Getting blood trapped under your fingernail or toenail is a common, albeit unpleasant, experience. It can be caused by a variety of minor injuries, from slamming your finger in a door to a simple scrape. While often unsightly and potentially painful, removing the blood can significantly reduce discomfort and prevent further complications. This guide provides a step-by-step approach to safely and effectively remove blood from under your nail.
Why is Blood Under the Nail Painful?
Blood trapped under the nail (subungual hematoma) causes pain because it builds up pressure beneath a relatively inflexible structure. This pressure presses on the sensitive nerve endings in the nail bed, leading to throbbing, aching, and even shooting pains. The larger the hematoma, generally the more painful it becomes.
How to Remove Blood from Under a Nail: A Step-by-Step Guide
The most effective method depends on the size and severity of the hematoma. For small collections of blood, the body often reabsorbs the blood naturally within a few weeks. However, larger hematomas require intervention.
Method 1: Home Treatment (For Small Hematomas)
This method is suitable for smaller amounts of blood and should not be used on large hematomas.
-
Soak in Warm Water: Immerse the affected finger or toe in warm (not hot) soapy water for 10-15 minutes. This can help to slightly soften the nail and may encourage the blood to disperse.
-
Cold Compress: After soaking, apply a cold compress to the affected area for 10-15 minutes. This can help to reduce swelling and pain.
-
Elevation: Keep the affected digit elevated above your heart to minimize swelling.
-
Pain Relief: Over-the-counter pain relievers like ibuprofen or acetaminophen can help manage discomfort.
Method 2: Medical Intervention (For Large Hematomas)
Larger hematomas, those causing significant pain or showing signs of infection (redness, swelling, pus), require professional medical attention. A doctor may use one of the following methods:
-
Nail Trephination: This involves using a sterile needle or small drill to create a tiny hole in the nail, relieving pressure and allowing the blood to drain. This procedure is relatively quick, painless (with local anesthetic), and effective.
-
Surgical Removal: In rare cases, if the damage is extensive, the nail may need to be partially or fully removed.
Note: Do not attempt to drain the blood yourself using unsterile tools. This can lead to infection. Always consult a healthcare professional if you are uncertain about the best course of action, especially if the pain is severe, you have signs of infection, or the hematoma is large.
What are the potential complications of leaving blood under the nail?
Leaving a large subungual hematoma untreated can lead to several issues:
- Persistent Pain: The pressure from the blood can cause ongoing discomfort.
- Nail Detachment: In severe cases, the blood can cause the nail to separate from the nail bed.
- Infection: A break in the skin under the nail can introduce bacteria, leading to infection.
How long does it take for blood under the nail to heal?
The healing time depends on the size of the hematoma and the chosen treatment method. Small hematomas may resolve within a few weeks with home treatment. Those requiring medical intervention may heal over several months, with the nail often growing out completely.
When should I see a doctor about blood under my nail?
You should seek medical attention if:
- The hematoma is large.
- The pain is severe.
- You notice signs of infection, such as redness, swelling, or pus.
- The nail is significantly detached.
- You have concerns about the injury.
Can I prevent blood from getting under my nails?
While it’s impossible to completely prevent all instances, you can minimize your risk by:
- Wearing protective gear: Use gloves when working with potentially hazardous materials or tools.
- Being careful when handling sharp objects: Pay extra attention when using knives, scissors, or other sharp instruments.
- Protecting your fingers and toes: Wear appropriate footwear and avoid activities that put your nails at risk of injury.
