Hi,
You need to find a vet with good knowledge of exotics rather than one who may have little experience.
Luckily we have lists of vets for you to check.
List 1.
List 2.
And even vets recomended personally by our members.
You could also ask the person you purchased from to see if he has any recomendations and the same holds true for local zoo's and pet stores.
Hope some of this helps.
**edit**
Did his neck still look like that when you took him to the vets?
