I have always had a little bump under my tongue for as long as I can remember. I imagine my dentist would see it when I would get my oral screenings after dental cleanings. I never thought much of it until now. I've been sick with a sore throat and now I've noticed its red. It's always been protruding but now it looks inflammed. What should I do? Is this a normal part of the mouth anatomy and it's inflammed because I'm sick? Or should I be worried this is some type of cancer? Please help, I'm terrified.
