I have developed a strange problem. My tongue hurts, stings, feels numb. I also have had a more than normal build of white substance on the back of my tongue. Now the irritation seems to have spread to the top of my mouth, and there are blisers on the back of my throat. About four months ago I started using a C-Pap breathing machine because of sleep Apnea. I probably have not cleaned the moisturizer as often as I should have. My guess is that I have grown some kind of fungus. I have stopped using the moisturizer. Yeah, I know I should have cleaned the moisturizer more often, but now that I have developed a problem does anyone have a suggestion to clearing up the mouth soreness. Maybe this has happened to somebody else out there, and you have a cure.
