Finger crush injury resulting in a bruised nail?
Hello, doctor: A few days ago, I injured my finger by pinching it, resulting in bruising under the nail.
After applying some medication, the pain has subsided, but there is some swelling in the tissue behind the nail bed.
When I press it, it hurts a bit and feels elastic, as if there is a plastic sheet inside the tissue.
Is it possible that the nail bed has lifted due to the injury? Currently, besides the slight numbness and swelling in the nail area, it doesn’t hurt unless I press on it.
If I let it fall off on its own, will the nail naturally detach? If the entire nail, including the nail bed, falls off, will it grow back? Or will I need to have it surgically removed? It seems like removing the nail would be very painful...
Thank you.

Hello Kerry: After a finger injury, it is common to develop a hematoma under the nail, leading to significant swelling and pain, especially in the soft tissue near the nail bed and the proximal nail fold.
If the hematoma is small, it will gradually be reabsorbed, resulting in a darker discoloration that becomes less noticeable as the nail grows out.
However, if the hematoma is larger and cannot be reabsorbed, it may cause separation between the nail root, nail bed, and soft tissue, leading to the nail lifting as you described.
If there are no symptoms such as pain or inflammation, you only need to apply warm compresses twice a day and patiently wait for the nail to fall off on its own; a new nail will grow back quickly.
Unless absolutely necessary, there is no need for surgical removal, as nail extraction can be quite painful.
Wishing you a speedy recovery.

More Info
Finger injuries, particularly those involving bruised nails and trauma to the nail bed, can be concerning and often lead to various symptoms that require careful management. Based on your description, it seems that you have experienced a significant injury to your finger, resulting in bruising under the nail and swelling at the base of the nail. Let's address your concerns step by step.
Symptoms and Healing Process
1. Bruising and Swelling: The bruising you see under the nail is likely due to bleeding from damaged blood vessels, which is common in nail injuries. The swelling at the base of the nail, along with the tenderness you feel when pressing on it, suggests that there may be some inflammation or fluid accumulation in the area. This can occur as part of the body's natural healing response.
2. Nail Bed Trauma: The sensation of a "plastic sheet" feeling under the skin could indicate that the nail bed has been affected. If the nail bed is damaged, it can lead to changes in how the nail grows back. In some cases, the nail may lift or separate from the nail bed, which can be painful and may require medical intervention.
3. Nail Loss and Regrowth: If the nail is significantly damaged, there is a possibility that it may eventually fall off. However, if the nail bed is intact and the injury is not severe, the nail may remain attached and grow back normally. Nails typically take several months to fully regrow, and the new nail may initially appear different in texture or color.
Management and Treatment
1. Observation: If the pain is minimal and you are not experiencing severe symptoms (like excessive swelling, redness, or pus), you may choose to observe the injury for a few days. It's important to keep the area clean and dry. Avoid any activities that may further injure the finger.
2. Pain Management: Over-the-counter pain relievers such as ibuprofen or acetaminophen can help manage any discomfort. If the pain worsens or if you notice increased swelling or discoloration, it would be wise to seek medical attention.
3. When to Seek Medical Help: If the nail appears to be lifting significantly or if you experience severe pain, it is advisable to consult a healthcare professional. They may need to assess the injury more thoroughly and determine whether the nail needs to be removed. While nail removal can be painful, it is sometimes necessary to prevent further complications, especially if there is an underlying infection or if the nail is at risk of becoming ingrown.
4. Preventing Infection: Keep the area clean and monitor for signs of infection, such as increased redness, warmth, or discharge. If you notice any of these symptoms, seek medical attention promptly.
5. Nail Care Post-Injury: Once the initial healing has occurred, you may want to consider using a protective bandage to shield the nail as it grows back. Additionally, maintaining a balanced diet rich in vitamins and minerals can support nail health and regrowth.
Conclusion
In summary, while your symptoms may be concerning, many finger injuries heal well with appropriate care. It is essential to monitor your symptoms closely and seek medical advice if you have any doubts about the healing process or if your symptoms worsen. Remember that patience is key, as nail regrowth can take time, and ensuring proper care will facilitate a smoother recovery.

Bruising at the site of reattached fingers is a temporary phenomenon. If there is no impact on function and no further deterioration, there is no need for concern.
