Tics are movements or sounds that are repeated over and over.
A person with a tic can't control the movement or sounds. Tics usually last less than a year. Throat clearing and eye squinting are common tics. Tics are often worse when a person is stressed, tired or anxious. Some medicines make tics worse.
