I know its not a kink only because its just on the skin (kinda like a hard zit) and i got him because A:i had a friend who is a breeder check him out at the show when i got him and he said it was no big deal and B: for $350 i couldn't pass it up (knowing that it wasnt a life threatening problem) i guess i should just bring him to the vet and have them "pop" it or remove it somehow
