I have a 21 month old baby,never breastfed... one of my breast is sore and leaking milk... what is wrong?

Hi synceremommy,

Most likely there is nothing wrong. Even without breastfeeding, some women will experience leaking of breastmilk months later... at times it can be a few years later as well. It may have to do with when you ovulate as well.

Is there any chance that you might be pregnant again? That would be another possible reason. Sometimes it can also be due to a high level of prolactin. If it continues, and is frequent, you might have your doctor do some testing.
