Trauma to the nail bed
Red spots on nails are usually harmless and will resolve on their own. However, they can sometimes be a sign of an underlying condition that requires medical attention.

Melanoma
Red spots on nails are often harmless and can be caused by trauma to the nail bed, such as hitting your finger or toe, which can cause bleeding under the nail. However, in rare cases, they can be a sign of an underlying health condition, such as melanoma. Melanoma is a type of skin cancer that can cause red or black spots on the nails. If you notice any persistent spots, changes in nail shape or texture, or if the spots are increasing in size, it is important to seek medical attention.
While melanoma most commonly affects the skin, it can also develop in other parts of the body, including the nails. When melanoma occurs in the nails, it is known as subungual melanoma. This type of melanoma can be difficult to detect, as the early signs and symptoms may be subtle and easily overlooked. However, it is important to be aware of any changes in the appearance of your nails, as early detection and treatment of melanoma can significantly improve outcomes.
The symptoms of subungual melanoma can include changes in nail colour, such as the appearance of red or black spots or streaks. These spots may resemble a splinter under the nail and can be caused by bleeding under the nail due to injury or trauma. Other symptoms may include changes in nail shape or texture, such as thickening or brittleness. In some cases, subungual melanoma may also cause pain or discomfort in the affected nail.
If you notice any of the symptoms mentioned above, it is important to consult a healthcare professional as soon as possible. They will be able to examine your nails and determine if further testing or treatment is necessary. While the presence of red spots on your nails may be harmless, it is always better to err on the side of caution when it comes to your health.

Endocarditis
Red spots on your nails are often harmless and can be caused by trauma or injury to the nail bed, resulting in bleeding underneath the nail. However, in rare cases, they can be a sign of an underlying health condition. One such condition is endocarditis, an infection of the heart's inner lining or valves. Endocarditis can cause splinter haemorrhages, which appear as red spots resembling wood splinters under the nail. While these spots may resolve on their own, it is important to consult a healthcare professional if you have any concerns or notice any changes in their appearance.
The treatment for endocarditis typically involves a prolonged course of intravenous antibiotics to eradicate the infection. In some cases, surgery may be required to repair damaged heart valves or to remove infected tissue. Early diagnosis and treatment are crucial to prevent complications and improve outcomes.
To prevent endocarditis, it is essential to maintain good oral hygiene and seek prompt treatment for dental infections. Individuals at high risk may also require antibiotic prophylaxis before certain dental or surgical procedures. Additionally, practising good hygiene and avoiding exposure to infectious agents can help reduce the risk of contracting endocarditis.

Splinter hemorrhages
Red spots on nails are often harmless and can be caused by injury to the nail bed, such as hitting your finger or toe, which can cause bleeding under the nail. However, in rare cases, they can be a sign of an underlying health issue.
Splinter haemorrhages
Splinter haemorrhages are small, red or black spots on the nails that resemble a wood splinter. They are caused by bleeding under the nail, which can occur after injury or trauma to a fingernail or toenail. This can happen when you bump or injure your toe or finger, damaging the blood vessels along the nail bed and causing bleeding.
While splinter haemorrhages are often harmless, they can sometimes be a sign of a more serious health issue, such as endocarditis or skin cancer. If you notice any red or black spots on your nails that do not go away or are accompanied by other symptoms, it is important to consult a healthcare professional.
