Over the course of several months I've been having strange things happening with my mouth. I don't know if these are things I should really be worried about or if I'm just being paranoid. The first symptom happened in June of last year, when I had a slight scratchy throat for about a month combined with a feeling something was stuck in my throat. I wasn't sick, but my throat was irritated. I didn't go to a doctor because my insurnace only allows me one physical a year and I had already had mine. Eventually it went away and hasn't come back sense.
Then in October or November I noticed a slight red spot on the side of my tongue. Then a few weeks ago I noticed a red crater like spot on the opposite side of my tongue. It has since almost disappered. About a week ago I had this combination of a tingling and numb feeling in the middle of my tongue. I don't know what was causing it but it went away in a few days. And just today while I was examining my mouth in the mirror I noticed a black line under my tongue that wasn't there yesterday. I've never smoked before, and I know sometimes a drinking problem can contribute to Oral cancer but I don't have that either. Am I being paranoid or is there something going on?
