Danny,
I know what you mean about the "hearing problem". My husband (who has never had radiation) seems to have it, and it affects whichever ear is facing in my direction.
I still seem to have an issue with hard wax in the left ear canal (which is the side that received the heaviest radiation) and I have to go in from time to time to have it thoroughly cleaned out. For me it's not so much a problem with hearing as it is with pressure that builds up in that one spot.
