I used to bite the skin around my fingers and the skin looks damaged. it has no pain and the skin hasnt healed for almost a year now. is it something to worry about? how can i heal the skin?

Onychophagia: Or the nail biting disease has psychological roots and once the behavior is addressed nails return to normal in few weeks to months. Habit reversal therapies as well as the use of nail polish with bitter taste and otherwise not harmful to the body have been used. If skin and nail changes persist past few months after stopping nail biting a dermatology eval will be recommended.
