Hi T.,
I don't know anything about your child's behavior,but if it bothers you, get him to a specialist, NOW! If it is nothing, then you will sleep better! If it were me, I would take him straight to a pediatric neurologist, perhaps at a Children's Hospital or a teaching hospital like UCLA. I have always gone straight to the top and it has paid off.
I have 3 children, ages 20,15 and 13. I am an attorney, but have only worked parttime for most of their lives. They are all amazing, out going,and fun-loving. My eldest has had 4 eye surgeries, my middle one has problems with her knees and my youngest has type 1 diabetes.
In each of these situations,there were signs and behaviors that bothered me. I didn't know what any of it meant, I just knew that I was concerned. Other people told me it was no big deal, I was just a nervous mom. Fortunately, I didn't listen and I took each of them straight to a specialist. In each situation, my early response saved my children from serious complications.
I know it sounds like they are very sick kids, but nothing could be further from the truth. Due to my immediate attention to things that "bothered me", they are all healthy and active. They all have black belts, one is in college for dance, the second plays lacrosse and swims and the diabetic play tackle football!
Go with your gut and get the best help available. If you are wrong and it is nothing, then HURRAH!
