What You'll Learn
See a doctor if you have a large bruise under your nail
If you have a large bruise under your nail, it is important to seek medical attention as soon as possible. This is because a large bruise could indicate a more serious injury, such as a broken bone or damage to the nail bed and surrounding tissues.
Your doctor may refer to the bruise as a "subungual hematoma". This occurs when there is bleeding under the nail, often as a result of trauma to the nail, such as slamming your finger in a door or dropping something on your toe. The blood pools under the nail, causing intense pain and throbbing as well as discoloration.
If you have a large bruise under your nail, your doctor may recommend a procedure called trephination or decompression. This procedure involves draining the hematoma to relieve pressure and pain. Your doctor may numb your finger or toe using a nerve block before making a small hole in the nail with a heated wire, laser, or needle. After the procedure, your doctor will bandage your nail, and you will need to keep your finger or toe elevated and bandaged for the first 12 hours.
It is important to see a doctor if you have a large bruise under your nail to rule out any other possible causes, such as skin cancer. Additionally, a large bruise under the nail can take a significant amount of time to heal, and proper medical care can help prevent future problems with your nail and provide much-needed pain relief.

Treat inflammation to reduce pain
A bruised fingernail is usually the result of an accident or injury. Blood collects under the nail, causing pressure and pain. This is known as a subungual haematoma. The pain can be intense and throbbing, and the nail may look discoloured.
To treat inflammation and reduce pain, you can try the following:
- Apply ice to the affected area. Wrap the ice in a soft cloth and apply it to the bruised nail. This will help to reduce swelling and pain.
- Elevate the affected area. Keep the hand or foot elevated to reduce swelling.
- Take over-the-counter anti-inflammatory medications. Medications such as aspirin, Advil, or Motrin can help to reduce minor pain and inflammation.
- Seek medical attention. If the pain is severe or gets worse, see a doctor or healthcare provider. They may recommend a procedure called trephination or decompression, which involves draining the blood from under the nail to relieve pressure and pain. This is a quick and painless procedure that can provide significant relief.
It is important to note that if you have a darkened area under your nail and haven't had any injury, you should consult a doctor to rule out other possible causes, such as skin cancer.

Apply ice and elevate the injured area
To help with a bruised fingernail, it is important to apply ice and elevate the injured area. This is because a bruised fingernail can cause severe pain, throbbing, swelling, and redness. Applying ice helps to reduce swelling by constricting blood vessels and numbing the area, thereby alleviating pain and inflammation. It is most effective when applied within the first 48 hours after the injury, in intervals of 15-20 minutes with breaks in between to prevent skin damage. Wrap the ice in a soft cloth or towel to create a barrier between the ice and your skin, which will prevent frostbite or ice burns.
Elevating the injured area while applying ice can help further reduce swelling. To do this, raise the injured finger above the level of your heart to slow the blood flow to the site, which will help reduce inflammation and ease throbbing pain.
It is important to note that a bruised fingernail can take months to look normal again and, in some cases, the nail may fall off. If there is significant injury to the base of the nail, trouble controlling bleeding, or severe pressure, it is recommended to call your doctor.

Use over-the-counter pain relievers
A bruised fingernail can be extremely painful, especially when blood collects under the nail, causing throbbing pain. The good news is that over-the-counter (OTC) pain relievers can help manage the pain and reduce inflammation. Here are some detailed instructions on how to use OTC pain relievers effectively to ease the pain of a bruised fingernail:
Firstly, it is important to select the right type of OTC pain reliever. Options include ibuprofen (e.g. Advil, Motrin) and naproxen, which are anti-inflammatory drugs that can help with both pain and swelling. Acetaminophen is another OTC option that helps with pain but not swelling. Always read the instructions on the packaging and consult a pharmacist or healthcare provider if you have any questions or concerns.
When taking OTC pain relievers, it is crucial to follow the recommended dosage. Do not exceed the maximum daily dose stated on the package or recommended by your healthcare provider. Additionally, be mindful of any potential interactions with other medications you may be taking. If you have a pre-existing medical condition, such as heart disease or kidney disease, or a history of stomach ulcers or internal bleeding, consult your healthcare provider before taking any OTC pain relievers.
For quick relief from the pain and swelling associated with a bruised fingernail, it is advisable to combine OTC pain relievers with other treatment methods. Apply ice to the injured area to reduce swelling and provide numbing relief. Elevate your hand above the level of your heart to reduce throbbing and discomfort. Keep the injured area clean to prevent infection, and consider using OTC antibiotic ointments or creams after cleaning the wound.
While your fingernail heals, it is important to rest the injured finger and avoid any activities that increase the pain. However, gentle movement of the finger can also aid in recovery by improving blood flow to the area. Gently massaging the injury site can help break up dead blood cells and encourage healing. Remember, if your symptoms do not improve with basic treatment or if you experience severe pain or loss of sensation, seek medical attention.

Seek medical attention if you can't move your finger
If you have a bruised fingernail, it is important to seek medical attention if you are experiencing any additional symptoms beyond the bruise itself. While bruised nails are typically minor injuries, they can sometimes indicate more serious underlying issues.
One reason to seek medical attention is if you are unable to move your finger. This could be a sign of a broken bone or fracture, which requires proper medical diagnosis and treatment. Untreated fractures can heal incorrectly, interfering with the natural function of your finger and potentially causing long-term pain and discomfort. Therefore, it is crucial to have an X-ray performed to determine if there is any bone damage.
Another reason to seek medical care is if you experience severe or persistent pain, especially if it is throbbing. This could indicate a subungual hematoma, which is a collection of blood under the nail that can cause intense pressure and pain. Your doctor may perform a procedure called decompression or trephination to relieve the pressure and drain the blood, providing significant relief.
Additionally, if you notice any signs of infection, such as pus, redness, heat, or persistent swelling, it is important to consult a doctor. They may prescribe antibiotics to treat the infection and prevent further complications.
Lastly, if you have not experienced any trauma or injury to your finger but still notice discoloration under your nail, it is important to seek medical advice. While it may be harmless, it could also indicate a serious underlying health condition, such as skin cancer, that requires prompt medical attention and treatment.

Frequently asked questions
A bruised fingernail is usually the result of an accident, such as stubbing your toe or slamming your finger in a door. The tissue under your nail becomes bruised, and blood collects under the nail, causing intense pain and throbbing.
Most minor subungual hematomas will heal over time without treatment. Home remedies such as resting, icing, gently massaging the area, applying compression, and elevating the hand can help encourage healing and improve recovery time. Over-the-counter anti-inflammatories and pain relievers can also help manage pain and reduce inflammation.
If you experience severe pain, bleeding that does not stop, signs of infection, or a subungual hematoma that does not go away on its own, you should seek medical attention. Additionally, if you notice discoloration or a bruise under your nail without any injury, contact your healthcare provider as it could indicate a more serious condition.
The recovery time for a bruised fingernail depends on the severity of the injury. Most minor cases start to feel better within three to four days, while more complicated or severe cases may take a few weeks or even months to fully heal. A new fingernail can regrow in as little as eight weeks, but it may take up to six to nine months for the nail to fully grow out and return to normal.
