Any ideas on what might be wrong with my 10 year old?

Mostly during active play, my son often complains about being dizzy and his head hurting. At school, he often goes to the nurses office complaining of his "stomach hurting" and his head hurting or feeling dizzy. Sometimes he feels like he's going to vomit but he never usually does. He sometimes also complains about his "neck" hurting him. He doesn't usually complain about all of the symptoms together, it seems to be different depending on the activity level. During school it's mostly his stomach, during moderate play it's mostly his head. He doesn't complain as much about his "neck" hurting, but when he does he is not doing much. Have any idea on what might be going on? I have no idea if I should take him to a neurologist, psychiatrist, endocrinologist, or cardiologist. Thanks!!

He has different symptoms during different situations it seems. At school it's more of his stomach, kind of like he's about to vomit but I think he gets dizzy sometimes too. During activity, he gets dizzy and says his head hurts. He's fine when he is just sitting at home doing nothing.

He has actually been tested for allergies, it was all negative.  No cough, itchy eyes or sore throat. Had his ears checked out too. He eats fine, seems to like school. There are several things it could be. I don't know if he says his head hurts because he's dizzy or his head really hurts as another symptom.

It has been a year or more of strange symptoms, especially for children, have you considered it may be allergies. Does he have a cough, itchy eyes, sore throat ? I would take him to your regular doctor and see what he thinks ..How is he eating, does he like school and do well there ?
