Causes of Clogged Milk Ducts

Many factors can increase your risk of developing mastitis, such as:

Cluster Feeding Schedule in Newborns

If you suspect you may have mastitis, contact your healthcare professional to schedule an appointment. During your meeting, they’ll ask you about your symptoms and examine your breasts in order to come up with a diagnosis.

In some cases, such as recurrent mastitis, you may need additional tests like a breast milk culture, which can be taken with a small breast milk sample from your affected side.

With this and other tests, your healthcare provider can determine the exact cause of your infection to ensure you’re given the best antibiotics to treat it or rule out other conditions that may cause similar symptoms.

To treat mastitis, your healthcare provider may prescribe an antibiotic that’s safe to take while breastfeeding, such as dicloxacillin, cephalexin, clindamycin, or erythromycin. You’ll also need to empty your breast regularly.

Inflammatory breast cancer, a rare type of breast cancer that spreads rapidly, can cause symptoms that resemble mastitis such as breast swelling, purple or red skin, and an orange peel-like dimpling of the skin.If antibiotic treatment does not help your mastitis clear within a week or so, don’t delay. Contact your healthcare provider to schedule another exam to ensure it’s not cancer and to avoid a worsening infection.

It’s totally understandable if all you want to do isstopbreastfeeding when you’re feeling run down and your breast hurts. Mastitis can be life-disrupting during an already challenging time, and many people say it makes it difficult to get through day-to-day tasks, let alone breastfeed.

In the meantime, here’s how to cope:

A Word From Verywell

Mastitis is likely the last thing you want to deal with when you’re getting to know your new child and recovering during the postpartum period. But sometimes it can serve as a signal that it’s time to prioritize rest and self-care or lean on the expertise of a nurse or lactation consultant.

Remember that you’re not alone; there are people who can help. This condition is highly treatable with the right medication and coping skills.
