I have been suffering from a bad case of canker sores, for a very long time now. It makes me very depressed, It gets to a point where i just don't want to live anymore. I get them in my mouth so bad that there must be about 15 of them in there when I do get them. I can't describe the pain that I am in. I would not wish this pain on anyone. Is there anyone out there that has a cure.
