- Un blocked milk duct: the breast has not been emptied sufficiently, there has been a long time without breastfeeding or emptying, or there is pressure on the breast (tight clothing, sleeping face down, pressure from the baby while breastfeeding, etc.).
- Bacteria that penetrate through cracks in the nipple due to poor baby positioning or injuries.
Before you continue reading, an important clarification: Mastitis is not dangerous for the baby and, in most cases, You should not stop breastfeeding.In fact, continuing to breastfeed helps drain the breast and promotes healing. The vast majority of The indicated antibiotics are compatible with breastfeeding.If you are prescribed any medication, check its compatibility and follow professional advice.

Mastitis symptoms

Los mastitis symptoms most common are:
- Localized sensitivity in an area of the breast, sometimes with lump due to accumulated milk.
- Heat and redness in a sector (often wedge-shaped).
- Swelling and pain, sometimes with a burning sensation, especially during intake.
- Fever, chills, general discomfort similar to the flu, Fatigue and nausea.
If you present deep breast pain that does not improve with adjustments to latch and breastfeeding technique, or persists without external signs, may be ductal infection or subacute mastitis, which requires professional assessment.
Diagnosis and tests
El Diagnosis is usually clinical. through examination and background checks. In selected cases, your professional may request a breast ultrasound to discard abscess or confirm the location of the collection.
El milk culture It's not routine, but it's recommended if there is sluggish evolutionrecurrent mastitis, suspected SARM (methicillin-resistant Staphylococcus aureus) or if there is no improvement after 24–48 hours of appropriate empirical treatment. The sample is preferably obtained before starting antibioticswith hygiene of the area, by manual extraction and in sterile containers.
If symptoms do not improve after completing the antibiotic or if there are atypical signs, your doctor may recommend mammographyrepeat ultrasound or even biopsy to rule out other pathologies such as inflammatory breast cancerwhich can mimic mastitis.

Mastitis treatment
Mastitis requires medical attention.Management combines general measures and, where appropriate, antibiotics compatible with breastfeedingContinuing to breastfeed is usually safe and recommended.
General measures:
- Lactation on demand without letting the breast become overfilled; offer the affected side first if you can tolerate it.
- Adjusting the grip and position to improve drainage. Place the baby's chin Focus on the affected area. Seek support from a midwife or lactation consultant.
- gentle heat (warm cloth) just before feeding to encourage the ejection reflex and cold between doses to relieve pain and inflammation.
- Anti-inflammatory analgesia safe (ibuprofen or paracetamol) according to professional guidelines.
- Rest and hydrationShe asks for help with housework and baby care.
Very important: avoid the intense compression or vigorous massage of the chest, which can worsen inflammation. If you perform massage, to be smooth and superficialfrom the affected area towards the nipple and only to help the milk flow.
Milk extraction depending on your situation:
- If you are breastfeeding directly, offer both breasts at each feeding and avoid "over-emptying" after the baby has finished. Extracting much more volume than needed can perpetuate inflammation by overproduction.
- If you are exclusively expressing breast milk, adjust the suction of the breast pump to a comfortable level and extracts approximately the volume that your baby takesDo not force prolonged sessions.
- If you combine breastfeeding and formula feeding, breastfeed whenever your baby is hungry, and if one feeding is with a bottle, express milk. similar amount which is offered to the baby.

If mastitis does not improve with these measures, or if you experience high fever and severe pain, your doctor may prescribe [medication/treatment]. antibioticsUsual regimens (the choice depends on history, allergies and local prevalence of resistance):
- front line no suspicion of MRSA: cloxacillin 500 mg every 6 hours for 10-14 days (or dicloxacillin/flucloxacillin depending on availability) or cephalexin 500 mg every 6 hours for 10-14 days; it is also used cefadroxil 1 g every 12-24 h for 10-14 days.
- Beta-lactam allergy: clindamycin 300-450 mg every 8-12 h for 10-14 days.
- Suspected/confirmed MRSA: trimethoprim-sulfamethoxazole 160/800 mg every 12 hours for 7-10 days or clindamycin (depending on sensitivity). Avoid TMP-SMX if your baby is prematureHas jaundice, G6PD deficiency or less than 1-2 months.
Some guidelines are resolved in 5-7 days if the improvement is rapid; however, many guidelines recommend 10-14 days to reduce relapses. Take the complete cycle unless otherwise indicated.
Less useful drugs such as Amoxicillin clavulanic They are not usually the first choice for uncomplicated mastitis; quinolones They are avoided due to their ecological impact. In severe cases (sepsis, rapid progression) they may be required hospital admission and intravenous antibiotic.

If mastitis progresses, a tumor may form. abscess (accumulation of pus). It manifests as fluctuating massPain, swelling, and fever. Ultrasound helps confirm size and location.
El treatment of choice is the needle aspiration drainage (preferably ultrasound-guided), sometimes after several punctures. In large or multiloculated abscesses, further procedures may be required. incision and drainageA sample is taken for culture and added antibiotics (oral or IV depending on severity). Ideally continue breastfeedingpreventing the baby from coming into contact with the drained material.
MRSA risk and antibiotic choice
Some factors increase the risk of MRSA infectionRecent hospitalization, invasive procedures, prolonged antibiotic treatment, living in crowded or unsanitary conditions, or community-acquired infections in high-prevalence settings are risk factors. If MRSA is suspected or there is no improvement after 48 hours of treatment, the doctor may change the antibiotic and request culture.
Breastfeeding, medication, and baby safety
The milk of a mother with mastitis is still safe for babyThe taste may change slightly, and the baby might temporarily refuse that breast; if this happens, extract the milk to maintain milk production and offer it in a bottle.
