Brian,
I feel like I've hijacked Steve's thread...but just one more comment. Husband actually had virtually no herpes/canker sore problems before cancer diagnosis. He actually brought that up to our ENT when he saw him.

After your last post, I wrote a letter and faxed it to our ENT.

Sometimes, I can't figure out what is being vigilant and what is being neurotic.

Thanks for your insights,
Anita
