Medical advice?

Hey all i need some insight at whats going on with my 1420 gram male butter pastel.

He seems to have sores or scabs on his lower jaw (left side) and a less pronounced mark on his right side. Also they seem to be occuring also on three of his pits.

What is this? He hasnt fed since 2/9/15 and hasnt consistently eaten since 12/28/14. I always fed live. Paper towel sub. Good humidity and decent temps. No hot spikes or tub ever below 75. Homemade rack other 4 snakes have no issues at all eat every time unless in deep blue. He is currently at the bottom of the rack.

Also he has always been a picky eater (mouser) and was kept in a 40gal breeder before i built the rack. It had much less heat and humidity. Ever since i put him in the rack hes been even more difficult to feed. So im worried this isnt just rubbing sores and its effecting his diet.

I will be going to a vet regardless. But would seriously appreciate any knowledge on this.

The two brown spots are the effected areas from his left side. Iphone pics suck.
