Fingernail blood under the nail, also known as subungual hematoma, is a common condition that can be caused by a variety of factors. It occurs when blood accumulates under the nail plate, causing pain, swelling, and discoloration. While it may be alarming, subungual hematoma is usually not a cause for concern and can be treated with simple home remedies. However, in some cases, it can be a sign of an underlying medical condition that requires attention.
The causes of fingernail blood under the nail can be broadly categorized into two groups: trauma and medical conditions. Trauma to the nail, such as slamming it in a door or dropping something on it, is the most common cause of subungual hematoma. This type of injury can cause blood vessels under the nail to rupture, leading to bleeding and swelling. Medical conditions, such as poor circulation, diabetes, and certain nutritional deficiencies, can also cause subungual hematoma.
Trauma-Related Causes of Fingernail Blood Under the Nail
Trauma to the nail is the most common cause of subungual hematoma. This type of injury can occur due to a variety of reasons, including:
- Accidental injury, such as slamming the finger in a door or dropping something on it
- Sports-related injuries, such as jamming a finger while playing basketball or soccer
- Workplace injuries, such as using a hammer or other tool that can cause nail trauma
The Role of Poor Circulation in Subungual Hematoma
Poor circulation is a medical condition that can cause subungual hematoma. When blood flow to the fingers and toes is reduced, it can lead to a range of symptoms, including pain, swelling, and discoloration. Poor circulation can be caused by a variety of factors, including:
| Cause | Description |
|---|---|
| Atherosclerosis | A buildup of plaque in the arteries that can reduce blood flow to the fingers and toes |
| Smoking | Smoking can damage blood vessels and reduce blood flow to the fingers and toes |
| Diabetes | Diabetes can damage blood vessels and reduce blood flow to the fingers and toes |
Nutritional Deficiencies and Subungual Hematoma
Nutritional deficiencies, such as a lack of vitamin B12 or iron, can also cause subungual hematoma. These deficiencies can lead to a range of symptoms, including fatigue, weakness, and discoloration of the skin and nails.
A diet rich in essential nutrients, such as fruits, vegetables, and whole grains, can help prevent nutritional deficiencies. In some cases, supplements may be necessary to address underlying deficiencies.
The Importance of Proper Nail Care
Proper nail care is essential for preventing subungual hematoma. This includes:
- Keeping the nails clean and dry
- Trimming the nails straight across
- Avoiding sharing personal care items, such as nail clippers
