I have my horse-vet's email addy, I've sent him pics before when I've had questions, but I don't have email for the small animal vet.
I've seen something sortof like this before when Logan was neutered. He was 8 when I neutered him. I took him home, and the next day he was hurting bad. Rolled him over and his testicles were BACK! poor guy, the sacks were all full of blood. But I had to laugh when I called the clinic and said "They're baaaaaaack!"
Maybe call her back and ask her if she would like to see?
