Blood Under The Nail Causes, Treatment, And Prevention Tips

Blood under the nail, also known as a subungual hematoma, is a common condition that can cause significant pain and discomfort. It occurs when blood vessels beneath the nail bed rupture, leading to blood pooling under the nail. This can happen due to various reasons, ranging from minor injuries to more serious trauma. Understanding the causes of blood under the nail is crucial for effective treatment and prevention. This article delves into the various causes, explores different treatment options, and provides practical prevention tips to help you maintain healthy nails.

Understanding Blood Under the Nail

Before diving into the causes, treatment, and prevention, it's essential to understand what subungual hematoma entails. Blood under the nail typically presents as a dark red or purplish discoloration beneath the nail plate. The pressure from the pooled blood can cause intense throbbing pain, especially if the hematoma is large. In some cases, the nail may even detach from the nail bed. This condition is not only painful but can also be unsightly, affecting the overall appearance of your hands or feet.

The nail unit comprises several parts, including the nail plate (the hard, visible part of the nail), the nail bed (the skin underneath the nail plate), the nail matrix (where the nail cells are produced), and the surrounding skin. When an injury occurs, blood vessels in the nail bed can rupture, leading to bleeding. Because the space under the nail is limited, the blood accumulates, causing pressure and pain. The severity of the condition often depends on the size of the hematoma and the amount of pressure it exerts on the surrounding tissues.

Subungual hematomas can affect anyone, regardless of age or gender. However, individuals who participate in sports, engage in manual labor, or have certain medical conditions may be at a higher risk. Recognizing the early signs of blood under the nail can help in seeking timely treatment and preventing further complications. The initial symptom is usually a sharp, throbbing pain, followed by the appearance of discoloration under the nail.

Common Causes of Blood Under the Nail

Identifying the causes of blood under the nail is the first step in addressing the issue effectively. Various factors can lead to a subungual hematoma, and understanding these can help you take preventive measures. Here are some of the most common causes:

1. Trauma and Injury

The most frequent cause of blood under the nail is trauma or injury to the nail. This can occur from a direct blow, such as hammering a nail and missing, stubbing your toe, or dropping a heavy object on your foot or hand. Even repetitive minor traumas, like wearing shoes that are too tight, can cause blood vessels to rupture over time.

Direct trauma causes immediate bleeding under the nail, resulting in a visible hematoma. The impact's force can damage the small blood vessels in the nail bed, leading to blood accumulation. The pain associated with this type of injury is often intense due to the pressure build-up. Depending on the severity of the trauma, the nail might also separate from the nail bed, a condition known as onycholysis.

Repetitive minor traumas, on the other hand, may not cause immediate symptoms. Instead, the bleeding occurs gradually over time. This type of injury is common among athletes, especially runners and hikers, who subject their feet to repetitive stress. Ill-fitting shoes can exacerbate the problem by putting pressure on the toes, leading to micro-traumas that eventually result in blood under the nail. It's crucial to ensure that footwear fits properly and provides adequate support to prevent this type of injury.

2. Sports and Physical Activities

Engaging in sports and physical activities can increase the risk of developing blood under the nail. High-impact activities, such as running, soccer, basketball, and tennis, often involve repetitive movements and sudden stops and starts, which can cause trauma to the toes and fingers. Athletes who participate in these sports are particularly susceptible to subungual hematomas.

Runners, for example, often experience blood under the toenails due to the constant impact of their feet against the inside of their shoes. This condition, sometimes referred to as “runner’s toe,” is more common in long-distance runners and those who train frequently. Similarly, soccer players are at risk due to the frequent kicking and contact with the ball and other players. The impact can cause direct trauma to the toenails, leading to bleeding under the nail.

Athletes should take preventive measures to minimize the risk of developing subungual hematomas. This includes wearing properly fitted shoes, using cushioned socks, and ensuring that their nails are trimmed short to avoid additional pressure. Taping the toes can also provide extra support and protection during physical activities. Recognizing the risks associated with specific sports can help athletes and coaches implement strategies to prevent these injuries.

3. Tight or Ill-fitting Footwear

Wearing tight or ill-fitting footwear is another significant cause of blood under the nail, particularly in the toes. Shoes that are too small or narrow can compress the toes, leading to pressure and friction that can damage the blood vessels under the nails. This is especially true for individuals who spend long hours on their feet or participate in activities that require repetitive foot movements.

Tight shoes restrict the natural movement of the toes and can cause micro-traumas to the nail bed. Over time, these small injuries can accumulate, resulting in bleeding and hematoma formation. High heels, pointed-toe shoes, and shoes with a narrow toe box are common culprits. These types of footwear can exert excessive pressure on the toes, increasing the risk of developing subungual hematomas.

It is essential to choose footwear that provides ample room for the toes to move freely. When trying on shoes, ensure that there is enough space between the longest toe and the end of the shoe. The toe box should be wide enough to accommodate the toes without squeezing them. Investing in properly fitted shoes can significantly reduce the risk of developing blood under the nail and other foot-related problems.

4. Medical Conditions and Medications

In some cases, medical conditions and medications can contribute to the development of blood under the nail. Certain conditions can affect blood clotting or weaken blood vessels, making them more prone to rupture. Additionally, some medications can have similar effects, increasing the risk of bleeding under the nail.

Medical conditions such as diabetes, peripheral vascular disease, and certain autoimmune disorders can impair blood circulation and make blood vessels more fragile. These conditions can increase the likelihood of blood pooling under the nail, even with minor trauma. Similarly, blood clotting disorders can affect the body's ability to stop bleeding, leading to hematoma formation more easily.

Medications like anticoagulants (blood thinners) and certain anti-inflammatory drugs can also increase the risk of bleeding. These medications can make blood vessels more susceptible to damage and prolong bleeding time, which can result in subungual hematomas. If you are taking any medications that affect blood clotting, it is essential to be extra cautious and take preventive measures to avoid injuries to the nails. Consulting with your healthcare provider about potential side effects and precautions is always advisable.

5. Fungal Infections

Fungal infections of the nail, also known as onychomycosis, can sometimes lead to blood under the nail. The infection can cause the nail to become thickened, brittle, and distorted, making it more susceptible to trauma and bleeding. As the nail structure weakens, even minor impacts can cause blood vessels in the nail bed to rupture.

Fungal infections can create an uneven surface on the nail, which increases friction and pressure, especially when wearing shoes. The infected nail may also separate from the nail bed, creating space where blood can accumulate. Treating the fungal infection is crucial to prevent further damage and reduce the risk of subungual hematomas. Antifungal medications, both topical and oral, are commonly used to treat onychomycosis. It is important to follow the prescribed treatment plan and maintain good nail hygiene to prevent recurrence.

Treatment Options for Blood Under the Nail

The treatment for blood under the nail depends on the size of the hematoma and the level of pain. Small hematomas may heal on their own without medical intervention, while larger ones often require drainage to relieve pressure and prevent further complications. Here are some common treatment options:

1. Home Care and Observation

For small hematomas that cause minimal pain, home care and observation may be sufficient. The body can naturally reabsorb the blood over time, and the discoloration will gradually fade. However, it is essential to monitor the condition and seek medical attention if the pain worsens or signs of infection develop.

Home care typically involves resting the affected finger or toe, applying ice to reduce swelling and pain, and elevating the limb to minimize blood pooling. Over-the-counter pain relievers, such as ibuprofen or acetaminophen, can help manage discomfort. It is also crucial to protect the injured nail from further trauma by wearing comfortable shoes and avoiding activities that could exacerbate the condition. Regular observation is necessary to ensure that the hematoma is resolving and there are no signs of infection, such as increased pain, redness, or pus.

2. Draining the Blood (Trephination)

If the hematoma is large and causing significant pain, draining the blood can provide immediate relief. This procedure, known as trephination, involves creating a small hole in the nail to release the accumulated blood. Trephination should be performed by a healthcare professional to minimize the risk of infection and ensure proper technique.

Trephination is typically done using a sterile needle or a specialized tool designed for nail drainage. The healthcare provider will carefully puncture the nail over the hematoma, allowing the blood to drain out. This procedure can significantly reduce the pressure under the nail, alleviating pain and promoting healing. After drainage, the area is cleaned and bandaged to prevent infection. In some cases, a small splint or dressing may be applied to protect the nail and surrounding tissues.

3. Medical Interventions

In more severe cases, medical interventions may be necessary to address blood under the nail. If the nail is severely damaged or detached from the nail bed, a healthcare provider may need to remove the nail to allow proper healing of the underlying tissues. Additionally, if there is a fracture of the underlying bone, further treatment, such as splinting or casting, may be required.

Nail removal is typically performed when the nail is significantly damaged or there is a high risk of infection. The procedure involves numbing the area and carefully separating the nail from the nail bed. After removal, the nail bed is cleaned and dressed to promote healing. In some cases, a temporary artificial nail may be applied to protect the nail bed while the new nail grows in. Fractures of the underlying bone often require immobilization to allow proper healing. Splints, casts, or other orthopedic devices may be used to stabilize the injured area.

4. Antibiotics and Infection Management

Infections can sometimes develop in conjunction with blood under the nail, especially if the nail is punctured or detached. Signs of infection include increased pain, redness, swelling, and pus drainage. If an infection is present, antibiotics may be necessary to prevent the spread of bacteria and promote healing.

Antibiotics can be administered orally or topically, depending on the severity of the infection. It is essential to follow the prescribed dosage and duration of treatment to ensure that the infection is fully eradicated. Proper wound care, including regular cleaning and dressing changes, is also crucial in managing infections. If the infection is severe or does not respond to initial treatment, further medical evaluation and intervention may be necessary.

Prevention Tips for Blood Under the Nail

Preventing blood under the nail is often easier than treating it. Taking proactive measures to protect your nails can significantly reduce the risk of developing subungual hematomas. Here are some prevention tips for blood under the nail:

1. Wear Properly Fitted Shoes

The importance of wearing properly fitted shoes cannot be overstated. Shoes that are too tight or too loose can cause various foot problems, including blood under the nail. When choosing shoes, ensure that there is enough room for your toes to move freely and that the shoe provides adequate support.

Properly fitted shoes should have a wide toe box that allows your toes to lie flat without being compressed. There should be approximately a thumb’s width of space between the end of your longest toe and the tip of the shoe. When trying on shoes, wear the type of socks you would typically wear with them. Walk around in the shoes to ensure they are comfortable and do not rub or pinch any part of your foot. Avoid shoes with narrow toe boxes or high heels, as these can put excessive pressure on your toes.

2. Trim Your Nails Regularly

Keeping your nails trimmed regularly is essential for preventing injuries that can lead to blood under the nail. Long nails are more likely to catch on objects and be subjected to trauma. Trim your nails straight across and avoid cutting them too short, as this can increase the risk of ingrown nails.

Regular nail trimming helps maintain the integrity of the nail and reduces the chances of it being injured. Use nail clippers or scissors to trim your nails, and file the edges to smooth them out and prevent snags. Avoid cutting the nails too close to the skin, as this can damage the nail bed and increase the risk of infection. Trimming your nails after a shower or bath when they are softer can make the process easier and reduce the risk of splitting or cracking.

3. Protect Your Feet and Hands During Activities

During sports and other physical activities, it is essential to protect your feet and hands from trauma. Wear appropriate protective gear, such as padded socks, gloves, and sturdy shoes, to minimize the risk of injury.

Protective gear can provide a barrier against impacts and friction, reducing the likelihood of blood vessels rupturing under the nails. For example, wearing well-cushioned socks can help absorb shock and prevent trauma to the toes during running or other high-impact activities. Gloves can protect the fingers and nails during manual labor or sports that involve contact with objects. Choose gear that fits properly and provides adequate protection for your specific activity. Properly protecting your extremities can greatly reduce the risk of subungual hematomas and other injuries.

4. Avoid Repetitive Trauma

Repetitive trauma to the nails can lead to blood under the nail over time. If you engage in activities that involve repetitive movements or pressure on your nails, take steps to minimize the impact. For example, if you are a runner, ensure that your shoes fit properly and that you are using cushioned insoles. If you work with your hands, wear gloves to protect your nails from repetitive stress.

Minimizing repetitive trauma involves identifying activities that put stress on your nails and implementing strategies to reduce that stress. This may include taking breaks during repetitive tasks, using ergonomic tools, and adjusting your technique to reduce the force applied to your nails. Being mindful of how your activities affect your nails can help prevent chronic injuries like subungual hematomas. Addressing the underlying causes of repetitive trauma can also improve your overall comfort and performance in these activities.

5. Maintain Good Nail Hygiene

Good nail hygiene is crucial for preventing infections and other nail problems that can contribute to blood under the nail. Keep your nails clean and dry, and avoid biting or picking at them. If you get manicures or pedicures, ensure that the salon uses sterile tools and follows proper hygiene practices.

Maintaining good nail hygiene involves regular cleaning, proper trimming, and avoiding habits that can damage the nails. Wash your hands and feet regularly with soap and water, and dry them thoroughly, especially between the toes. Use a nail brush to clean under the nails and remove any debris. Avoid sharing nail clippers or other personal care items to prevent the spread of infections. If you notice any signs of a fungal infection, such as thickening, discoloration, or brittleness of the nails, seek medical treatment promptly.

Conclusion

Blood under the nail, while often painful and unsightly, is a common condition that can usually be managed effectively with proper care and treatment. Understanding the causes of blood under the nail, from trauma and ill-fitting shoes to medical conditions and infections, is crucial for prevention. By taking preventive measures, such as wearing properly fitted shoes, trimming your nails regularly, and protecting your feet and hands during activities, you can significantly reduce your risk of developing a subungual hematoma.
