Treating a smashed fingernail: use ice to reduce swelling and pain
A smashed fingernail is a common injury that involves trauma to the finger. It can lead to pain, stiffness, swelling, and bruising. To treat a smashed fingernail, it is recommended that you use ice to reduce swelling and pain.
When you smash your fingernail, the first step is to relieve the swelling and pain. You can do this by applying an ice pack to the affected area. Wrap the ice pack in a clean cloth to prevent cold injury to the skin and apply it for 15 minutes at a time, a couple of times an hour for the first few hours. Do not apply ice to your finger for more than 15-20 minutes at a time. You can also elevate your finger to reduce swelling. Raising your injured finger above your heart slows down the blood flow and reduces throbbing.
Over-the-counter non-steroidal anti-inflammatory drugs (NSAIDs) such as ibuprofen and naproxen can help reduce pain and swelling. Paracetamol is also good for relieving pain. Moving your finger can also help promote circulation. However, if you can't move your finger or begin to lose sensation in it, call your healthcare provider.
It is important to keep the injury clean. Gently clean the area with soap and water or an antibacterial rinse. Then, cover the wound with sterile gauze or bandages. Change the dressings at least twice daily.
While most smashed fingers don't require medical treatment, you should seek treatment if there are signs of a fracture, the injury looks severe, or the pain and swelling persist.

Managing pain: take over-the-counter painkillers like ibuprofen or Tylenol
Smashing your finger can be extremely painful and can lead to swelling, stiffness, and bruising. In the event of such an injury, it is recommended to apply ice to the affected area to reduce swelling and prevent bleeding. While minor injuries may heal on their own, it is important to seek medical attention if there is persistent bleeding or a broken finger.
To manage the pain, over-the-counter painkillers like ibuprofen or Tylenol (also known as acetaminophen) can be taken. Ibuprofen is a nonsteroidal anti-inflammatory drug (NSAID) that is commonly used to treat mild to moderate pain. It is available over the counter and can be taken orally as a tablet, chewable tablet, capsule, gel capsule, suspension, or drops. The recommended dosage for adults and children over 12 years is one dose every 4 to 6 hours as needed, not exceeding 6 doses in 24 hours. It is important to carefully follow the directions on the package or prescription label and consult a doctor or pharmacist if you have any questions.
Ibuprofen may increase the risk of heart attack or stroke, so it is crucial to inform your doctor if you have a history of heart disease, high blood pressure, or other relevant medical conditions. Additionally, ibuprofen should be used with caution in patients with pre-existing liver disease, and routine laboratory testing is recommended for those with renal impairment.
Acetaminophen, commonly known as Tylenol, is another effective over-the-counter option for pain relief. It is often recommended as an alternative to ibuprofen for people who may be at a higher risk for adverse effects from NSAIDs. Always remember to follow the instructions on the package and consult a healthcare professional if you have any concerns or if your symptoms persist or worsen.

Draining blood: use a heated paperclip to drain blood from under the nail
Smashed fingers are a common injury, often caused by trauma to one or more fingers. This can be the result of a hammer blow, a car door, desk drawer, baseball, or some other force. The injury can lead to pain, stiffness, swelling, and bruising.
If blood builds up under the fingernail, it can cause severe, throbbing pain. In such cases, a heated paper clip can be used to drain the blood and relieve the pain. This procedure should only be done if you are experiencing pain and if your healthcare provider instructs you to do so. It is important to note that this procedure is not recommended for cosmetic reasons.
- Wash the injured finger thoroughly with soap and water.
- Straighten a paper clip so that you have a straight edge.
- Using pliers, hold the paper clip and heat the tip in a flame until it is red-hot.
- Carefully touch the red-hot tip to the part of the nail where the most blood has collected. Do not push or apply pressure, simply place gentle pressure and allow the heat of the paper clip to burn through the nail plate.
- As the paper clip penetrates the nail, there may be a gush of blood. Remove the paper clip and use a paper towel to wipe away any excess blood.
- Soak the finger in warm, soapy water for 10 minutes, 3 times a day for 2 to 3 days.
- Clear or slightly bloody fluid may continue to drain from the nail for 2 to 3 days.
- If the pain and pressure return or if the pain does not go away, contact your doctor as you may have a more serious injury.
It is important to note that this procedure should only be done if you are experiencing pain and if your healthcare provider instructs you to do so. Additionally, while a smashed finger will often heal on its own, you should seek medical attention if you are experiencing persistent bleeding, if you think the finger is broken, or if there is an open wound.

Cleaning the wound: wash the wound with soap and water, then cover with gauze
After smashing your fingernail, it's important to clean the wound to prevent infection and promote healing. Here's a step-by-step guide to cleaning the wound:
Step 1: Wash with Soap and Water
Gently wash the injured finger with mild soap and warm water. Use a gentle motion to avoid causing further pain or damage to the wound. You can also use tweezers cleaned with alcohol to remove any dirt or debris that may be present in the wound. Make sure to dry your hands with a clean towel afterward.
Step 2: Apply Mild Pressure to Stop Bleeding
If there is bleeding, use a clean cloth to apply slight pressure to the wound to help stop the bleeding. It is important to act quickly to minimize pain and the risk of infection.
Step 3: Elevate and Apply Cold Compress
Elevate your hand above your heart to slow down the blood flow and reduce throbbing. Apply a cold compress or an ice pack wrapped in a clean cloth to reduce pain and swelling. Hold the ice pack for 10-minute intervals with 20-minute breaks or for 15 minutes a few times an hour for the first few hours.
Step 4: Cover with Gauze
Once the wound is clean and dry, cover it with sterile gauze or bandages. Change the dressing at least twice daily or as recommended by your healthcare provider. Keep the wound clean and apply OTC antibiotic ointment to prevent infection and promote healing.
Step 5: Monitor and Seek Medical Attention if Needed
Most smashed fingers start to feel better within three to four days. However, more severe cases may take a few weeks to fully heal. Monitor your finger for any signs of infection or increased pain. If the pain becomes severe or the pressure builds up under the nail, causing discomfort, it is important to seek medical attention. Your doctor may guide you on relieving pressure and preventing the fingernail from falling off.

When to see a doctor: if the injury is severe, seek medical attention
A smashed finger is a common injury that involves trauma to the finger. While most smashed fingers don't require medical treatment, you should seek medical attention if your injury is severe or the pain and swelling persist.
If you are unsure whether your finger injury is serious, it is always best to err on the side of caution and seek medical care. Even if there is no fracture, a severely jammed finger can lead to permanent joint deformity and stiffness if not given the appropriate treatment.
You should seek medical attention if you have a deep wound that may require stitches, if you suspect you may have broken your finger, or if symptoms don’t start to improve with basic treatment. If the injury involves the palm or any of the joints, such as a finger or the wrist, you should also seek medical attention.
If there is blood beneath the fingernail, do not drain it yourself unless your healthcare provider recommends it. Your healthcare provider may suggest draining the blood if it is causing you pain. They may use a heated wire to burn a hole through the nail to relieve the pressure and reduce swelling. In some cases, the nail may fall off, but this is usually nothing to worry about as it will likely grow back.
