I know when i had a reaction it was like i couldnt sit still, i had to keep bouncing my leg or get up and pace i just felt nervous like if i would stop moving something bad would happen. Im not sure if what you described is a case of TD but i know you dont wanna hear it again perhaps you should talk to your pdoc about it, it could be nothing, or a wierd spasm. I hope all goes well with your next vist.
