Bruising on finger nails, also known as subungual hematoma, is a common condition characterized by the accumulation of blood under the nail plate. This can be a painful and unsightly experience, often caused by injury or trauma to the finger. However, in some cases, bruising on finger nails can be a symptom of an underlying medical condition. In this article, we will explore the causes of bruising on finger nails, its symptoms, and effective treatment options.
The appearance of a bruise under the nail can be alarming, but it's essential to understand that it's usually not a cause for concern. The nail bed has a rich blood supply, making it prone to bruising. A minor injury, such as closing a door on your finger or stubbing it, can cause blood vessels to rupture, leading to bleeding under the nail.
Causes of Bruising on Finger Nails
There are several reasons why you may experience bruising on your finger nails. Some of the most common causes include:
- Injury or trauma to the finger
- Fungal infections, such as onychomycosis
- Bacterial infections, like paronychia
- Nail biting or picking
- Chemical exposure
- Medical conditions, such as diabetes, poor circulation, or vitamin deficiencies
Injury or Trauma
Injury or trauma to the finger is the most common cause of bruising on finger nails. This can occur due to various reasons, such as:
- Accidental stubbing or bumping
- Sports injuries
- Door or window slamming
- Heavy lifting or manual labor
When the finger is injured, the blood vessels under the nail can rupture, causing blood to leak into the tissue. This leads to swelling, pain, and discoloration of the nail.
Fungal and Bacterial Infections
Fungal and bacterial infections can also cause bruising on finger nails. These infections can lead to inflammation and damage to the nail bed, resulting in bruising.
Fungal infections, such as onychomycosis, can cause:
- Thickening or brittleness of the nail
- Discoloration or staining
- Debris accumulation under the nail
Bacterial infections, like paronychia, can cause:
- Redness and swelling around the nail
- Pus or discharge
- Warmth or tenderness to the touch
