Sybil has a lump in the general spot we gave her CDT about 8 months ago. I have to admit that I haven't had my hands on her that much lately because of life being nuts. She did have a knot after her CDT but I was sure it had gone away. Today, when I was trimming her hoofs I gave her a good look over and I found this (pic below) looks like it's white-ish, it's hairless and fairly hard and moves with her skin. What do y'all think?
