Mastitis is a breast inflammation sometimes caused by infection. It can happen at any time. But it's most common during the first 6 months of breastfeeding (sometimes called chestfeeding).

Mastitis can be painful and make you very tired. But it is usually easily cleared up with self-care and sometimes antibiotics. You can continue to safely breastfeed your baby while you have mastitis. In fact, breastfeeding usually helps to clear up mastitis.
What causes it?
Mastitis can happen when the milk ducts narrow and do not drain properly. This can cause swelling and inflammation in the breast. And sometimes the tissue can become infected with bacteria. Infection is more likely to occur if you have cracked or sore nipples.

Information about Mastitis While Breastfeeding
Your doctor or midwife can usually diagnose mastitis based on your symptoms and by checking your affected breast. Tests usually aren't needed. But tests may be done to confirm a diagnosis. They may also be done to help guide treatment for other problems that can develop.
If you have an infection that isn't improving with treatment, your doctor or midwife may do a breast milk culture. To provide a sample for a culture, you will squeeze a small sample of milk from the affected breast onto a sterile swab. The culture results help your doctor or midwife confirm a diagnosis and find out the specific bacteria causing the infection.
Culture results may also be used to find out which antibiotic will work best for you.
Diagnosing a breast abscess
Your doctor or midwife can diagnose a breast abscess by checking your breast. If an abscess is deep, your doctor or midwife may use a breast ultrasound to check it. Ultrasound can also guide a needle to drain the abscess. A culture can then be done to identify the bacteria causing the abscess.
