Nail-biting, also known as onychophagia, is a common habit that involves biting or chewing the nails and often the surrounding skin. While it's usually not a serious medical condition, it can lead to various complications. Here's some information on symptoms, treatment options, and diagnosis related to nail-biting.

1. Bitten Nails: The most obvious symptom is nails that are bitten or chewed down to the quick.
2. Skin Irritation: Nail-biting can lead to irritation, redness, and even bleeding of the skin around the nails.
3. Infections: Biting nails can introduce bacteria from the mouth into small cuts or breaks in the skin, leading to infections.
4. Pain and Discomfort: Constant nail-biting can cause pain and discomfort in the fingertips and surrounding skin.
5. Cosmetic Concerns: Nail-biting can result in unattractive, jagged nails and damage to the nail bed.

1. Behavioral Therapy: Cognitive-behavioral therapy (CBT) or habit reversal therapy (HRT) can help individuals identify triggers for nail-biting and develop strategies to change the behavior.
2. Awareness Training: Keeping a diary or using awareness techniques such as wearing bitter-tasting nail polish or bandages on the fingertips can help individuals become more aware of their nail-biting habit.
3. Substitution Techniques: Finding alternative behaviors to replace nail-biting, such as squeezing a stress ball or playing with a fidget toy, can be helpful.
4. Reward System: Setting up a reward system for refraining from nail-biting, such as earning points or rewards for each day without biting nails, can provide motivation.
5. Professional Help: In some cases, seeking help from a psychologist or therapist who specializes in habit disorders can be beneficial, especially for individuals with severe nail-biting habits that interfere with daily life.

Nail-biting is typically diagnosed based on observation of the habit and its effects. There's usually no specific diagnostic test for nail-biting since it's a behavioral issue rather than a medical condition requiring formal diagnosis.
