Brandon podiatrist can help with black toenails and explains the causes

A Brandon Podiatrist talks about the various factors for black toenails and numerous causes. The reason for a black toenail might be benign or quite serious. It is necessary for an individual who develops a black toenail to comprehend a few of the potential causes. When in doubt, it is a great idea have a podiatrist like Dr. Manohar. He can take a look at it, detect the problem, and develop a reliable treatment plan.

Repeated trauma

When an individual uses poorly-fitting shoes, they might be at risk of developing black toenails due to repetitive trauma. Long-lasting pressure on the toes from poorly-fitting shoes can trigger a series of issues, from small blisters to bloody blisters under the nail. In moderate cases, the black toenail will grow out naturally over time without treatment. In serious cases, such as when the nail begins to separate from the nail bed, a person should look for medical treatment.

Blunt force

Sometimes, the injury may be a one-time blunt-force injury, for example, if an individual drops something heavy on their foot or toes. When this occurs, capillaries in the nail bed break, causing blood to pool there. The injured toe will begin to pool blood beneath the skin nearly immediately. The buildup of blood will cause the toe to feel painful and inflamed. Dr. Manohar can treat this condition by draining the blood with a pinprick.

Fungal infections

Fungal infections are another typical issue that can trigger black toenails to form. Generally, a fungal infection triggers a white or yellow-colored staining. Nevertheless, debris can build up near the infection, triggering the nail to appear black. Toenails are especially prone to fungal infections, as socks and shoes can offer a warm and damp breeding ground for a fungus to become developed. Fungal infections can typically be avoided with appropriate foot care.


In unusual cases, a black toenail may be triggered by cancer malignancy. Melanoma is the most aggressive form of skin cancer. Cancer malignancy triggers the skin to develop one or more patches of dark, irregular-looking skin. In some cases, the spot of darkening skin grows beneath the nail bed. Cancer malignancy forms over time, and without other symptoms, so it is often not seen in the early stages, specifically if it starts under the toenail.

Pigmentation changes

People’s complexion can naturally alter gradually. For people with darker skin, a dark patch might appear underneath the toenails. Pigmentation modifications are usually consistent, so if it affects a toe on one foot, it will normally impact the matching toe on the other foot. The fingernails might establish darker spots below them too.

A Brandon Podiatrist can help reveal hidden conditions

There are a few medical conditions that might trigger black toenails. These include the following:

  • diabetes
  • kidney illness
  • cardiovascular disease
  • anemia

In many cases, managing the underlying condition will help the nail to restore its natural color.
