Severe Neck Kink - Help?

[rabernet]

I have an appointment with my vet scheduled for this Friday (The soonest possible, unfortunately). I have opened myself to the possibility that I may have to put her down.
I've talked to several vets via email though so far, and all have said that it is very unlikely that the injury was caused by her being held still by her neck (Details on that, he wasn't holding her just by her neck, he supported her body as well).

@AMgsarchie: Yes, I expect it to be believed, as I have utterly no reason to tell any falsehoods here. With the way it is bent, when she is coiled up it looks completely natural, and is only see-able when she has her neck straight. My brother is in the rattlesnake industry and was holding her to check for any problems that I may not have been aware of, as he usually does when I buy my corns. She was not being held on the drive home, this was while we were still at Repticon.

She no longer acts as if she is in pain, and is very social and docile. Perhaps she was just stressed (Thus her behavior), but she doesn't act as if it pains her right now.

My brother was holding her on the way home and she attempted to strike at him, so he grabbed her by the back of the neck to hold her still. Could this have caused something to go wrong?

Something doesn't jive......
