I don't have one. Only photos of the wound after stitches were removed. But I was told it was very large and also tested and found to have a large infection.
I dunno. I just know i set my eyes on the open wound for the first time today and almost crapped my pants. You could fit a tennis ball in my back. It was a shocker.
I had a cyst removed back in the day. It was nowhere near as large as yours. I was told if they just drained it and didn't also remove the sack it was in, it would come back.
