Melanonychia: a brown or black colour in your nail that can be harmless or potentially fatal
Melanonychia is a brown or black colour in your nail. It can affect one nail, a few nails, or all of your nails. It can be harmless or potentially fatal. Melanonychia can look different depending on what caused it. It can appear as longitudinal melanonychia or melanonychia striata, which appears as brown, black or grey bands that run from the nail bed to the tip of the nail. It can also appear as diffuse or total melanonychia.
Melanonychia can be caused by injury or trauma to the nail. Bumping your toe or finger can damage blood vessels along the nail bed and cause bleeding under the nail. This is known as a splinter haemorrhage. In some cases, a splinter haemorrhage can be a symptom of cancer called subungual melanoma. If your doctor suspects a malignancy, they will recommend a biopsy to determine if the dark spot is cancerous or benign.
It is important to understand that these spots can have various causes, some harmless and others requiring medical attention. You should always have a doctor examine any dark streaks in your nails.

Beau's lines: thick lines that create a horizontal stripe on the nail, which are usually not harmful but can be a symptom of cancer
Beau's lines are thick lines that create a horizontal stripe on the nail. They are usually not harmful but can be a symptom of cancer. Beau's lines are typically harmless and will resolve on their own. However, they can sometimes be a sign of an underlying condition that requires medical attention.
Beau's lines are often a result of injury or trauma to a fingernail or toenail. Bumping a toe or injuring a finger can damage blood vessels along the nail bed, causing bleeding under the nail. This type of injury is known as a splinter haemorrhage. In some cases, splinter haemorrhages can be a symptom of endocarditis, an infection of the heart valves and lining.
If you notice Beau's lines on your nails, it is important to consult a doctor to determine the underlying cause. Your doctor may recommend a biopsy to determine if the condition is cancerous or benign. Treatment for splinter haemorrhages will vary depending on the underlying cause. In some cases, no treatment is needed, and the condition will resolve on its own.
While Beau's lines are typically harmless, they can be a cause for concern in certain cases. If you notice any changes in your nails, such as dark spots or thick horizontal stripes, it is always best to consult a medical professional for a proper diagnosis and treatment plan.

Trauma: injury to the nail bed, such as hitting your finger, can cause bleeding under the nail
Dark spots under the fingernails can be caused by trauma to the nail bed. This can occur when you hit your finger or toe, damaging the blood vessels along the nail bed and causing bleeding under the nail. This type of injury is known as a splinter hemorrhage and can result in red or black spots. While these spots are often harmless and will resolve on their own, they can sometimes be a sign of a more serious underlying condition, such as endocarditis or subungual melanoma, a type of skin cancer. Therefore, it is important to have any dark spots on your nails examined by a doctor to rule out any potential health concerns.
Trauma to the nail bed can occur in various ways, such as accidentally hitting your finger or toe against a hard surface or object. This impact can cause damage to the delicate blood vessels and tissues under the nail, resulting in bleeding and the formation of dark spots. The severity of the injury can vary, and in some cases, the nail may become detached from the nail bed.
The appearance of dark spots under the fingernails due to trauma can vary in size, shape, and colour. They may appear as small, isolated spots or larger areas of discolouration. The colour can range from deep red to black, depending on the extent of the bleeding and the time since the injury occurred. Fresh blood may appear bright red, while older blood can turn darker and appear brownish or black.
The treatment for dark spots under the fingernails caused by trauma will depend on the severity of the injury. In most cases, the body will reabsorb the blood, and the dark spots will gradually fade and grow out with the nail. However, if the injury is more severe or there is significant pain or swelling, medical attention may be required. Your doctor may recommend a biopsy or other tests to rule out any underlying conditions and determine the best course of treatment.
