What the heck happened to my trigger?

The area does not look raised really, other than the flaking skin (or what looks like skin). It doesn't look bumpy really, just more flaky and the discolored area isn't bumpy. It might be an infection caused from a wound, 4 or 5 days ago, we noticed that it had a little scrape in it's nose, so we night be getting somewhere here.

As for food...what haven't we tried. So far, we have tried frozen mysis, krill, and brine shrimp. Also, we have tried clams on a half shell, formula 2 flake, nori and cyclopeeze. We have been soaking the frozen food in garlic as well. I have been dosing the tank with Vitamin C too to try and give the fish a boost. I'm kinda at my wits end with this fish, something should be appealing to eat by now you'd think.
I will try to get better pics when I get home but the location of the tank that it's in, makes it awkward to get a good shot. I also have 2 different threads going on RC right now, but no one on there seems to be much help yet.
