hello. I have a 14 year old son who gets frequent headaches. He is very small for his age...has always been in the 5% or less for height and weight but recently has fallen to below the 1%. He has a very very small appetite - eats a little and says he is full. He has not entered purberty yet. We would like to understand the cause of his headaches and to make sure there is no underlying cause for them as well as for his growth. We don t know what kind of doctor to go to and our family doctor, unfortunately, has not been helpful. do you have any suggestions? my email is YYYY@YYYY
