Black or darkened toenails are essentially bruised nails, resulting from a variety of injuries or issues. Darkened nails may occur as a result of the toe hitting the end or the top of the shoe toe area. The bruise can lead to a fungal nail infection.

Treatment may include trimming the nail back and applying a topical antifungal medication, or if the skin under the nail is tender and bruised, a topical antibiotic ointment should be applied.

Please contact our office for evaluation if you are a Diabetic patient experiencing change in toenail color. The pressure causing the bruised nail may lead to a small sore under the toenail, which can lead to infection.
