Question: are clogged milk ducts normal?
Answer: A 2011 study of 117 breastfeeding women found that 4.5 percent experienced clogged ducts at some point during the first year of breastfeeding. A duct that remains clogged can cause mastitis, a painful infection in the breasts. Although a clogged milk duct can be painful, it is often treatable with home remedies.
