Can I ask you to describe it? Can you see it in a mirror?
How long have you had it?
Is there any coating on your tongue, or the inside of your cheeks?
Are you a smoker? Do you use any sort of inhalers?
How is your general health? Do you take any medication?
Sorry about all the questions, but the more information I have the better I can help.
