Hmm could just have been a mild one with the cold. Happens sometimes. I know whenever they say they're head hurts i immediately take their temp cause they usually don't say it otherwise.

@shananaginsx, thanks for the response(: I just thought it was odd but from what I'm aware of its his first headache. No fever since the Tylenol but now he just has cold symptoms.

That's how I always know they have a fever... Cause they have a headache. So yes, every time.
