I had tourettes as a kid. I had rapid eye blinking without being aware I was even doing it. My Tourettes was a mild case and went away after a year or so. After the kids at school so cruely made me aware of what I was doing, I made efforts to be aware of blinking my eyes. Even now, at57 yrs old, I sometimes stop and think, am I blinking my eyes.
Most kids do out grow it but speaking from a kid that had Tourettes, I wish my parents would have taken me to see a doctor or neurologist for medication...even that even had medication for Tourettes back them. Kids can be so creul and it can cause self esteem issues down the line. There is medication to help control the Tourettes and if I were the parent, I would not hesitate to take my son to the doctor.
When children are growing up, a good portion of them have tics at one point or another. Only a small percent of kids who tic actually have tourettes.
Either way you shouldn't worry. It's a good idea to take him in to see if it's something serious, but it is most likely something he will grow out of. Thinking back to elementary/early middle school, there were a lot of people in my class who would tic, but almost everyone grew out of them.
Lastly, I think he is probably aware that he is doing it. When I was younger, I would always deny it if someone asked about it. "my eyes are just dry" or "I just have a cough"
To be diagnosed as tourettes syndrome, the tics have to last a year or more, and there must be at least 1 vocal tic, so by definition, right now, it isn't tourettes.
