is there a such thing as a lie bump on your tongue
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. Lie bumps are often caused by the taste bud(s) splitting.
