Re: Wacky nipple hijinks!
It's quite possible that the fluid you saw was not pus, but rather extremely watery milk that had built up in a plugged duct behind a nipple blister. The white, puffy area with a pit in the middle- that's kind of how my most recent blister looked. (I am prone to them, particularly when my kids are teething.) I think the best way to figure out if this was milk or not is to (hold onto your socks!) taste it. If it tastes like very watery, possibly very salty milk, then I'm right and it's nothing to be overly concerned about. If not, then it could still be infection and you may need to see your doctor. Either way, the absolute best thing to do is to empty this stuff right out, since if it's pus you want to clear it out, and if it's milk you want to clear it out to prevent infection from setting in.
