What is self-injury?
Self-injury, also called nonsuicidal self-injury or self-harm, means intentionally hurting your own body without the primary intention of dying. Cutting is one form, but self-injury can also involve burning, hitting, scratching, interfering with wounds or other ways of causing injury.
For many people, self-injury functions as a way to manage emotional pain, intense anger, numbness, dissociation or a sense of being overwhelmed. The behavior may create short-term relief, a feeling of control or a way to turn emotional pain into something physical and concrete. That relief is usually temporary, and shame or distress often follows.
Self-injury is not attention seeking in the dismissive way the phrase is often used. Even when someone wants another person to notice that they are hurting, that need for help deserves to be taken seriously.
Self-injury and suicide are not the same
Most nonsuicidal self-injury is not intended to cause death. Still, people who self-injure have a higher risk of suicidal behavior over time. The intention can also change during a crisis. That is why clinicians should ask directly about both self-injury and suicidal thoughts rather than assuming one automatically answers the other.
Signs and symptoms of self-injury
Self-injury is often hidden. A person may cover wounds, explain them as accidents or avoid situations where scars could be seen.
Possible signs include:
- Unexplained cuts, burns, bruises or scars.
- Frequent injuries with vague or inconsistent explanations.
- Wearing long sleeves or pants in situations where it seems unusual.
- Keeping sharp objects or other tools used for self-injury nearby.
- Strong emotional distress followed by visible relief or calm.
- Statements about feeling worthless, empty, numb or unable to cope.
- Withdrawing from other people or becoming increasingly secretive.
What can trigger an urge?
Triggers vary. Conflict, rejection, shame, trauma reminders, numbness, self-criticism or feeling emotionally trapped can all contribute. Some people self-injure when emotions feel too strong; others do it because they feel nothing and want to feel something.
Conditions that can occur alongside self-injury
Depression, PTSD, dissociative disorders and borderline personality disorder can all be associated with self-injury. Self-injury itself is not proof of any particular diagnosis.
Medical danger
Even when death is not intended, injuries can be deeper than expected, become infected or cause permanent damage. If bleeding will not stop, a wound is deep or gaping, there is loss of sensation, or you are concerned about infection or other medical complications, seek medical care.
The function matters
Two people can use the same method for different reasons. One may be trying to interrupt numbness, another may be punishing themselves, another may be trying to regulate intense anger. Understanding what happens immediately before and after self-injury helps treatment identify replacement skills that serve the same function more safely.
This is why simply removing an object may not remove the urge. Safety measures matter, but treatment also needs to address the emotional job the behavior has been doing.
Diagnosis and tests
There is no specific laboratory test for self-injury. A clinician evaluates the behavior, injuries, triggers, emotional function and any related mental health conditions.
Safety assessment
A provider should ask whether you have thoughts of suicide, whether the intent has ever changed while self-injuring, what methods are used and whether injuries have required medical care. Direct questions are about safety, not punishment.
Physical evaluation
Recent injuries may need medical treatment. A clinician can assess wound care, infection risk, nerve or tendon injury and whether tetanus or other medical follow-up is needed.
Mental health evaluation
A therapist or psychiatrist may ask about depression, trauma, anxiety, substance use, relationships, impulsivity and emotion regulation. The goal is to understand what the behavior is doing for you so treatment can replace that function with something safer.
You do not have to stop self-injuring before you are allowed to ask for therapy. Treatment is where you can work on stopping safely.
Safety plans should be specific
A useful plan identifies personal warning signs, internal coping strategies, people and places that provide distraction, people to contact for help, professional crisis resources and ways to make the environment safer. The plan should be created when you are able to think clearly, not invented from scratch at the peak of an urge.
Wound care is part of care
Seeking medical treatment for an injury is not “rewarding” self-harm. It is basic healthcare. Shame about how an injury happened should not prevent cleaning, suturing or other medical treatment when needed.
Treatment for self-injury
Psychotherapy is the main treatment. The approach depends on the person’s triggers, co-occurring conditions and level of risk.
Dialectical behavior therapy
Dialectical behavior therapy, or DBT, teaches skills for tolerating distress, regulating emotions, staying present and improving relationships. It is particularly useful when self-injury is connected to intense emotional swings or interpersonal crises.
Cognitive behavioral approaches
CBT can help identify thoughts and situations that trigger self-harm and develop alternative responses. Treatment may include creating a plan for what to do during an urge and practicing safer ways to get through the peak of distress.
Treating underlying conditions
If depression, PTSD, anxiety or another condition is contributing, treating that condition can reduce self-injury urges. There is no medication specifically approved to stop self-injury itself, though medication may help related psychiatric symptoms.
Higher levels of care
When self-injury is severe, frequent, medically dangerous or accompanied by suicidal intent, more intensive treatment may be needed. That can include partial hospitalization, intensive outpatient programs or inpatient care during an acute crisis.
Reducing access during high-risk periods
Creating distance from objects or environments used for self-injury can buy time when urges are strongest. This works best as part of a broader safety and treatment plan, not as the only strategy.
Outlook
People can stop self-injuring and learn other ways to manage distress. For some, the behavior occurs only during one period of life. For others, recovery takes longer and includes relapses.
A return to self-injury after a period without it does not erase the time you went without harming yourself. It is information that something became harder and the support plan needs attention.
Urges can outlast the behavior
Someone may stop self-injuring but still have urges during stress. Recovery can mean recognizing the urge earlier and using other skills until it passes.
Scars and recovery
Scars can bring complicated feelings. Some people want to cover them; others do not. You do not owe anyone an explanation. Recovery is about what you are doing now, not hiding every sign of what happened before.
Reduce exposure to content that intensifies urges
Images, detailed stories or communities that romanticize self-injury can increase urges for some people. Recovery-focused spaces should avoid turning methods or scars into competition. Curating what you see online can be a legitimate part of protecting yourself during vulnerable periods.
Living with self-injury urges
When an urge hits, it can feel urgent and specific: do this now or the emotion will not stop. One useful goal is not to solve your whole life in that moment. It is to create enough time for the urge to change.
Use your treatment plan, not improvisation alone
Work with a clinician to identify strategies that match your triggers. That may include contacting someone, changing your environment, using grounding skills, delaying action or engaging in a strong but safe sensory experience recommended by your treatment team.
Tell someone before the urge becomes a crisis
You do not have to wait until after an injury to reach out. A simple message such as “I’m having urges and need company” can be enough to interrupt secrecy.
Urges often rise and fall like a wave
An urge can feel permanent when it is at its peak, but intensity usually changes over time. Delaying action, changing location and contacting someone can create enough distance for the peak to pass. This is not about “just distracting yourself” from serious pain; it is about surviving the highest-risk part of the moment so deeper treatment can continue.
If you are supporting someone
Stay calm. Do not punish, shame or threaten. Ask whether they need medical care and whether they are thinking about suicide. Encourage treatment and take immediate danger seriously.
Recovery may require changing routines around secrecy
If self-injury usually happens in a particular place or time, consider how your safety plan can interrupt that pattern. Being around another person, moving to a shared space or scheduling contact during vulnerable hours can reduce the isolation that lets urges escalate unnoticed.
When to get urgent help
If you may seriously injure yourself, cannot stay safe, have suicidal intent or have a life-threatening wound, call emergency services or go to an emergency department. In the U.S., call or text 988 for the Suicide & Crisis Lifeline.
A note from Project Semicolon
Self-injury can become a private emergency exit: pain gets too loud, numbness gets too deep, and for a moment hurting your body changes what you feel. That does not make you manipulative or beyond help. It means you found a coping method that carries real risk.
You deserve more than surviving one urge at a time in secret. Treatment can help build other exits, ones that do not leave you injured afterward. You can tell someone before the next crisis. You do not have to prove how much you are hurting with your body.
