Oh, I thought you just picked him up .
At any rate, he did well [ good genetics ] despite his neglect. And yes, I see a red spot but it's unclear and I'm not sure what it might be. You might p.m Tracie [ Drache613 ] who is one of the mods. to get her thoughts on it. He might have just bitten something that was hard and jabbed him.....so maybe keep an eye on it for a week to see if it changes at all. In the meantime try to find an vet that as lots of experience with reptiles in case you need to take him in.
One more thing.....although it's sweet that he's a snuggle bug, be careful of falling asleep with him. Latst year [ or so ] a poster wrote a very sad ending to her beardie's thread in the " bearde tale " forums. You guessed it....she fell asleep with him and rolled over + smothered her adult dragon. So even if it's unlikely, it's possible to hurt or kill them that way.
