Hi, Cindy. My son just turned 14. He used to have A LOT of headaches, too. His dr.'s just blew us off. So, the only conclusion we could come to was that they were allergy related--he has hayfever. Sinus Tylenol has brought him the best relief we could find. I used to give him "bee pollen" tablets when he was younger, hoping to increase his pollen tolerence level--I think it helped, because his hayfever hardly ever bothers him now. I also make him use "Nasalcrom" nose spray now when pollen levels are very high in our area. He used to miss a lot of school & everything else, too. He used to wake up with a really bad headache, then usually started vomiting. He has hardly had any headaches for the past two years. I don't know if they were CAH related or not, but the more I read on these boards, the more I really think they were!
