Onychocryptosis, commonly known as ingrown nails (unguis incarnatus), is a common form of nail disease. It's is a painful condition in which the nail grows or cuts into one or both sides of the nail bed. While ingrown nails can occur in both the nails of the hand and feet, they occur most commonly with toenails.

While many things can cause ingrown nails, the most common causes are improperly fitted shoes and nails that are improperly trimmed. Shoes or stockings that are too tight press on the sides of the nail, causing it to curl and dig into the skin.Nails that are cut too short, rounded off at the tip, or are peeled off at the edges versus being cut straight across are more likely to become ingrown as well. Other causes include an abnormally shaped nail bed, trauma to the nail plate or toe and other nail deformities. Proneness to nail deformities that cause ingrown nails can also be genetic.

Symptoms of an ingrown nail include pain along the margins of the nail, worsening of pain when wearing shoes or other tight articles, and sensitivity to pressure of any kind, even that of light bedding. By the very nature of the condition, ingrown nails become easily infected unless special care is taken to treat the condition early on and keep the area as clean as possible. Signs of infection include redness and swelling of the area around the nail, drainage of pus and/or a watery discharge tinged with blood.

Treatment of ingrown nails ranges from soaking the afflicted area to surgery. In mild cases, doctors recommend daily soaking of the foot or hand in a mixture of warm water and Epsom salts and applying over-the-counter antibiotics while allowing the nail to grow out so it may be trimmed properly. Another remedy is to file the top of the nail flat. This will cause the nail to contract and pull the ingrown sides up.

More severe cases, such as when the area around the nail becomes infected or the nail will not grow back properly, must be treated by a professional. In these cases, the digit is first injected with a common local anesthetic. After the area is numb, the physician will cut away the nail along the edge that is growing into the skin and pull out the piece of nail. In some cases they may also surgically drain the infection or use a chemical on the skin to prevent nail re-growth. The entire procedure may be performed in a standard doctor's office and takes approximately thirty to forty-five minutes depending on the extent of the problem. The patient is allowed to go home immediately and the recovery time is anywhere from a few days to a week barring any complications such as infection. As a follow-up, a physician may prescribe an oral or topical antibiotic or a special soak to be used for approximately a week after the surgery.

A pedicure is a way to improve the appearance of the feet, and their nails. Its basically like a manicure in the hand. The word pedicure comes from the Latin words pes, which means foot, and cura, which means care. It also means the care of the feet and toenails. A pedicure can be helpful because it can prevent from nail diseases and disorders.

A manicure is a cosmetic beauty treatment for fingernails and hands. A manicure can treat just the hands, just the nails, or both. A standard manicure usually includes filing and shaping of the nails and the application of polish. Some specialty manicures, such as the French Manicure, may also be offered. Treatments for hands usually include soaking in a softening substance and application of hand lotion. A similar treatment performed on the feet is a pedicure. The word "manicure" comes from the Latin word manus, meaning "hand," and cura meaning "cure".

Various services for nails can be provided, such as the application of artificial nails such as nail tips, acrylics and artificial nail gels. A manicurist can also apply treatments to real nails, such as filing, polishing, and painting. Fancier manicures include painting pictures or designs on the nails or applying small decals or imitation jewels.

In many areas, manicurists are regulated and must be licensed. Because the skin is being manipulated and sometimes trimmed, and because there is a risk of infection when tools are used on multiple people, proper sanitation is difficult.
