methicillin-resistant staphylococcus aureus infection
"I got a breast infection that was found to be mrsa.  I was admitted for IV antibiotics.  I was exclusively nursing a 6 week old.  I continued to nurse my newborn with the infection and on the medication.  My baby or I had no side effects.  (no yeast, digestive issues)  It cleared up my infection fast.  I got 3 days of IV and 7 more days of oral medication."
