  • Runner’s toe

Individuals who run and wear improperly fitting shoes are also likely to suffer from discoloration of the toenails. This is because such a shoe creates pressure points which cause blood capillaries to be broken off and injuring the surrounding tissue. The solution for a black spot on the toe arising from this condition is to get proper shoes, as well as fitting socks.

The presence of a fungal infection is another cause for a black spot on a toenail. Usually, the first symptoms for a fungal infection are small white specks and this originates from public places when a person has the habit of walking on wet surfaces without their shoes. If the infection is not addressed, the nail becomes thick and starts to feature a brownish color which gradually tends towards black. This is a point of concern especially for individuals suffering from diabetes.

  • Bacterial infection

black spot on the toenailWhile nail polish may cause slight discoloration, bacterial infections will usually result in an alteration in the way the nails look. The culprit responsible for this is a bacterial species known as Pseudomonas aeruginosa, a species that resides on the skin in normal conditions, but if it manages to find a part of the body where the skin is broken, it gets enclosed there leading to an infection. This infection produces a certain odor which the doctor may be able to pick out. This has also been shown to occur in ladies who don artificial nails. The bacteria get trapped between the artificial nail and the real nail where it multiplies and results in the fore mentioned infection. The same happens with individuals who apply nail polish since this creates the same ideal conditions for multiplication of the bacteria.

Whatever the cause of the black spot on the toenail, it is important to see a dermatologist to allay any fears that one’s health could be in danger.
