Blood clots in the finger are uncommon but can be dangerous if left untreated. Blood clots under the thumbnail, known as subungual hematomas, are usually caused by an injury that breaks open the blood vessels underneath the nail. This results in blood collecting and becoming trapped, causing severe throbbing pain and pressure. While some subungual hematomas heal on their own within a few months, others may require medical attention to drain the blood and relieve pressure. This article will explore the various treatments for thumbnail blood clots and provide guidance on when to seek medical help.

What You'll Learn
Apply ice to reduce swelling and pain
Blood clots under the thumbnail are uncommon but can occur due to an injury. This condition is called subungual hematoma, and it occurs when blood vessels under the nail break open, causing blood to collect and get trapped under the nail. The trapped blood may appear as a red or purple mark, which may later turn dark brown or black. The nail may also feel tender or sore.
To stop a thumbnail blood clot from forming or to treat one that has already formed, apply ice to reduce swelling and pain. This process is called cryotherapy and it is a well-known method for treating soft-tissue injuries. It is important to note that while cryotherapy can help reduce pain and swelling, it does not speed up the healing process and may even delay it. Therefore, it is crucial to understand how to use ice therapy effectively.
When applying ice to a blood clot under the thumbnail, it is recommended to use an ice pack. Place a layer or two of fabric, such as a towel, between the ice pack and your skin to protect against frostbite. Apply the ice for at least five minutes, then remove it and wait 30 minutes before reapplying. You can repeat this process a few times a day, but be sure to avoid keeping the ice on for more than 20 minutes at a time. Remove the ice once the injured area feels numb.
In addition to icing, you can also try other home remedies such as resting the affected hand, keeping it elevated, and applying compression to reduce swelling. These methods can help encourage healing while you wait for the nail to grow out, which typically takes 6-9 months. However, if the pain is severe or the injury is serious, it is important to seek medical attention.

Use compression to reduce blood pooling
Compression therapy is a common treatment for improving blood flow in the lower legs, ankles, and feet. It involves the use of compression socks, stockings, boots, or bandages to apply gentle pressure to the affected area. This pressure increases blood flow throughout the body, reducing the amount of blood that can pool and fluid from building up.
Compression therapy is particularly useful for preventing blood clots and reducing swelling and pain in the legs. It is often used to treat orthostatic hypotension, which is when your blood pressure drops when you stand up, causing dizziness, lightheadedness, or nausea. Compression therapy can also help manage conditions such as chronic venous insufficiency and prevent deep vein thrombosis.
Compression therapy comes in various forms, such as socks, stockings, and bandages, and can be purchased over the counter or prescribed by a doctor for more specific conditions. It is important to ensure that compression therapy garments fit properly to avoid potential problems such as skin irritation, discomfort, or pain.
In the context of a blood clot in the thumbnail, applying compression to the affected finger can help reduce blood pooling and promote healing. This can be done by using a compression bandage or wrap to apply pressure to the area immediately after the injury. It is also recommended to keep the hand elevated to further reduce swelling.

Keep the affected area elevated
Keeping the affected area elevated is a recommended treatment for superficial thrombophlebitis, a type of blood clot that occurs in the veins under the skin, typically in the arms or legs. Elevating the affected limb helps to treat the pain and inflammation caused by the condition.
For those experiencing deep vein thrombosis (DVT), a blood clotting disorder that can cause dangerous complications, it is also advised to elevate the affected leg throughout the day. This is because elevating the affected area can help to increase blood flow to the heart, thereby preventing the clot from growing bigger and reducing the risk of another blood clot forming.
To elevate the affected area, it is recommended to raise the legs 6 inches above the heart. This can be done at different times throughout the day, and it is important to change positions often, especially during long periods of inactivity. For example, when travelling on a plane or a long car journey, it is advised to stand up and walk at least every half hour to encourage blood flow.
Alongside keeping the affected area elevated, there are other treatments for blood clots. These include taking anticoagulant medications, wearing compression stockings, and applying heat to the painful area.

Consult a doctor if the injury is severe
If you experience a severe injury that results in a thumbnail blood clot, it is important to take immediate action to stop the bleeding and seek medical attention. Here are some detailed steps to follow:
Recognize the Severity of the Injury
When faced with a thumbnail injury, it is crucial to assess the severity of the wound. If the injury is severe, such as a deep or large cut, a puncture wound, or a broken nail bed, it is essential to consult a doctor as soon as possible. Severe bleeding, intense pain, or signs of infection are all indicators that medical attention is necessary.
Apply Pressure to the Wound
While waiting for emergency services or transporting the injured person to a hospital, it is vital to control and stop the bleeding. Apply direct pressure to the wound using a clean cloth, bandage, or your fingers, and maintain firm and continuous pressure until the bleeding stops. If the wound is on the hand or arm, raise it above the head to slow down blood flow.
Use Ice to Constrict Blood Vessels
To facilitate clotting and stop the bleeding, apply ice wrapped in a clean cloth to the wound. This helps constrict the blood vessels and promote quicker clot formation.
Elevate the Affected Area
If the injury is on a lower limb, lie down and raise the affected area above the level of the heart. This will help to reduce blood flow to the wound and aid in stopping the bleeding.
Remove Any Objects in the Wound
If there are any objects embedded in the wound, carefully remove them if possible. This will help reduce further damage and facilitate the healing process.
Keep the Wound Clean
Ensure that the wound is cleaned with cool water, and use soap to wash the surrounding area, being careful to not get soap in the wound itself. If there is dirt or debris inside the wound, use clean tweezers to remove it.
Seek Medical Attention
Even if the bleeding stops, it is crucial to seek medical attention as soon as possible. Visit a doctor or an emergency department to ensure proper care and rule out any other serious injuries. A doctor may recommend further treatments or medications to prevent infection and promote healing.
Remember, these steps are intended for severe thumbnail blood clot injuries. For any life-threatening emergencies, call emergency services immediately and follow their instructions.

Treatments may include trephination or surgery
Blood clots in the thumbnail are uncommon but can occur due to injuries. Blood clots underneath the thumbnail are known as subungual hematomas. They are usually caused by direct blows or crush injuries to the distal phalanx, such as hitting your thumbnail with a hammer or slamming your finger in a door. The blood vessels under the thumbnail break open, causing blood to collect and become trapped under the nail.
Subungual hematomas can be very painful and cause throbbing pain. They can also lead to severe discomfort due to accumulating pressure beneath the nail. If the pain is severe or unmanageable, or if there is severe damage to the nail bed, it is important to seek medical treatment.
Trephination
Trephination is a simple procedure that can be performed to treat subungual hematomas. It involves creating a small hole in the nail plate to drain the accumulated blood and relieve pressure. This procedure is relatively painless and quick, usually taking less than one second. Several methods can be used for trephination, including electrocautery, needle puncture, or even a heated paper clip. The choice of method depends on the provider's preference and the available resources. It is important to note that trephination may not be effective if more than 1-2 days have passed since the injury, as the blood within the hematoma will likely have clotted.
Surgery
In some cases, surgery may be necessary to treat subungual hematomas, especially if there is significant damage to the nail bed or underlying tissues. Surgery involves removing the nail plate and repairing the injured area. This helps ensure proper healing of the nail and prevents complications.
