What is leaking from my breast? (Photo)

The fact that your right breast is hard swollen and painful combined with the leaking fluid indicates that you have a seroma.  The redness means the seroma is most likely infected.  This needs to be drained immediately, and the implant might need to be removed.

Call your surgeon and try to get in to see him or her as soon as possible. It could be something as simple as a stitch, but you don't want to run the risk of an infection so it's best that you get this checked out.
