breast leaking and I'm not pregnant tmi pics

Sabrina

my right breast has hard lump. I haven't breast feed in 2 and 1/2years. it's been there going on 3 weeks I'm going to the dr on the 26th. it's a greenish yellow discharge and the other 2 pics show how wide and long it is. it's located near my nipple so I hide it in the photos.
