I have personally experienced thrush confined to only one duct that has always been a difficult one to drain even with breast compression and position rotation. I've also seen it in patients, so if it walks like a duck, quacks like a duck...treat it like a duck (with thrush). For many moms, the high levels of estrogen in pregnancy (with correspondingly high blood sugar levels) are enough to bring on low level yeast. Once baby is delivered and breastfeeding starts, the thrush is given a nice spot to grow on or in the breast. As the hormone levels drop and then normalize postpartum, plus not having constant leaking and moisture by 10 weeks, I suspect all of this contributed to her pain resolution in the past.
