[Jezebel doesn't try to stop him from moving his arms -- as long as his head stays level, it shouldn't do too much to him.]

I admit I don't know enough about this type of torture to say for sure, but I imagine this will have been the worst of it. If the voltage had been higher, it might have done worse, but then, it probably would have just killed you outright. Since you're still conscious and moving, I think with some rest you'll be recovered from this faster than the lashes.
