So I have this bump

On my finger at the top where you bend and I’m wondering why I think it could be a cyst but idk I forgot to ask my doctor but now I’m worried about it the ppl on here will try to jump and say it’s a wart , but I don’t have hpv I had my gyno swob me down there and I’ve had a Pap smear in 2018 I’ve also had a hpv prevention shot in the past so I don’t wanna be negative and think that anyone else have the same problem.
