could be just allergies! my son did the same thing and it turned out to be seasonal allergies.. dr, prescribed allergy eye drops. i forget the name but ask your dr. they sell them over the counter..
I HAVE A SON WHO IS 6 YEARS OLD, WHO TOO HAD THINGS LIKE THIS HAPPENING. AFTER MUCH READING, I LEARNED ABUOT TOURETTES SYNDROME. MY SON WOULD TILT IS HEAD TO HIS SHOULDER RALLY FAST ABOUT EVERY 2 MINUTES. I NOTICED THESE EPESODES CAME AND WENT IN CYCLES. READ UP ON TOURETTE AND TS+
My son glances downward on purpose. I've talked to him about it, and he says it's a habit. He also said sometimes he does it 3 times in a row, and if he bumps his shoulder on something he has to go back and bump the other one. Are these 2 things tics, OCD, ones a tic...one's OCD, or what?
As a first step, you should have your son evaluated medically, rather than try to speculate about what might be occurring. It is possible that he has been experiencing some irritation from the chemicals in the swimming water. It is also possible that he is displaying some tics, or involunatry motor movements (such as eye blinking, twitching of facial muscles, movement of the neck). If the behaviors are diagnosed as tics, the doctor will likely refer your son to a pediatric neurologist.
