A nail injury can occur when the nail is cut, torn, smashed, bruised, or torn away from the skin. This can be caused by a variety of things, including smashing your finger in a door, hitting it with a hammer, or cutting it with a sharp object. Treatment for a cut nail depends on the type and seriousness of the injury. Minor nail bed injuries, including subungual hematomas, often heal on their own, especially when no other injuries are present. However, more serious injuries may require a trip to the emergency room, where doctors can numb the finger or toe, drain blood, or remove and reattach the nail.

What You'll Learn

Clean the wound with soap and water
If you've injured your nail, it's important to clean the wound with soap and warm water. This is especially important if there are any cuts or scrapes around the nail, as proper wound care will help prevent infection.
To clean the wound, start by running warm water over the affected area. You can use a mild soap to gently wash the wound and the surrounding area. Be sure to remove any dirt, debris, or foreign objects that may be present. Take your time and be gentle, as the area may be tender or painful. If there is any dried blood or crusting around the wound, gently soften and remove it with warm water and soap. Avoid using hot water, as this may increase bleeding and irritate the wound.
It is important to use a mild, plain soap when cleaning a wound. Antibacterial or heavily scented soaps may irritate the wound and the surrounding skin. If you do not have access to mild soap, you can use a sterile saline solution or sterile water instead. Avoid using hydrogen peroxide, iodine, or alcohol to clean the wound, as these substances can be irritating and delay healing.
Once you have gently cleaned the wound, rinse away any soap residue with warm water and pat the area dry with a clean cloth or sterile gauze pad. Be sure to dry the area thoroughly, as moisture can promote bacterial growth and increase the risk of infection. If the wound is deep or if you notice ongoing bleeding, apply gentle pressure with a clean cloth or gauze to stop the bleeding before moving on to the next steps of wound care.
After cleaning and drying the wound, you may apply a thin layer of antibiotic ointment to help prevent infection and promote healing. Cover the wound with a sterile bandage or dressing to keep it clean and protected. Change the bandage daily, or more frequently if it becomes wet or soiled. Continue to monitor the wound for any signs of infection, such as redness, swelling, warmth, or pus. If infection is suspected, contact your healthcare provider for further advice and treatment.

Apply antibiotic ointment and bandage
If you have a cut nail, it is important to act quickly to prevent infection and promote healing. Here is a detailed guide on applying antibiotic ointment and bandaging a cut nail:
Clean the Wound
Before applying any ointment or bandage, it is crucial to clean the wound thoroughly. Wash your hands and the affected area with soap and warm water. If there is any debris or dirt around the wound, gently remove it using a clean cloth or gauze pad. Ensure that you do not rub or scrub the area, as this may cause further damage and increase the risk of infection.
Apply Antibiotic Ointment
Once the wound is clean and dry, it is time to apply a small amount of antibiotic ointment. This ointment will help prevent infection and promote healing. Gently apply a thin layer of the ointment to the affected area, ensuring that it covers the wound completely. If you have long nails, be careful not to get the ointment under your nails, as this can inadvertently introduce bacteria into the wound.
Bandage the Wound
After applying the antibiotic ointment, cover the wound with a sterile bandage. Choose a bandage that is large enough to cover the entire wound and secure it in place with tape or a bandage wrap. The bandage will help keep the wound clean and protected from further injury. It is important to change the bandage daily or whenever it becomes wet or soiled to maintain proper wound care.
Elevate and Ice the Area
To reduce swelling and throbbing pain, it is recommended to elevate the injured area above the level of your heart. Additionally, apply ice to the affected area for 15-20 minutes at a time, taking breaks as needed. This will help reduce inflammation and provide some pain relief. Remember not to apply ice directly to the skin, but wrap it in a thin towel or cloth to avoid ice burns.
When to Seek Medical Attention
While minor nail injuries can often be treated at home, it is important to know when to seek medical attention. If you experience signs of infection, such as redness, heat, or pus around the nail, or if you have not had a tetanus booster shot in over ten years, contact your healthcare provider promptly. Additionally, if there is any significant bending or deformity of the finger or toe, it may indicate a broken bone, and you should go to a hospital emergency department.

Manage pain with acetaminophen or ibuprofen
A nail injury can be painful, especially when the nail is cut, torn, or smashed. If you experience a nail injury, it is important to take care of it properly to prevent infection and promote healing. Here are some detailed instructions on managing pain with acetaminophen or ibuprofen after a nail cut:
When to Seek Medical Attention:
Firstly, it is important to assess the severity of your nail injury. If the injury involves any laceration (cut) or amputation of the nail, nail bed, or surrounding skin, seek medical attention at a hospital's emergency department. Additionally, if there is any part of the nail sticking out or pulled off the nail bed (nail avulsion), a large nail bruise, or any deformity in the fingertip, a medical professional should evaluate it.
Managing Pain with Acetaminophen or Ibuprofen:
If your nail injury is limited to a small nail bruise or minor cut, you can consider managing the pain with acetaminophen (e.g., Tylenol) or ibuprofen (e.g., Advil, Aleve). These medications can help reduce pain and make the healing process more comfortable. Here are some detailed instructions:
- Assess Your Health Condition: Before taking any medication, it is important to consider your medical history. If you have heart disease, high blood pressure, kidney disease, or a history of stomach ulcers or internal bleeding, consult your healthcare provider before taking acetaminophen or ibuprofen.
- Medication Choice: Acetaminophen is effective in managing pain, while ibuprofen helps with both pain and swelling. Choose the medication that best suits your needs.
- Dosage and Administration: Always follow the dosage instructions on the medication package or consult your healthcare provider for personalized advice. Do not exceed the recommended dosage.
- Combination with Other Treatments: Acetaminophen or ibuprofen can be used in conjunction with other home care treatments. For example, you can elevate your injured hand or foot above the level of your heart to reduce throbbing and swelling. Applying ice packs wrapped in a cloth for 20 minutes every 2 hours during the first day, and then 3 to 4 times a day thereafter, can also help manage pain and swelling.
- Monitoring and Follow-up: Continue to monitor your pain levels and adjust the medication dosage as needed, always staying within the recommended limits. If pain and swelling persist or worsen, or if you notice any signs of infection (such as pus, redness, or heat around the nail), discontinue the use of acetaminophen or ibuprofen and seek medical attention promptly.
Remember, while acetaminophen and ibuprofen can help manage pain associated with a nail cut, they are not a substitute for proper medical care. Always seek professional medical advice if you are unsure about the severity of your nail injury or if your condition worsens.

Elevate the injured area above the heart
If you have a cut nail, it is important to elevate the injured area above the heart to reduce throbbing and pain. This is because raising the injured area above the heart level can help reduce blood flow to the wound, which can help to reduce pain and swelling.
If you have cut your fingernail, sit or lie down and prop your hand up with a pillow or cushion. For a cut toenail, lie down and elevate your foot on a stack of pillows or a recliner.
Keep the injured area elevated above the heart for at least the first 24 to 48 hours, or as long as you can, to help reduce pain and swelling. You can also use ice packs wrapped in a thin cloth or towel to help numb the pain and reduce swelling. Apply ice for 20 minutes at a time, every two hours, during the first day. After that, apply ice 3 to 4 times a day.
If you have cut your fingernail or toenail and the nail is still attached to the nail bed, you may be able to treat it at home. Stop any bleeding by applying direct pressure with a clean cloth. If the nail is torn, use sterile scissors to cut off any rough edges to prevent further injury. Then, clean the wound and nail area with soap and warm water, and apply an antibiotic ointment to prevent infection. Cover the wound with a bandage and change the dressing daily.

Seek medical attention for serious injuries
If you have a cut or partially cut nail, it's important to assess the severity of the injury and take appropriate action. While minor nail injuries can often be treated at home, more serious injuries require prompt medical attention to ensure proper healing and the smooth growth of a new nail. Here are some guidelines on when to seek medical attention for serious nail injuries:
Lacerations and Avulsions
If the injury involves lacerations (cuts) that pierce the nail and nail bed, or avulsions where a portion of the nail is lifted or pulled off the nail bed, it is important to seek medical attention. These injuries often require professional treatment to ensure proper healing. Visit a hospital's emergency department for evaluation and repair. Do not pull or try to remove the nail from the nail bed.
Large Nail Bruise
A large nail bruise, known as a subungual hematoma, may require medical attention. If the bruise covers more than 25% of the nail or you wish to have it drained, consider going to the emergency department. The doctor may decide to drain the blood by creating a small hole in the nail plate to relieve pressure and pain.
Bone Fracture
If there is an obvious bend or deformity at the end of the finger or toe, it indicates a possible bone fracture. An X-ray will be needed to confirm the diagnosis. Seek medical attention for a suspected bone fracture, especially if it has been more than ten years since your last tetanus booster shot.
Infection and Complications
If you notice any signs of infection, such as pus, redness, heat around the nail, or a red streak extending from the wound, contact a healthcare provider promptly. Additionally, if you have other risk factors, such as diabetes, poor circulation, or chemotherapy, seek medical attention as these conditions can increase the risk of infection and affect healing.
Severe Pain and Swelling
While minor pain and swelling can be managed at home with ice and over-the-counter medications, severe or persistent pain and swelling may require medical attention. This could indicate a more serious injury or infection. If the pain and swelling do not subside within a week, consider consulting a healthcare provider.
