Most mastitis advice is out of date

In 2022 the Academy of Breastfeeding Medicine (the Academy) rewrote its mastitis guidance, and the change was substantial (ABM Clinical Protocol #36). The old picture was a plugged duct cleared by force: pump the breast empty, massage hard, apply heat, soak, repeat. We now understand that those specific steps often push the problem in the wrong direction.

Here is what changed and why it matters. Mastitis is now understood as a spectrum of conditions rather than a single condition. The breast regulates its own supply through feedback, so removing milk more often, by extra pumping or feeding only on the sore side, signals the body to make even more milk and worsens any already present congestion; furthermore, this extra milk removal may cause congestion where there wasn't any to begin with. Forceful or deep massage injures already inflamed tissue and increases swelling, and per the protocol it is a recognized risk factor for more serious problems like phlegmon and abscess. Applying heat to the breast(s) between feeds increases inflammation, too. In contrast, the current approach is, in a real sense, to do less and to do it gently: apply ice or a cold compress to bring down swelling and calm the inflammation, keep milk moving gently and only to comfort, consider anti-inflammatory medications, and reserve antibiotics for true bacterial infection.

This is why following the outdated playbook can turn a manageable inflammation into a worse one. A large part of what we do is stop the harm and reset the plan around what actually helps. For selected cases we may offer therapeutic breast ultrasound (TUS) in the office. The protocol includes TUS as an option for treatment of the mastitis spectrum, when used appropriately and discussed honestly with each patient.

Mastitis is a spectrum of conditions, not one thing

The conditions below often overlap with each other, and the same parent can experience features of more than just one of them. We do not try to pin people to a spot on a line. Our skilled providers take a history, do a thorough exam, and then make an assessment and recommendations based on what they find. That is the real process, and it is what determines the right treatment.

• Hyperlactation, or oversupply. Making more milk than the baby removes or needs is a common starting point and a frequent driver of recurrent mastitis (ABM Clinical Protocol #36). When it is present, addressing it safely is often the key to breaking the cycle. Many parents have oversupply without realizing it, and many do not have it at all, which is why we assess rather than assume.
• Ductal narrowing, formerly called a plugged or clogged duct. Inflammation and swelling around a duct narrow it and slow milk flow, producing a focal tender area of firmness, sometimes with mild redness and usually without feeling sick. The protocol is clear that the breast's ducts are innumerable and interlacing, and that there is no literal macroscopic plug to dig out, which is exactly why squeezing or forceful massage causes tissue trauma instead of relief (ABM Clinical Protocol #36, p.363).
• Inflammatory mastitis. A specific region of the breast becomes increasingly red, swollen, hot, and painful, and there may be fever and chills. The protocol notes that this is inflammation and that the body can mount a strong systemic response even when there is no infection, so a red, painful breast does not automatically mean antibiotics are needed (ABM Clinical Protocol #36, p.363).
• Bacterial mastitis. When inflammation progresses to true bacterial infection, or does not improve with conservative care, antibiotics may be appropriate. Telling bacterial mastitis apart from inflammation is a clinical judgment based on history and exam, including whether systemic symptoms persist and whether the breast is responding to conservative measures (ABM Clinical Protocol #36, pp.363-364).
• Subacute mastitis. The Academy defines this as narrowing of the ducts by bacterial biofilms in the setting of chronic mammary dysbiosis, which is a disruption of the breast's normal microbiome (ABM Clinical Protocol #36, p.365). The bacteria involved do not produce the toxins that drive acute infection, so systemic symptoms are uncommon and the breast symptoms are milder and more lingering: deep, burning, or needle-like pain, recurring nipple blebs, and recurrent areas of firmness or congestion. This is the condition most often mislabeled as a yeast or thrush problem. The protocol states plainly that there is no scientific evidence that yeast causes this kind of persistent nipple and breast pain, so we treat it as what it actually is (ABM Clinical Protocol #36, p.363).
• Phlegmon. When inflammation consolidates into a firm, mass-like area without a drainable pocket of fluid, it is called a phlegmon. The protocol calls for anti-inflammatory care and, when indicated, a course of antibiotics, along with close follow-up. Sometimes imaging is needed to confirm it is settling rather than forming an abscess. Breastfeed Atlanta manages phlegmon conservatively in the office and coordinates the imaging when necessary (ABM Clinical Protocol #36, pp.364, 372).
• Abscess. If a phlegmon or a bacterial infection progresses to a walled-off pocket of infected fluid, that is an abscess, and the care changes. When an abscess is suspected, or cannot be ruled out, we refer promptly to our local network of breast specialists and surgeons, and we provide the feeding support around that care so milk supply and breastfeeding are protected throughout (ABM Clinical Protocol #36, pp.364, 373).
• Galactocele. A galactocele is a milk-filled cyst that can form when ductal narrowing blocks the flow of milk. It is a distinct condition, not an abscess, and is usually felt as a smooth, moveable lump that may change in size around feeds. We evaluate it and coordinate imaging if needed; when a galactocele requires more intervention, that is handled by the right specialist (ABM Clinical Protocol #36, pp.365, 373).
• Related conditions we also manage. A milk bleb, a small blister at a nipple pore that can cause a pinpoint of sharp pain, sits alongside this same picture and is managed on its own terms.

What clinical evaluation looks like at Breastfeed Atlanta

When a patient comes in for mastitis or a painful breast, here is what to expect.

• A focused history. We go through the patient's symptoms and their timeline, the feeding and pumping pattern, any prior episodes, and how it has been treated so far. We listen carefully, because the history often reveals both the likely cause and the well-meaning steps that may be making it worse.
• A thorough exam. We take a full set of vitals and examine the breast and skin, checking for a bleb and for signs that point toward bacterial infection or toward anything that may need imaging. When it is helpful, we examine other body systems as well, and sometimes we examine the baby, since what is happening with the baby's feeding can explain what is happening in the breast.
• A view of milk supply and removal. Because hyperlactation so often drives mastitis, we look closely at supply and at how milk is being removed. This may involve observing a pumping session, hand expression, or a breastfeed during the visit, and we address what we find directly.
• An assessment. Putting the history, exam, and feeding picture together, we form an assessment and share it openly. This is a shared decision with the family: we review what we are seeing, weigh the options, and balance evidence-based treatment against the family's own needs, values, and goals.
• A clear written plan. Every visit ends with a written plan the patient can follow: what to do, what to avoid, what to watch for, and when to follow up. The plan reflects a clear treatment decision, whether to treat the problem as inflammation or, when bacteria are driving it, to add antibiotics, rather than reaching for antibiotics for every red breast, since infection is itself an inflammatory state. Coordination is part of every plan, not only the complicated ones. We are always in contact with the patient's primary care provider, whether that is an OB, midwife, or internal medicine physician, and we bring in other specialists, such as endocrinology or breast surgery, when the situation calls for it.

What we treat directly and what we coordinate

Families deserve transparency, so we are clear about what we treat ourselves and what we coordinate with other providers.

What we address directly

• The evidence-based anti-inflammatory plan. Nearly all mastitis begins as inflammation rather than infection, which is where care starts. We build the core plan the current protocol calls for: cold therapy to reduce swelling, guidance on anti-inflammatory and pain medication, gentle lymphatic drainage rather than deep massage, rest, and feeding to comfort rather than pumping the breast empty. We also coach patients away from the common steps that worsen inflammation (ABM Clinical Protocol #36, p.369).
• Addressing hyperlactation. When oversupply is driving recurrent episodes, we work on lowering milk supply gradually and safely, with frequent check-ins so the mother's own needs and comfort stay balanced with safety. Some people prefer to keep a degree of oversupply, and that is part of the conversation, since the goal is the supply that works for each family, not a single target (ABM Clinical Protocol #36, p.369).
• Prescribing antibiotics when warranted. When the exam points to bacterial mastitis, our collaborative team of IBCLCs and nurse practitioners, some of whom are the same person, can prescribe an appropriate antibiotic, such as dicloxacillin or cephalexin per the protocol, and coordinate with the patient's other providers. Our team practices antibiotic stewardship as part of a holistic approach, so we hold off when the problem is inflammation rather than infection, since unnecessary antibiotics disrupt the breast microbiome (ABM Clinical Protocol #36, p.372).
• Therapeutic breast ultrasound. For selected cases, such as recurrent ductal narrowing or persistent inflammation, we offer in-office therapeutic ultrasound, which uses gentle thermal energy to help reduce swelling and ease the affected area. The protocol includes it as an option within the mastitis spectrum and the evidence is still developing, so we offer it as one tool within a broader plan rather than a guaranteed fix, and we are honest with patients about that (ABM Clinical Protocol #36, p.370).
• Bleb and recurrent-issue management. We manage nipple blebs conservatively and build prevention plans to keep parents from landing back in the same place. Many people come to us after seeing other providers without getting the issue resolved, and a large part of our work is finding the driver that was missed (ABM Clinical Protocol #36, p.369).

How we coordinate and refer

• Our referral process. Coordination usually starts with a referral. We look for a provider in the patient's insurance network and close to home, confirm they can be seen without a long wait, hand off directly so the new provider knows the patient is coming, and send full records. We then schedule a follow-up so the patient is never left to manage the transition alone.
• Management of an abscess. When an abscess needs treatment, that care is provided by the right specialist. We coordinate it promptly and provide the feeding support around it.
• Imaging and further workup. If a lump or area of redness does not resolve as expected, it needs evaluation to make sure nothing else is going on, and we make sure that happens with the right provider rather than letting it linger.

When to come in

We know these situations are urgent. When a mother or lactating parent is in pain and a baby still needs to feed, waiting is hard, and we treat that urgency as real.

Call us at (404) 454-9715 to talk it through. If symptoms are escalating quickly or include feeling very unwell, treat it as urgent.

Insurance and billing

Most commercial insurance plans cover lactation visits, often at minimal out-of-pocket cost depending on health coverage. Breastfeed Atlanta is in network with Aetna, Anthem Blue Cross Blue Shield, Cigna, UnitedHealthcare, UMR, Humana, and Ambetter. We are also in network with every Georgia Medicaid CMO, including Amerigroup, CareSource, Peach State, and Molina.

Our billing team is in house. We verify benefits before the first visit so patients know what to expect, and we work directly with insurers. If a plan is unclear, we will check it in advance.

What to expect from a visit

A visit includes a focused history, a thorough exam, a view of milk supply and removal, a shared assessment, and a clear written plan. We do not rush.

After the visit, a clinical note goes to the patient's pediatrician and OB so the full care team stays informed, and we set a follow-up based on the patient's response.

Frequently asked questions

Why Breastfeed Atlanta for mastitis

We are a multi-specialty lactation practice serving mothers, lactating parents, and families across metro Atlanta, with a collaborative team of IBCLCs and nurse practitioners, some of whom are the same person, supported by clinical oversight from a board-certified lactation medicine physician (NABBLM-C).

We are committed to staying current with the evidence and bringing it directly to the bedside, so the care reflects what actually works today. We take a history, examine the patient, treat the inflammation the way the current evidence supports, prescribe antibiotics judiciously and with appropriate stewardship, offer in-office therapeutic options, and coordinate imaging or specialist care when something more serious is developing. That depth of care is the difference between guessing and getting better.
