You might be hearing conflicting advice for treating clogged ducts or mastitis. You might even be hearing the phrase “new protocol/protocol 38” but what is this new protocol for mastitis, and how does it apply to pumping mommas?

First of all, what in the world is this creepy image. anyway? For those of you who are old enough, or have parents that like to frighten you around the holidays, you might recognize “HeatMiser” and “SnowMiser” from “The Year Without Santa Claus.” (Weird movie, do not recommend) It’s the first image I thought of when I opened up my laptop to write this post. The battle between heat and cold…. that’s what’s been going on for mastitis treatment. Should you apply heat, vibration, and massage? Or should you ice it and take medication? It’s truly been a battle of heat vs. cold.
The old advice: HEAT
The solution was once to use heat packs, vigorous massage, and vibration to treat clogged ducts and mastitis. This is no longer recommended. We now know that a “clogged” duct is not a solid piece of milk we must shove through. What is really happening, is that the duct has become inflamed and has narrowed, not allowing as much milk through. With the knowledge we have regarding inflammation, we know that HEAT and massage may make inflammation worse, not better.

The new advice: COLD
So how do we treat an inflamed milk duct? With ice and ibuprofen! Applying COLD to the breast can reduce inflammation, allowing milk to flow freely from the duct. Taking a nonsteroidal anti-inflammatory drug (abbreviated as NSAID) like ibuprofen may also help. (Tylenol/acetaminophen is NOT an NSAID, so opt for Advil/ibuprofen instead.) An ice pack designed for the breast, like this one by Lansinoh, or this multi-pack which can be used of little kid boo-boos long after breastfeeding!. You can also use a frozen bag of peas, which flexes nicely around the breast. Light, lymphatic massage may also be helpful, but refrain from applying vibration/vigorous massage to the affected area. And because I know you will ask… Yes, you can still feed baby your milk when you’re taking an NSAID anti-inflammatory medication or an antibiotic.
How do you know if you have mastitis?
The updated 2022 Protocol #36 guidelines from the Academy of Breastfeeding Medicine (ABM) published in May 2022 now assert that mastitis should be considered “a spectrum of conditions”, ranging from oversupply (hyperlactation) to inflammation, bacterial infection and abscess. LactApp covers it pretty succinctly in their post HERE . Mastitis can be:
- Ductile narrowing/inflammation
- Inflammatory mastitis (what we think of as unresolved “clogged ducts”)
- Bacterial mastitis caused by Staphylococcus and Streptococcus
- Phlegmon- suspected when mastitis worsens as a firm, mass without fluctuance
- Abscess: An accumulation of infected fluid that needs to be drained
- Infected galactocele- a significant volume of obstructed milk accumulates in a cyst-like cavity
… in easy-to-understand terms, please?
Contact your doctor if you are experiencing:
- Prolonged unresolved clogs, or hard areas of the breast that don’t seem to be emptying when you nurse or pump
- Redness of the breast (With darker pigmented skin, this may appear darker or a reddish-brown hue)
- Burning sensation in the breast
- Areas of the breast that are painful or warm to the touch
- Any of these symptoms accompanied by fever and flu-like symptoms

Why has my milk supply gone down?
It’s normal to see a reduction in milk supply after a prolonged clogged duct or mastitis. Why? It’s actually your body trying to protect you! If milk has not be adequately emptied from one breast, it causes internal pressure inside the milk-making cells of that breast. This sends signals to your body to slow down production in that breast. These protective signals result in less milk being produced. For some mommas, this drop in supply is temporary. When the milk starts flowing again, the body often sends the message- “okay! milk is being removed, make more!” But sometimes that breast will remain at a lower output. This is why dealing with “clogs” as soon as possible is so important!

Implications for exclusive pumpers
The initial advice “not to pump” following the new protocol has confused exclusive pumpers (mommas who pump exclusively and do not latch baby at the breast). The protocol advises you to nurse on demand and not excessively pump. So, for exclusive pumpers, YES you’ll need to pump. I advise you to pump as you would normally pump- not longer or more often. Excessive pumping can lead to an upregulation of milk and a continued cycle of mastitis. Many mommas find that switching to a manual pump gives you more control and can help finesse the clog out. My advice regarding “clogged ducts” tailored for exclusive pumpers can be found HERE.

The short version:
In summary… The ABM protocol change in 2022 gave us a lot of think about, and in many ways, completely changes the way we treat clogs and mastitis. What we used to think of as a “clogged duct” is actually ductile narrowing brought on my inflammation. Mastitis is a spectrum of conditions in the breast, from inflammation which can be treated at home with ice and ibuprofen, to infection, which needs medical attention. Avoid intense massage and vibration. Choose a cold compress over a hot one. Nursing mothers should keep feeding on demand without adding additional pumping sessions. Exclusive pumpers are encouraged to stick to your pumping schedule as much as possible. Manual pumping or hand-expression is an excellent alternative in both cases.
