The clinical name for the nail biting is â€œchronic onychophagiaâ€.
Mostly nail biting starts from the childhood and it gradually becomes habit as a person grows up. And if this habit is because of nervous condition then instead of removing the habit we should try to find the condition and treat it. We can find these conditions with the help psychologist and during process you will come across certain things that you do not remember consciously for long time.
Nervous condition is a condition which has developed in the childâ€™s growing stage but triggered later or comes up later on a certain happening or event. Many doctors believe that unless you come across that happening or event you never go for nail biting. So in this case it is more important to find the condition than to try removing habit.
A person many times start biting his finger nails or toe nails when he or she is in stress, feeling boredom, hunger or in nervousness and wants to get rid of these by biting their nails. It can also be caused due to mental, emotional or physical disorder.
