Blocked milk ducts can cause tenderness, redness, and a hard or sore area of the breast. Many also experience flu-like symptoms such as fever, chills, and malaise. Symptoms often appear suddenly and can make you feel quite unwell.
What is a blocked milk duct?
A blocked milk duct means that milk is not being emptied from the breast as it should, which can lead to inflammation of the breast tissue.
Blocked milk ducts are common during the breastfeeding period and occur particularly in the first few weeks after giving birth, when breastfeeding is still being established.
What are the symptoms of a blocked milk duct?
Common signs of a blocked milk duct are:
- A tender or painful area on the breast
- A hard lump or induration
- Redness on the skin
- A feeling of heat in the breast
- Fever
- Chills
- Malaise or body aches
Many describe it as feeling like you are getting sick very quickly.
How does a blocked duct feel?
A blocked milk duct can feel like an aching or throbbing pain in the breast. The area may be warm, tight, and sensitive to touch.
At the same time, you may feel tired, chilly, and run-down, much like with the flu.
How quickly do the symptoms appear?
For many, the symptoms come on quite suddenly. You can feel completely fine one moment and then develop a fever, chills, and breast pain a few hours later.
What can cause a blocked milk duct?
Blocked milk ducts can occur if, for example:
- The breast is not emptied sufficiently
- The breastfeeding pattern changes rapidly
- A breastfeeding session is skipped
- The baby does not have an optimal latch
- The breast is subjected to pressure, e.g., from a tight bra
What can you do about a blocked milk duct?
Many find that the following helps:
- Breastfeeding or pumping regularly
- Offering the affected breast first when breastfeeding
- Resting as much as possible
- Drinking plenty of fluids
- Gently massaging the area during breastfeeding
If symptoms do not improve or if you feel very ill, you should contact a healthcare provider.
Can heat or cold help with a blocked milk duct?
Many find that both heat and cold can be soothing for a blocked milk duct, depending on when they are used. Tip: Plume Breast Warmers
Heat before breastfeeding or pumping can help the milk flow more easily and make it simpler to empty the breast. A warm shower or a warm compress are common tricks that many use.
Cold after breastfeeding can feel soothing if the breast feels swollen, tender, or hot. Cold can also provide a pleasant sensation when the breast feels tight.
When should you seek medical care?
Contact healthcare if:
- You have a high fever
- You feel very ill
- Symptoms do not improve within one to two days
- The pain worsens
- The redness is spreading
In some cases, treatment may be needed.
