I have this painful bump on the side of my tongue. i've heard of it being called a lie bump. i need to know how to get rid of it.

Papilititis: The name "lie bumps" is a result of a myth that telling lies would cause them. However, very little has been written about this condition in scientific articles or textbooks and scientific studies have failed to produce a definite cause. Possible causes include: "stress, gastrointestinal upset, menstruation, acidic or sour food, smoking, and local trauma" (direct physical irritation) of the tongue
