I am worried that my five year old has TS. My other kids do not have it. He at first would clear his throat a lot. I took him to doctor and they found nothing but gave him allergy meds which seem to help that problem. Then he started moving his tounge a lot. Now he makes a sound like hum..a lot..and twist his mouth a lot. I do not think that I can explain what he does. He is very sensitive. My nephew was jerkin his neck and blinking his eyes constantly. I am taking him to doctor and psychologist to find out what it may be. Any helpful suggestions if it is TS?
