Casey, sometimes with these snakes it's best to step back. Assess the whole situation, including husbandry, routines, etc. not just the one single action the snake did. Also to look for patterns of behaviour, look for whether this was a one time odd reaction or a new and different behaviour developing. Then back to the assess the whole situation thing...is the behaviour a good one and natural development of the snake or an iffy behaviour that concerns you. Is the behaviour something you are doing or not doing that triggers it. That sort of stuff.

If you ever feel though that your snake needs to see a vet, you go or at least phone your vet. It's always best, in the end, if your instincts say something is really, really not right to see a vet and get your concerns addressed by a professional who can do a hands on exam.
