The majority of people in your thread about him yawning told you not to worry about it. I still think as with some of your other threads that you've just got new keeper nerves. I just want to echo what most people here have told you and say that I don't take any of my animals (reptiles that is) for regular vet check ups. I have a herp vet right around the corner that I'll go see only if I suspect there's an issue.
I'm sure it's fine. If he was yawning before you put him in there I doubt the moving enclosure is the cause. My opinion? Leave him alone. By all descriptions you've given he's eating well and sounds healthy, but you moving him all over the place and constantly examing him because you're stressed is just going to stress him. By all means if this is bothing you that much take him to the vet, but then put him in his enclosure and leave him alone for awhile.
