Black Toenails

Black toenails can result from a variety of things. Athletes will often encounter a problem with their toenails turning dark. Darkened nails often occur from the toe hitting the end or the top of the shoe toe area. The darkened nail is essentially a bruised nail. Sometimes, the bruise can lead to a fungal nail infection. If you are a diabetic, any change in the color of your toenail should be evaluated. Contact our office to set up an appointment. The pressure, which caused the bruising of the nail, can cause a small sore under the toenail, and the sore can become infected.

Treatment may include trimming the loose nail back and applying a topical anti-fungal medication. If the skin under the nail is ulcerated, a topical antibiotic ointment should be applied. Patients with diabetes should not treat this condition themselves and should contact our office.
