I'm wondering if it might not be related to the infection. I've had some that caused some pretty strange symptoms at times.

Not sure what to suggest except the same kinds of mouthwashes mrsD mentioned, and see if it doesn't resolve when the upper respiratory infection goes away. A call to your doctor couldn't hurt either, just to alert him/her.

Hi gang and thank you for your thoughts. Years ago I did indeed have a whiteish coating on my tongue so I know that Candida may have been a factor in the past. Over the years I have also periodically used Diflucan 200 mg /day on various occasions (generally for a month at a time).

However, although at the moment my tongue looks complete normal with no coating, I may give the Oragel a try.

Given my small-fiber issues over time I naturally thought (perhaps incorrectly then) that the small-fiber neuropathy might have spread to my mouth.

My tongue and lips have become super sensitive to chilli and soda drinks like diet coke. I put it down to PN in the mouth.
