But it's most common during the first 6 months of breastfeeding (sometimes called chestfeeding). It is especially common during the baby's first 2 months. After 2 months, the baby's feeding patterns become more regular, which helps prevent mastitis. 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. 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. If you have mastitis, you may first notice: Signs that mastitis is getting worse include swollen and painful lymph nodes in the armpit next to the infected breast, a fast heart rate, and flu-like symptoms that get worse. Mastitis can lead to a breast abscess, which feels like a hard, painful lump. The symptoms of mastitis most often appear within 4 to 6 weeks after childbirth. Your doctor or midwife can usually diagnose mastitis based on your symptoms and by checking your affected breast. Tests usually aren't needed. Treatment for mastitis includes regular breastfeeding and self-care. If you have an infection, you will likely need antibiotics. Self-care includes taking ibuprofen (Advil, Motrin) and using cold compresses for discomfort and swelling. Treating mastitis right away with self-care can help keep it from getting worse and usually eases symptoms. Taking these steps can help prevent mastitis. If you have mastitis, you may first notice: These first symptoms may start after you have reopened a blocked milk duct. Signs that mastitis is getting worse include swollen and painful lymph nodes in the armpit next to the infected breast, a fast heart rate, and flu-like symptoms that get worse. The symptoms of mastitis most often appear within 4 to 6 weeks after childbirth. In some cases, symptoms of mastitis get worse and the breast forms a pocket of pus (abscess) in the infected area. Symptoms of a breast abscess include a breast lump that is hard and painful. The area may be reddish, purplish, or brownish, depending on your usual skin color. You may also have flu-like symptoms that are getting worse. 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. 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. Mastitis may go away with early self-care and management of symptoms. Sometimes you will need antibiotics. Treating it right away helps keep it from quickly getting worse and usually eases symptoms after about 2 days. Delaying treatment can lead to an abscess, which can be harder to treat. Treatment may include: You can safely keep breastfeeding your baby during illness and treatment. Your breast milk is safe for your baby to drink. Any bacteria in your milk will be destroyed by the baby's digestive juices. Treatment for a breast abscess includes: Most people can keep breastfeeding with the affected breast while an abscess heals. With your doctor's or midwife's approval, you can cover the abscess area with a light gauze dressing while you breastfeed. If you are told to stop breastfeeding from the affected breast while an abscess heals, you can keep breastfeeding from the healthy breast. Be sure to pump or express milk from the infected breast regularly. If you have trouble breastfeeding, talk to your doctor or midwife or a lactation consultant. Regular breastfeeding is an important part of caring for yourself when you have mastitis. If you have any problems with breastfeeding, talk to your doctor or midwife or a lactation consultant.
