Nail Subungual Hematoma Treatment
What is Subungual Hematoma?
A subungual hematoma, commonly known as a bruised nail, occurs when an injury to a fingernail or toenail causes bleeding in the tissue directly beneath the nail plate. It is typically caused by direct trauma, such as crushing or slamming the nail, which ruptures the delicate blood vessels underneath. This trapped blood leads to a painful, throbbing pressure, swelling, and a visible dark discoloration (purple, blue, or black) of the nail.
While often very painful initially, these are usually considered minor injuries. For severe pain, a healthcare professional can drain the blood to relieve the pressure. However, if the injury is accompanied by other damage, such as a deep cut or a broken bone, further medical evaluation and treatment will be necessary.
Symptoms of Nail Trauma & Subungual Hematoma
A subungual hematoma typically presents with noticeable symptoms soon after trauma, although some symptoms can develop gradually:Pain Around the Nail
Throbbing or sharp pain beneath the nail is often the first symptom. This pain may worsen as blood continues to pool under the nail plate.
Nail Discoloration
A dark red, purple, or black patch may appear under the nail, caused by trapped blood. The discolouration may spread over time and persist as the nail grows out.
Swelling Nail
Swelling of the nail and surrounding skin is common, particularly after direct trauma. The area may also feel warm or tender to the touch.
Nail Separation (Nail Plate & Bedding)
In some cases, the buildup of pressure can lift the nail plate away from the nail bed. This can lead to partial or complete nail detachment, especially if the hematoma is large or left unmanaged.

Subungual Hematoma Management & Prevention Tips
Here’s how you can manage symptoms and reduce the risk of recurrence:
Apply Ice Immediately
If trauma occurs, apply a cold compress or ice pack to the affected area for 10–15 minutes. This can help reduce initial swelling, limit blood vessel leakage under the nail, and ease pain.
Drain the Hematoma
If the pain is severe and the discoloration covers a significant portion of the nail, medical drainage may be necessary. A medically trained podiatrist can safely relieve the pressure using sterile techniques, reducing discomfort and preventing further nail damage.
Use Pain Relief
Over-the-counter pain relievers such as paracetamol or ibuprofen can help manage discomfort. Avoid anti-inflammatory medication if you have conditions affecting blood clotting unless advised by a healthcare provider.
Monitor for Infection
Watch for signs of infection such as increased redness, warmth, pus, or persistent swelling. These may indicate the need for antibiotics or additional medical intervention.
Wear Protective Gear
When engaging in sports, heavy lifting, or using machinery, wear appropriate footwear or gloves. Protection can shield your nails from high-impact injuries and reduce the risk of subungual hematoma formation.
Cautious with Tools & Equipment
Use caution when handling doors, tools, or weights. Accidents involving fingers and toes commonly occur in domestic or workplace settings and can be avoided with greater awareness and care.
Maintain Proper Foot & Nail Care
Keep nails trimmed and clean to prevent snagging or accidental tearing. Avoid cutting nails too short or damaging the cuticle area, as this can make the nail more vulnerable to trauma and infection.
Use Proper Footwear
Choose footwear with a spacious toe box, proper arch support, and cushioning. Shoes that are too tight or rigid can increase pressure on the toes, especially during walking or exercise, raising the risk of nail injury.
