Thats a spur not a String.. If you have other BP's how do you not know what a Spur is? As far as the pic of when you said her neck turned red i don't see anything wrong unless your telling me she sat there with her mouth open for a long time. I take pics when my snakes open their mouth too, like yawning, Hissing etc... you mentioned she was in the "S" position when it happened. A mouth open with a Hiss in the S position is when their Pissed and ready to Strike.
As far as all the other stuff about a Vet being out of the way ... Thats no excuse. If your snake has a RI and you ponder about the distance and whats convenient you'll end up with a dead snake.
Good luck with her.. Seems like you need to do a lot of Basic research about Ball Pythons.
