[Moved here from Behavior because this looks quite serious]
Oh my goodness, that's isn't normal.How long has he been doing that? Has he had a fall perhaps? How long have you had him? His eyes really don't look good either and he is very thin. Is he active or does he spend a lot of time in that position? Is he able to climb at all?
He's active and climbs all over his setup
To help rule things out, could you give us a rundown of your setup?
What brand & type of UVB are using? Is it a coil, compact, fluorescent tube or mercury vapor bulb? What distance is this particular bulb?
I'm using a repti-glo 10.0 for UVB
Basking light is this bulb

Distances are about 7-8 " to his highest point.
What are the tank temps, what type of thermometer are you using and where exactly are you checking them?
Temps range 105-85 on the warm side and go down to about 75-80 on the cooler side. I use a Milwaukee laser temp gun along with digital thermometers in the setup.
Also, what feeders are you using, how many times a day are you offering them and how many is he eating daily? What greens/veggies are you offering and is he eating any?
He eats about 12-18 crickets daily, he doesn't really touch veggies to much but I have seen him testing them with his tongue. I was told this was normal and eventually he will eat more veggies and fruits as he gets older.
How often do you dust the feeders with calcium & vitamins?
Dust crickets about every 3rd day with calcuim, no vitamins.
Have you been
bathing him? If so, how often?
About once a week
Please answer these questions as soon as you can so that we can try to figure out what is going on.
