I have a nine year old son, who sometimes acts peculiar when we go to the movie theatre or out to dinner. He will get sick and complain that he fills nauseous and has difficulty breathing. He walks really stiff with his shoulders hunched and although I repeated ask him what is wrong, he tells me he is fine. Today, we had to leave the movie early because he was breathing so heavy as to appear to growl and complained that he was about to vomit. When we got home, he was fine and said that he was not acting sick or breathing funny. This happens quite often. He also does poorly in school. His teachers say he does not pay attention to anything going on in class and does his work very slowly and very sloppily.
