Growth on Tail?

[Birdey]

Hi
So I’ve been to two different vets (exotic) and both said pretty much the same thing, just kind of looked at it and said they’ve seen things like this on other BDs and it’s just a little growth, bla bla bla. But the growth has changed since then, it has grown in seize and is pinkish. I’m coming here for information on it, hopefully. Her name is Liz. It feels like it’s growing around the tail and where it first began has been growing longer, okay, it’s expanding and getting bigger, pretty much. It grows very slowly but it’s definitely getting larger. She’s had for quite a while, probably 2-3 years now. And it does seem to hurt her, if I press on it she pulls her tail away, but if I press on a different part of her tail she doesn’t.
Liz is very much alert, eating, happy, and going potty no problem.
Thank you!

I honestly don’t know, but with the light to it looks like maybe a fluid filled cyst. I’m not a doctor and haven’t seen anything like that before. Search for a local Herpetological society and see if they can advise since your doctors are seemingly not knowing.

I would go back to the vet and explain that it has gotten bigger since they saw her and that it's painful. I can't believe they would blow it off if you say she's in pain.
