I, too, have had a slight fever, but severe pain from ulcers on
the roof of my mouth. The pain is from the tip of my tongue to the root, palate, throat, and even to my right ear. An MD glanced at my mouth and said I have a few ulcers and offered only some numbing mouthwash. I want to know why this is happening, not put a bandaid on it.
Have you gotten information on your similar problem?
