Oh wow, that's about as strange a diagnosis as I've heard. Is this vet really a good reptile vet ? I wonder how he got a wound in back of his throat....it would have possibly been from swallowing something sharp or being poked by an instrument like small forceps or something. Or could have swallowed an insect that was pretty large and bit him on the way down. Were you in the room when the vet looked down his throat ?
Anyway, hopefully everything will clear up and he will be fine ASAP.
