tissue and improving fluid movement, milk flow often improves naturally.
Common Symptoms of a Clogged Milk Duct
Clogged milk ducts often present as:
A tender or painful lump in one area of the breast
Localized firmness or swelling
Discomfort during feeding or pumping
Skin that feels warm or appears mildly red
Symptoms limited to one spot in the breast
Usually no fever or flu like symptoms
If symptoms are localized and you feel well overall, the issue is typically inflammatory rather than infectious.
What Causes a Clogged Milk Duct?
Clogged ducts usually develop when milk flow is disrupted and inflammation builds up. Common contributors include:
Infrequent or irregular feeding or pumping
Oversupply or hyperlactation, meaning the body produces more milk than is being removed
Excessive pumping or aggressive expression that irritates breast tissue
Poor latch or infant oral restrictions, such as tongue or lip ties
Compression from tight bras, baby carriers, or sleeping positions
Stress and nervous system overload
Aggressive breast massage
Clogged ducts are rarely caused by one factor alone. They often reflect multiple stressors affecting the breast, posture, nervous system, and feeding mechanics.
How to Treat a Clogged Milk Duct
Treat It as an Inflammatory Condition
The most important principle in treating a clogged milk duct is understanding the goal.
The goal is to reduce inflammation and swelling, not to force milk out.
When inflammation decreases, the duct is no longer compressed. Milk flow often improves without aggressive intervention.
Ice Is Often More Helpful Than Heat
Clogged ducts, engorgement, and mastitis are inflammatory responses.
Mastitis is breast inflammation that can cause pain, redness, and sometimes fever. Some cases are infectious and some are not.
Heat increases blood flow and can worsen swelling. Ice causes vasoconstriction, meaning blood vessels narrow, which helps reduce swelling and pain.
What I recommend:
Use ice with a cloth barrier for up to 20 minutes
Repeat as needed throughout the day
A warm shower for your neck or upper back is fine
Avoid prolonged heat directly on the breast
Gentle Lymphatic Drainage
One of the most effective ways to treat clogged milk ducts is gentle lymphatic drainage.
The lymphatic system is part of your immune system. It helps move excess fluid, waste, and inflammatory byproducts out of tissues. When lymphatic flow slows down, swelling builds.
Gentle lymphatic drainage can:
Reduce breast swelling
Decrease pain and tenderness
Improve milk flow
Support healing without irritation
This technique should feel very light. Think skin movement, not muscle massage. Deep pressure or painful techniques can increase inflammation and delay relief.
Reverse Pressure Softening to Support Latch
Swelling around the areola can make it harder for your baby to latch or for a pump flange to fit comfortably. Reverse pressure softening can help temporarily reduce that swelling.
This technique involves:
Gentle inward pressure around the areola
Do this for one to three minutes
Performing before feeding or pumping
This can improve latch, milk transfer, and comfort. It is especially helpful during engorgement or early clogged duct symptoms.
Support Your Nervous System
Milk letdown relies on oxytocin, a hormone that helps milk release from the breast and supports bonding and calm.
Oxytocin release is strongly influenced by the nervous system. Pain, stress, anxiety, and feeling rushed can interfere with letdown and contribute to clogged ducts.
Supporting the nervous system may help:
Improve milk ejection
Reduce inflammation
Make feeding feel more manageable
Slow breathing, humming, gentle neck or jaw release, and a calmer feeding environment all support the parasympathetic nervous system. This is the part of the nervous system responsible for rest and healing.
What to Avoid When Treating a Clogged Milk Duct
Some well intentioned advice can worsen symptoms. Try to avoid:
Aggressive or painful breast massage
Digging into a lump
Prolonged heat on the breast
Constant pumping to fully empty the breast
Tight bras, restrictive clothing, or compressive baby carriers
Treatment should feel supportive, not forceful.
When Does a Clogged Milk Duct Become Mastitis?
Mastitis exists on a spectrum. Not all mastitis is infectious. Some cases are inflammatory and respond well to supportive care.
Seek medical care if you experience:
Fever, chills, or flu like symptoms
Worsening or spreading redness
Increasing pain
Symptoms that do not improve within 24 to 48 hours
A sudden drop in milk supply
Early care can often prevent progression and reduce the need for antibiotics.
How Physical Therapy Can Help with Clogged Milk Ducts
Pelvic health physical therapy can be a supportive and non invasive option for clogged milk ducts and mastitis prevention.
Care may include:
Gentle lymphatic drainage
Nervous system regulation techniques
Postural and rib mobility assessment
Education on feeding positions and body mechanics
Kinesiology taping to support lymphatic flow
Therapeutic ultrasound when appropriate
Physical therapy addresses the whole system. The goal is not just symptom relief. It is reducing recurrence and supporting long term breastfeeding comfort.
Preventing Recurrent Clogged Milk Ducts
Prevention often focuses on:
Supporting milk removal without over pumping
Reducing sustained compression to breast tissue
Improving posture and feeding mechanics
Managing oversupply thoughtfully
Addressing stress, sleep, and mental health
Collaborating with lactation and medical providers
When the whole system is supported, clogged ducts are less likely to return.
