The photos are coming out very blurry and grainy on my phone, so I'll let someone else touch upon that, but a few critical points:
He looks pretty dehydrated in the photo. What is your humidity level at?
What is the UVB output, style, and brand of bulb?
-you should have 5.0 or 10.0 UVB output; T8 or T5 bulbs are better than coiled (spiral) bulbs; ReptiSun is better than ReptiGlo
How old is the bulb?
-they need to be replaced every 6 months. Even if they light up, they're not emitting UVB.
What are you gutloading feeders with?
-the dry powder and jelly cubes they sell at pet stores are useless; if you're not gutloading properly, it's just like feeding them junk food (no nutrients)
You need plain calcium with no phosphors or D3 every feeding.
-not enough calcium will cause the degenerative, MBD.
D3 should only be given twice a month or so.
- too much will cause health problems with symptoms that mirror MBD.
MBD is degenerative
-it gets worse over time; there is no cure: all you can do is stop it from progressing. It will eventually get bad enough to the point of death.
