Fatigue and pain from tics

One of my major tics is to tilt my head to the side and stretch the long muscle in my neck, one side then the other, tilt my head up to do the muscle under my chin, move parts of my mouth (make a grimace or :| face) to move different muscles around my jaw/neck and scrunch my nose. It hurts so much after doing it for hours on end, and makes me so fatigued and sore. I don't know what to do to help it, but it literally feels like tearing my muscle at some point :(
