Treating Compulsive Nail Biting

Tips and Strategies to Stop Compulsive Nail Biting

Compulsive nail biting is a body focused repetitive behavior that results in the destruction of one's own fingernails and often the skin around the nails and cuticles. People who suffer from compulsive nail-biting may experience bleeding, bruises, infections, or even permanent damage to the fingers.
The behavior is often unconscious, and people with this compulsion may have difficulty stopping because they may be unaware of their actions.

Keep the Hands Busy

Fidget toys to keep the hands busy can be an important aid in treating difficulties like compulsive nail biting.
A pocket koosh ball is a good way to occupy the fingers.
