Awe poor baby. Maybe it is just the pics but it looks like your cham has some gular edema?
You know, this poor little guy was one I posted about recently. I've only had him about two weeks. I ordered him from a breeder a pet store (which I frequent) suggested/uses. I bought the female I use to have there too.
He was just plain ugly when I picked him up. I was shocked, because when the woman at the pet store called me to say he'd arrived and I could come pick him up, she said, "Oh, and he's beautiful". She must be a tard!

She's the one there that orders all the reptiles in the store and she told me she owns and loves reptiles (don't know what kind).
I don't think the breeder gave him good care at all!
He had long, brown, skinny, spider-like legs. 
He was very stressed and dark brown in color with black & olive green markings. His cask is slightly bent and very thin/skinny. He almost never pooped. The next day when I decided to look at him closer I noticed a slightly swollen elbow, and it got much worse quickly, swelling spread down the leg/entire foot. It took four days before the vet specialist could see him and he had a bad infection. I didn't see a puncture so I don't know how it started, but the tip of his tail looks very chewed-on so he may have gotten in a fight. He has bred with a female before (so the breeder reports). I think I have him on the way to recovery, his color is nicer, I hydrate a lot, he's eating now and pooping (thank god), the swelling in the elbow has gone down a lot in the last 24-48 hours. It was on 1/13/2011 when I took him in to the vet.
