Your Open Question

Why is my son's underarm temperature always several degrees more than if I take it orally?
My 13 yr old son gets frequent fevers (he is being observed for possibly having Still's disease.) He can typically tell when he has a fever, and he's always right. However...the majority of the time, his oral temperature will show normal but his underarm temp will show a fever. Sometimes it is 3-4 degrees higher than the oral reading. I have always had this problem with his temp. Does anyone know why this could be or what could cause this? I'm very confused. I've asked drs but they all just look at me like I'm crazy, but yet they never take his temp under his arm. They always take orally or in the ear. Any input would be helpful! Thanks
(Also, when his underarm reflects a fever, he also shows other symptoms: Warm to touch, glassy eyes, general ill feeling, etc)
