Black or darkened toenails are essentially bruised nails and can result from a variety injuries or problems. Darkened nails may occur as a result of the toe hitting the end or the top of the shoe toe area. Sometimes, the bruise can lead to a fungal nail infection. Treatment may include trimming the nail back and applying a topical antifungal medication. If the skin under the nail is ulcerated, a topical antibiotic ointment should be applied. 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. Ingrown toenails, also known as onychocryptosis, is usually caused by trimming toenails too short, particularly on the sides of the big toes. They may also be caused by shoe pressure (from shoes that are too tight or short), injury, fungus infection, heredity, or poor foot structure. Ingrown toenails occur when the corners or sides of the toenail dig into the skin, often causing infection. A common ailment, ingrown toenails can be painful. Ingrown toenails start out hard, swollen, and tender. Left untreated, they may become sore, red, and infected and the skin may start to grow over the ingrown toenail. In most cases, treating ingrown toenails is simple: soak the foot in warm, soapy water several times each day. Avoid wearing tight shoes or socks. Antibiotics are sometimes prescribed if an infection is present. Note: Please consult your physician before taking any medications. In severe cases, if an acute infection occurs, surgical removal of part of the ingrown toenail may be needed. Known as partial nail plate avulsion, the procedure involves injecting the toe with an anesthetic and cutting out the ingrown part of the toenail. Ingrown toenails can be prevented by:
- Trimming toenails straight across with no rounded corners.
- Ensuring that shoes and socks are not too tight.
- Keeping feet clean at all times.Many people don't realize they have a fungal nail problem and, therefore, don't seek treatment. Yet, fungal toenail infections are a common foot health problem and can persist for years without ever causing pain. The disease, characterized by a change in a toenail's color, is often considered nothing more than a mere blemish. Left untreated, however, it can present serious problems. Also referred to as onychomycosis, fungal nails are infections underneath the surface of the nail, which may also penetrate the nail. Fungal nail infections are often accompanied by a secondary bacterial and/or yeast infection in or about the nail plate, which ultimately can lead to difficulty and pain when walking or running. Symptoms may include discoloration, brittleness, loosening, thickening, or crumbling of the nail. A group of fungi, called dermophytes, easily attack the nail and thrive on keratin, the nail's protein substance. In some cases, when these tiny organisms take hold, the nail may become thicker, yellowish-brown, or darker in color, and foul smelling. Debris may collect beneath the nail plate, white marks frequently appear on the nail plate, and the infection is capable of spreading to other toenails, the skin, or even the fingernails. Nail bed injury may make the nail more susceptible to all types of infection, including fungal infection. Those who suffer chronic diseases, such as diabetes, circulatory problems, or immune-deficiency conditions, are especially prone to fungal nails. Other contributory factors may be a history of Athlete's Foot or excessive perspiration. You can prevent fungal nail infections by taking these simple precautions:
- Exercise proper hygiene and regularly inspect your feet and toes.
- Keep your feet clean and dry.
- Wear shower shoes in public facilities whenever possible.
- Clip nails straight across so that the nail does not extend beyond the tip of the toe.
- Use a quality foot powder (talcum, not cornstarch) in conjunction with shoes that fit well and are made of materials that breathe.
- Avoid wearing excessively tight hosiery, which promotes moisture. Socks made of synthetic fiber tend to "wick" away moisture faster than cotton or wool socks, especially for those with more active lifestyles.
- Disinfect home pedicure tools and don't apply polish to nails suspected of infection.
