Symptoms. Tics are divided into simple or complex. Simple tics include shrugging the shoulders, making facial grimaces, blinking the eyes or other eye movements, repeated throat-clearing, grunting, and other vocal sounds. An example of a complex tic would be a shoulder shrug combined with a sniffing sound and a head twist. It would also include jumping, hopping, twisting, and bending. Vocal tics are also considered simple or complex. Simple vocal tics are sniffing, throat clearing, grunting, barking, and more. More complex tics involve phrases and words. Some people with TS repeat what others say in words or phrases. Rarely, a person will curse or say other inappropriate words. And more dramatically, one tic involves hitting oneself.
