I'm fairly certain tetanic contraction is not the issue here.
OP, your horse pulled a muscle, of course he's going to be sore on that shoulder. It's also common knowledge that soreness in one muscle will affect others.
I doubt seriously if the animal is having continuous spasms without muscle relaxation, as opposed to just being plain old sore.
If you fell down and pulled a muscle, wouldn't you feel sore? Doesn't a stiff neck affect the rest of your body? Same thing in horses.
If you're concerned that he may have torn something, consult a vet. Otherwise, just let him be for a few days until he stops presenting ouchy.
