Thanks for using Petco Pet Education Center, formerly Petcoach! This is not likely to be due to the vaccine or due to the vet hurting him. This is more likely due to some form of mild trauma perhaps when playing. I would just continue to monitor him for now. If this does not go away on its own in the next 72 hours or it worsens, have him evaluated by a veterinarian for further assessment and treatment. Good luck and have a good night!
