Black toenails can be a cause for concern, especially when they appear unexpectedly. Not only are they unsightly, but they may also indicate an underlying medical condition that requires attention. In this article, we will delve into the causes and symptoms of black toenails, helping you understand why they occur and what you can do about them.
Causes of Black Toenails
Trauma or Injury
One of the most common reasons behind black toenails is trauma or injury to the toe. This could result from stubbing your toe, dropping a heavy object on it, or wearing tight shoes that exert pressure on the toenail. When the toenail is damaged, blood can accumulate beneath it, causing it to turn black.
Fungal Infection
Another prevalent cause of black toenails is a fungal infection. This type of infection can affect the toenail bed, leading to discoloration and thickening of the nail. Fungal infections are more common in individuals with sweaty feet, those who wear tight shoes, or those who frequent public showers.
Remember, antifungal medication is available to treat fungal infections. However, it’s crucial to consult your doctor for an accurate diagnosis.
The most obvious symptom of a black toenail is, naturally, the discoloration of the nail. Depending on the underlying cause, the nail may appear black, blue, or purple.
Pain or Discomfort
If trauma or injury is responsible for your black toenail, you may experience pain or discomfort in the affected toe. This pain can range from sharp and stabbing to a dull ache.
Thickening of the Nail
If a fungal infection is to blame for your black toenail, you may notice that the nail has become thicker than usual. This can make trimming the nail or wearing shoes uncomfortable.
Separation of the Nail from the Nail Bed
In severe cases, the nail may separate from the nail bed, causing it to loosen or even fall off entirely. This indicates a serious underlying condition that requires medical attention.
Understanding the symptoms associated with black toenails is crucial for obtaining an accurate diagnosis and appropriate treatment. Let us now delve deeper into the symptoms.

Discoloration of the Toenail
As mentioned previously, a noticeable change in nail color is a key symptom of black toenails. Depending on the cause, the nail may appear black, blue, or purple. Discoloration can also signify other nail conditions, such as bruises or blood clots.
Pain or Discomfort
Black toenails resulting from trauma or injury can be painful, particularly if the nail bed is affected. The pain intensity varies, ranging from mild to severe. Over-the-counter pain medication may provide relief in some cases, but severe or persistent pain requires medical attention.
When a black toenail is due to a fungal infection, the nail may become thicker than usual. This can make it challenging to trim the nail or wear shoes comfortably. In some instances, nail deformity or brittleness may occur.
Separation of the Nail from the Nail Bed
In severe cases, the nail may separate from the nail bed, causing it to loosen or fall off completely. This indicates a severe underlying condition necessitating immediate medical attention.
Now, let’s move on to the diagnosis of black toenails.
Diagnosing Black Toenails
If you have a black toenail, it’s crucial to consult a doctor for a proper diagnosis. During the examination, the doctor will carefully inspect the affected toenail and its surroundings for signs of injury, infection, or any other abnormalities. They may inquire about your medical history and the medications you are taking.
In certain cases, the doctor may order an X-ray or MRI imaging test if they suspect a bone fracture or internal injury as the cause of the black toenail. Additionally, if a fungal infection is suspected, the doctor may take a sample of your nail clippings for laboratory analysis. This helps in determining the type of fungus causing the infection and the most effective treatment.
In rare instances, a black toenail could be an indication of skin cancer. If the doctor suspects this, they may perform a biopsy by removing a small tissue sample from the affected area. The sample will then be examined under a microscope to check for the presence of cancerous cells.
