I don't think you should panic! I have facial numbness and my tongue feels like it has been mildly burned...like on the hot coffee or something. Mostly on the AN side. So, is your nose cold? I sound like I should be a "healthy dog"...because my nose is cold and damp all the time!! A drippy cold nose does not make one feel very attractive, let me tell you. That Trigeminal nerve gets upset over having that tumor in there, and all sorts of things act up. Do you have the metallic/salty taste in your mouth? Kind of alters the taste of food, but I'm grateful I have any taste at all. But, any concerns you have be sure to talk with your doctor. Best to talk to the professionals to allay (is that a word?) your fears.
