Black nails are usually caused by trauma and sports-related injuries, but they can also be caused by fungal infections, bacterial infections, chronic ingrown nails, and systemic health conditions like diabetes, kidney disease, anemia, or heart disease. In most cases, black nails will grow out and the discoloration will disappear. However, if the black nail is caused by an underlying condition, such as melanoma, it may require treatment. If the black nail is not causing any pain and less than half of the nail is affected, there is usually no need for treatment. However, if the discoloration covers more than half of the nail or if there are signs of infection, it is important to see a healthcare provider.

What You'll Learn
Black nails are often caused by trauma or injury
Black nails are usually caused by trauma or injury. This could be a stubbed toe, a dropped object, or an injury from running or sports. In such cases, the discoloured part of the nail will disappear as the nail grows out. This typically takes about four to six months, but it can take up to nine months. In some cases, the nail may fall off and regrow in about six months, though there is a possibility that the new nail may not look normal.
If the black nail is not causing pain and less than half of the nail is discoloured, there is no need for treatment. However, if more than half of the nail is affected, or if the injury is severe, a doctor may recommend removing the nail. They may also drain the blood by making small holes in the nail to relieve the pressure. This procedure must be done within a few days of the injury.
If the black nail is not due to trauma or injury, it could be caused by other factors such as fungal infections, bacterial infections, chronic ingrown nails, or underlying health conditions like diabetes, kidney disease, anaemia, or heart disease. Melanoma can also cause black nails, and it is important to rule out this possibility.

Melanoma can cause toenails to darken
A black nail will often grow out and is usually not a cause for concern. In many cases, it will clear up by itself over time. However, it is important to be vigilant about monitoring any spots on your nails and noting any changes.
The cause of subungual melanoma is not fully understood, but it is believed that certain factors can increase the risk of developing it. These factors include having darker skin, a family or personal history of melanoma, and being older than 50. Additionally, severe injury, damage, or trauma to the nail may also be risk factors. It is important to see a doctor if you notice any nail changes, such as discoloration, changes in shape or thickness, or any other unusual damage. Early detection of subungual melanoma is crucial for a positive prognosis and successful treatment.
While a black nail is often harmless and will grow out, it is important to be vigilant and seek medical advice if necessary. If left untreated, subungual melanoma can be deadly. To prevent melanoma, it is recommended to reduce direct sun exposure and wear sunscreen. Additionally, wearing proper-fitting shoes during exercise can help prevent toenail trauma, which is a common cause of black toenails.

Fungal infections can cause black nails
A black nail will often grow out and clear up by itself over time. In mild cases, no treatment is needed. However, fungal infections can cause black nails and may spread to other parts of the foot and body if left untreated.
Fungal nail infections, or onychomycosis, are caused by microorganisms that invade the toenail or fingernail. Fungi are tiny organisms that thrive in dark, warm, and moist places, making toenails more susceptible to infection than fingernails. The infection usually starts at the edge of the nail and spreads to the rest of the nail, causing the nail to become discoloured, thickened, distorted, brittle, or crumbly. It may also cause the skin around the nail to become painful and swollen.
Fungal nail infections are relatively common and can be treated at home with over-the-counter ointments, creams, and polishes. However, severe cases may require prescription antifungal treatments, such as oral medication or topical creams. It's important to treat fungal nail infections promptly and consistently to prevent the infection from returning.
To prevent fungal nail infections, it's recommended to keep your nails clean and dry and to avoid walking barefoot in places like communal showers, pools, and gyms, where fungi can spread easily. Additionally, proper-fitting shoes can help prevent toenail trauma, which is another common cause of black nails.

Ill-fitting footwear can cause black nails
In most cases, a black nail will grow out and heal with time. However, if the discolouration is due to ill-fitting footwear, it is essential to address the root cause to prevent further issues.
To prevent black nails caused by ill-fitting footwear, it is recommended to wear properly fitting shoes, especially during exercise or running. Keeping toenails short, sizing up a half size in shoes, or wearing thinner socks can also help alleviate pressure on the toes and reduce the risk of developing black nails.
While mild cases of black nails may not require any treatment, it is important to monitor for any signs of infection or underlying conditions. If the black nail is accompanied by pain, it is advisable to consult a doctor, as they can drain the blood from under the nail to relieve pressure and prevent further complications.
Additionally, it is important to be mindful of potential underlying conditions that may contribute to black nails. For example, fungal infections, melanoma, diabetes, or other health issues can cause discolouration. Therefore, if the black nail persists or is accompanied by other symptoms, seeking medical advice is recommended to rule out any serious conditions and receive appropriate treatment.

Black nails can be symptomless and resolve on their own
Black nails are usually caused by trauma or injury, such as stubbing your toe or dropping something on it, and are often painless. In such cases, the discoloured part of the nail will disappear as the nail grows out. This process typically takes about four to six months, although it can take up to nine months for the nail to fully regrow.
If the black nail is not causing you pain and less than half of the nail is discoloured, there is no need for treatment. The nail will grow out, and the discolouration will no longer be present. However, if the discolouration covers more than half of the nail, or if the nail is beginning to separate, it is recommended to consult a healthcare provider. They may suggest removing the nail.
In rare cases, black nails can be a symptom of an underlying condition, such as melanoma, fungal or bacterial infections, chronic ingrown nails, or systemic health conditions like diabetes, kidney disease, anaemia, or heart disease. Melanoma can cause the skin to develop dark, irregular patches, and these patches can sometimes grow beneath the nail bed. As melanoma develops slowly, it often goes unnoticed in its early stages, especially if it starts under the toenail. Therefore, it is important to see a doctor if you experience any unexplained black spots on your nails that do not go away as the nail grows out.
Fungal infections of the toes are usually treatable at home with over-the-counter ointments, creams, and polishes. However, severe cases may require prescription antifungal treatments. It is important to treat fungal infections promptly to prevent them from spreading to other parts of the foot and body.
