i have a six year old son who just happens to be sick all the time. I have been told by three different pediatricians that he has asthma, seasonal alergies. His cough is often real bad, he gets headaches, hear infections, loss of apetite, and fever, and he gets really irritable. I am also told that for his age he is slightly below avrage in hight and weight, but one other thing that concerns me is the fact that he has an avrage of one vowel movement per week, and he is often spaceing out in school. I dont know if all these symptoms are afiliated with one another or what could be wrong with him . What sudgestions would you have for me to get him tested for?
