What to Do If You Have Blood Under Your Nail: Dermatologist Advice - Dermatology

More Info

---

If you have blood under your nail, it is important to assess the situation carefully. The presence of blood indicates that there has been some trauma to the nail bed, which can occur from various activities such as hitting your finger, crushing it, or even from certain nail treatments. Here’s a comprehensive guide on what to do next, along with some dermatological advice.


Immediate Steps to Take
1. Assess the Injury: First, determine the extent of the injury. If the nail is intact but discolored (black or dark red), it may be a subungual hematoma, which is a collection of blood under the nail. If the nail is broken or there is significant pain, you may need to seek medical attention.

2. Clean the Area: Gently clean the area around the nail with soap and water. Avoid using alcohol or harsh chemicals, as these can irritate the skin and nail bed.

3. Pain Management: If you are experiencing pain, over-the-counter pain relievers such as ibuprofen or acetaminophen can help alleviate discomfort. Follow the recommended dosage on the packaging.

4. Monitor for Infection: Keep an eye on the injury for signs of infection, which can include increased redness, swelling, warmth, or pus. If you notice any of these symptoms, it is crucial to see a healthcare professional.


When to Seek Medical Attention
- Severe Pain: If the pain is severe and not manageable with over-the-counter medications.

- Nail Loss: If the nail becomes loose or falls off, it’s important to consult a doctor.

- Signs of Infection: As mentioned, if you observe any signs of infection, you should seek medical help.

- Persistent Symptoms: If the discoloration does not improve or if you have concerns about the appearance of the nail.


Treatment Options
1. Drainage: If the hematoma is large and causing significant pain, a healthcare provider may need to drain the blood. This is typically done by creating a small hole in the nail to relieve pressure.

2. Nail Care: If the nail is intact, keep it clean and dry. You can apply a bandage to protect it from further injury. If the nail is damaged, it may take time to grow out fully, and you should avoid any activities that could further injure the area.

3. Moisturizing: Keeping the surrounding skin moisturized can help with healing. Use a gentle moisturizer or petroleum jelly to keep the area hydrated.

4. Avoiding Trauma: Be cautious with the injured finger to prevent further trauma. Avoid activities that could put pressure on the nail until it has healed.


Long-Term Care
- Nail Growth: Nails grow slowly, and it may take several months for the discoloration to resolve completely. As the nail grows out, the dark area will gradually move toward the tip of the nail.

- Healthy Nail Practices: Maintain good nail hygiene by trimming your nails regularly and avoiding biting or picking at them. This can help prevent future injuries.


Conclusion
In summary, if you have blood under your nail, it is essential to monitor the injury closely and take appropriate care. Most cases of subungual hematomas resolve on their own, but if you experience severe pain, signs of infection, or if the nail is significantly damaged, seeking medical attention is crucial. Remember to practice good nail hygiene and protect your nails from trauma to promote healthy growth and recovery. If you have any concerns, don’t hesitate to reach out to a dermatologist or healthcare provider for personalized advice.
