Could continual headaches and occasional ear aches be connected?

I first got an account here about a month ago, asked a question (see question here), and disappeared quite silently. Poor etiquette, I know.
But anyway…
Well, it’s been a month, and the idea of stress-related issues has been ruled out. I’m still drinking the same amount every day (no worries – I’m not diluting nutrients in my system). I’m also having significant headaches, about which the doctor is worried. He wants to have an MRI done. My family is worried about me, and is trying to figure out if there’s anything less significant we can rule out before doing something so… drastic, I guess you would say, although that’s not the right word.
But anyway… In the last couple of days, I’ve been noticing something else: My ears have also been hurting pretty badly. It seems like these symptoms could be connected, even though it doesn’t make sense. What could this indicate? Is there a problem the doctor may not have thought of before, that the earaches would indicate? Or does this not make any difference?

Thanks for your input, everyone :)
