My son is on no medications. He was at Parent/Children Night for high school tonight and had to talk to a lot of people. He does not make the best eye contact, and I noticed that, even when he knows someone well and is pretty comfortable with the person, he sort of looks off to one side and one eye seems to twitch a little bit. No doctor has ever mentioned it and I didn't notice it much before today because I rarely see him interacting with that many people. Does this sound like a tic? Is there such thing as a nervous tic that is not medically significant? He does not appear to have seizures and, in spite of being on the Autism Spectrum Disorders (ASD) spectrum, is not a spacey kid. I am thinking of taking him to the doctor, but I"m afraid it won't happen there...lol. Help?
