Sorry if the title of this post is offensive, but that's really how I feel about it. Good riddance to those freakin' stitches.
I had my follow-up appointment today with the surgeon. He told me that the lump they pulled out of my armpit was called a Lactating Adenoma (it was, indeed, breast tissue after all). I looked up some articles about those things on the internet, and the more I read about this sort of weirdness, the more I realize I made the right decision to have it removed when I did. Check out this scary article about one of these things.
Now, I just need to get some things done for work, and this baby boy can show up anytime!
