Mastitis is an inflammation of the breast tissue. Infections may or may not occur with mastitis. It often affects women who are breastfeeding.
Mastitis may occur because of sore or cracked nipples, latch problems, plugged ducts, oversupply, yeast infections, or milk not draining well.
These are the most common symptoms of mastitis:
Hot, swollen breasts
A red, painful, or hot "wedge-shaped" swelling on a breast, or both breasts
A red, painful, or hot lump in your breast
Red streaks on your breasts
Fever of 100.4°F (38°C) or higher, or as directed by your healthcare provider
If you have these symptoms, contact your healthcare provider as soon as possible. You may need treatment for mastitis.
Your healthcare provider will examine your breasts. In most cases, you won’t need lab tests. But you may need the following tests:
Breastmilk culture. This may be done if an infection is severe, occurred in the hospital, or hasn’t responded to a previous course of antibiotic treatment. This can be used to guide the choice of antibiotics.
Ultrasound. You may need this imaging test if the mastitis is linked to breastfeeding and doesn’t get better with treatment in 48 to 72 hours.
Blood cultures. These will be done if the breast redness keeps growing or your vital signs become unstable.
Mastitis treatment includes draining the breast, applying heat, getting rest and plenty of fluids, and taking pain medicine. Antibiotics may be prescribed.
It’s very important to keep the affected breast "empty" through frequent breastfeeding or pumping sessions.
It may be too painful to have your baby nurse on the infected breast. Move your baby to the other breast, open both sides of your bra, and let the milk flow from your sore breast onto a towel. Milk from the infected breast can also be removed by a breast pump. You can feed your baby the expressed breastmilk if they accept it.
Massage the area. Start at the sore spot and move your fingers in a circular motion and massage toward the nipple.
Put heat on the area with a warm, wet cloth.
Wear a well-fitting bra that is not tight. Sometimes a tight bra constricts milk ducts and causes problems.
Ask others to help so you can get some extra rest and sleep. Breast infections are often a sign that you are doing too much and getting overtired.
If you think a latch problem may have helped cause your mastitis, think about seeing a certified lactation consultant.
It’s very important to rest and keep hydrated by drinking a lot of clear fluids.
You can take ibuprofen or acetaminophen for the fever or mild pain.
An antibiotic may be prescribed for 10 to 14 days. Take all of the medicine or the mastitis may come back. The antibiotics used for mastitis are generally safe to use while breastfeeding.
