Hello all ^^

I picked up a pair of ball pythons at the Tampa Repticon, and have noticed a very severe problem with my female.

She has a very severe neck issue... I am not sure if it is merely a muscle spasm, a kink, or a possible broken bone or pulled nerve. I am really very worried about her though, as she appears to be very agitated (As if in pain) all the time, and it prohibits movement (She's always getting it caught on things.)
I have not fed her yet (She was fed the day before Repticon, which was yesterday.) and am also worried about how eating is going to work.
As far as I know, she was not like this when I first bought her. If she was, perhaps I just didn't notice it.
Possible cause? 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?

I have tried to work her spine with my fingers, and have also tried gently pulling on either side of the spot to see if it would perhaps give, but nothing. It's been two days though, so it's not a stress thing.

I really have utterly no idea what to do, and as a first time BP owner, would accept any help or opinions given.
