Black or darkened toenails are essentially bruised nails and can result from a bleeding beneath the nail plate. Darkened nails may occur as a result of an injury, the toe hitting the end or the top of the shoe toe area or a varity of other injuries.
Treatment may include trimming the nail, removal of the nail to release the pressure beneath the nail. If the nail bed under the nail is damaged repair may be needed.
Diabetic patients should contact our office for evaluation if they experience any change in the color of toenails The pressure causing the bruised nail may lead to a small sore under the toenail, which can lead to infection.
