distal and proximal joints of the middle and little fingers. The fingers have been compulsively picked and chewed in someone with<unk>  and dermatophagia. Compulsive picking of the face using nail pliers and tweezers Episodes of skin picking are often preceded or accompanied by tension, anxiety, or stress. In some cases, following picking, the affected person may feel depressed. During these moments, there is commonly a compulsive urge to pick, squeeze, or scratch at a surface or region of the body, often at the location of a perceived skin defect. When picking one may feel a sense of relief or satisfaction. The region most commonly picked is the face, but other frequent locations include the arms, legs, back, gums, neck, shoulders, scalp, abdomen, chest, and extremities such as the fingernails, cuticles, toenails, etc. Most patients with<unk>  report having a primary area of the body that they focus their picking on, but they will often move to other areas of the body to allow their primary picking area to heal. Individuals with<unk>  vary in their picking behaviour; some do it briefly multiple times a day while others can do one picking session that can last for hours. The most common way to pick is to use the fingers although a significant minority of people use tools such as tweezers or needles. Skin picking often occurs as a result of some other triggering cause. Some common triggers are feeling or examining irregularities on the skin, and feeling anxious or other negative feelings. This anxiety most commonly stems from a type of OCD which can range in severity and often goes undiagnosed. Complications arising from<unk>  include infection at the site of picking, tissue damage, and sepsis. Damage from picking can be so severe as to require skin grafting. Severe picking can cause epidermal abscesses. Severe cases of<unk>  can cause life-threatening injuries. For example, in one reported case a female picked a hole through the bridge of her nose, which required surgery to fix, and a 48-year-old female picked through the skin on her neck exposing the carotid artery. Pain in the neck or back can arise due to prolonged bent-over positions while engaging in the behavior. Besides physical injuries,<unk>  can cause severe physical scarring and disfigurement.<unk>  can cause feelings of intense helplessness, guilt, shame, and embarrassment in individuals, and this greatly increases the risk of self-harm. Studies have shown that<unk>  presented suicidal ideation in 12% of individuals with this condition, suicide attempts in 11.5% of individuals with this condition, and psychiatric hospitalizations in 15% of individuals with this condition.
