Plugged Ducts and Mastitis
How to tell the difference and what to do about each
Plugged Duct vs. Mastitis
A plugged duct feels like a tender lump in one breast with no fever. The skin over the lump may be slightly red but you feel otherwise fine. Mastitis is different: the same tender area plus a fever over 101 degrees Fahrenheit, chills, body aches, and a feeling of having the flu. If you think you have the flu and you are breastfeeding, you probably have mastitis. Do not stop nursing on the affected side. Continuing to empty the breast is the most important treatment for both conditions.
Treating a Plugged Duct
Start treatment at the first sign of a lump. Apply warm compresses or take a warm shower before feeding. Massage the lump gently toward the nipple while the baby nurses. Position the baby with their chin pointing toward the plugged area, as this directs their strongest suction to the right spot. Vary nursing positions with each feeding. Rest as much as you can. If the lump does not resolve within 24 to 48 hours or you develop a fever, call your provider.
Treating Mastitis
Mastitis requires the same measures as a plugged duct plus additional steps. Rest in bed. Continue nursing frequently on the affected side, starting each feeding on that side. Drink plenty of fluids. Take ibuprofen to reduce fever and inflammation. If symptoms do not improve within 12 to 24 hours of these measures, you may need antibiotics. Call your provider if your temperature stays above 101 or you feel worse.
