Amy,

Ear pain and headaches can be signs of any number of things, so if they persist it's best to have his doctor investigate. However, one thing that has caused ear pain (and some related headaches) for me is ear wax. I've heard that hard wax can build up following radiation, and I've had repeated instances where it was enough to cause real pressure. It was embedded sufficiently deep in the ear canal that the people in the local ear clinic said it had to be professionally removed (usually with some sort of probe and the world's smallest vacuum cleaner).

I hope the reason for John's pain can be easily found and remedied.
