Pus from nipple after Mastopexy/Aug May 25 2015? (Photos)

I'm just over 7 weeks post op and everything has gone smooth aside from the internal sutures that keep spitting out. Just over a week ago I had a bunch of the spitting sutures takes out and tonight I was looking to see of there wear any more and there was a piece of skin the size of my pinky nail lifted up so I lifted it off as it just peeled right off painlessly, but the skin underneath it was wet shinny so I grabbed my breast to pull it closer to my face to get a better look and pus oozed out
