Hello.
From your description of your son's behavior, it does look like he needs an evaluation. For diagnostic advice, you can consult one or more of these kinds of specialists -
1) Child Psychiatrist or a Psychiatrist with special interest in ADD/ADHD
2) Child Psychologist
3) Occupational Therapist working with Children
You might come across many more mental health professionals, but you need to see if they are qualified for diagnosing ADHD.
Meanwhile, you can gather some tips from a few authentic websites about managing a child with hyperactivity.
Hope this helps.
