HELP!! Buddys tail is a little bit kinky!!

[BeardedBuddy]

Hi all,
My little buddy has a hug kink in his tail from the lower part of his back down to the center of his tail, it kind of curves down..looks broken but its not!!!  He is still moving fine, eating like a horse and seems pretty content..... He eats crickets daily as well as mealies, fresh vegtables and has calcium intake. Lighting is fine as far as I know, he has a 50 watt basking light and a UV light the length of his tank, water daily etc
He does need to be moved to a bigger tank as he is getting a little big for his currant living quarters, but these kinks have been there for a while now? I am wondering if its a birth defect?? Any help would be appreciated...thanks in advance

I have a few questions that might help us to figure out what's going on. Please give us as much detail as you're able to.

How old is your dragon?
What is the temp of the basking surface directly under the heat light?
What kind of thermometer are you using to measure that temp?
What is the brand and rating of the UVB light? It should be stamped on the bulb.
How old is the UVB light?
How close to the UVB can the dragon get?
What is the substrate (floor covering) that you're using?
Does the dragon poop regularly?
Is it normal or does he strain when he poops?
Do you bathe him?
How often?
What is the brand of the calcium you're using?
How often do you give it to him?

Mealworms aren't a healthy choice for these guys. They're full of fat, chitin (hard to digest shell), and phosphorus (keeps the body from properly using calcium). There's very little meat to them, and almost no nutrition. They can contribute to serious health problems later on - fatty liver disease is a common one. Stick with crickets, feeder roaches, phoenix worms, silkworms, hornworms, or superworms.
