Is it underneath? Like under the mouth? It's quite normal, they puff up to seem bigger. Probable still settling in. If you could post a pic, it can help clarify if it's an issue or not.

No not under his mouth like when he is scared this is my second chameleon but I'v never had a baby and the pictures aren't loading it's on the sides of his neck like he is puggy lol
I am no expert, but my male has Gullar Edema. Which looks something similar to this. But I am not saying that he has it. I am still researching the best I can to figure out how my 18mo male has got it.
