Ingrown nail

Sometimes a nail grows into the skin.

This can make your toe hurt. It might look red and puffy.

Tight shoes can cause this. They press on your toes. This makes the nail dig in.

Cutting your nails wrong can cause it too. You should cut them straight across. Do not cut them in a curve.

It often happens to the big toe.

It can also happen to your hands.

Doctors can help fix a sore nail. You can keep your toes happy by being careful.

An ingrown nail happens when a nail grows into the skin.

This often happens to toenails. It can be very painful. You might see redness or swelling. Sometimes, fluid or blood can come from the area. This can lead to an infection.

Many things can cause this. Tight shoes are a big reason. They press on the toes. This pressure pushes the skin against the nail.

You can also cause it by cutting nails wrong. If you cut them in a curve or too short, the nail may grow into the flesh. An injury to the toe can also cause it.

There are ways to help. For small cases, people use warm water soaks. Some use nail braces. These are tools that gently lift the edges of the nail. They help the nail grow in a flatter shape.

This can take about 18 months. If the problem is bad, a podiatrist can help. A podiatrist is a doctor for feet. They may perform a wedge resection. This is a way to remove the part of the nail that is digging in.

An ingrown nail is a common nail problem. Scientists call this condition onychocryptosis. The name comes from Ancient Greek words. One part means "nail" and the other means "hidden." This happens when a nail grows into the skin. It usually cuts into the sides of the nail bed. This can be very painful for many people. It most often happens to toenails rather than fingernails.

There are a few ways this happens. A true ingrown nail occurs when a sliver of nail pierces the flesh. Sometimes, overgrown skin can also cause the problem. Pressure from shoes is a very big cause. Tight shoes or tight stockings push the skin against the nail. This can cause the skin to bulge up. The pressure can lead to swelling and redness. It can even cause an infection with pus or blood.

How you cut your nails matters a lot. If you cut them too short, they may bend. You should always cut your nails straight across. If you use scissors at a bad angle, the nail may grow upward. This happens if the bottom blade is closer to the toe. The nail can also grow incorrectly if you cut it in a curve. Even an injury can change how a nail grows. Dropping something on your toe might make the nail grow crooked.

There are many ways to treat an ingrown nail. For mild cases, people use warm water and salt soaks. Some people use nail braces to help.

An adhesive brace is a thin strip glued to the top. A hooked brace uses dental wire to pull the edges up. These braces help the nail grow in a flatter shape. This process can take about 18 months to finish. It takes one full nail growth to see the change.

A podiatrist is a doctor who specializes in feet. They can help with more serious cases. One method is called a wedge resection. This is when a doctor removes the part of the nail that is digging in. If the problem keeps coming back, they might do a matrixectomy. This is a way to destroy the sides of the nail. This helps stop the nail from growing inward again. Surgery is often better at preventing the problem from returning.

An ingrown nail, or onychocryptosis, is a common condition involving the nails.

The term comes from Ancient Greek, where "onux" means nail and "kruptos" means hidden. This condition occurs when a nail grows into the sides of the paronychium, which is the skin surrounding the nail, or the nail bed. While it can affect fingernails, it is most frequently seen in toenails.

It is often a very painful experience for the person affected.

There is a distinction between different types of nail issues. A true ingrown nail involves an actual sliver of the nail penetrating the flesh. However, the condition can also be caused by overgrown skin. In some cases, microbial inflammation of the paronychium leads to a granuloma, which is a mass of tissue that buries the nail. It is important not to confuse onychocryptosis with other growth patterns. These include convex nails, involuted nails, or pincer nails. It also differs from having calluses, corns, or debris in the nail sulci, which are the grooves at the sides of the nail.

Many factors can trigger the development of an ingrown nail. Footwear is a primary contributor, especially ill-fitting shoes with a narrow toe box. Tight stockings can also apply unwanted pressure to the sides of the foot. A damp environment inside a shoe can soften the nail plate. This softening can lead to swelling in the epidermal keratin, which may permanently increase the convex arch of the nail. Other causes include genetics, disease, or physical trauma. For example, dropping a heavy object on a toe or stubbing it can cause the nail to grow irregularly.

How a person manages their nail care can directly impact their health. Cutting nails too short or rounding the edges can cause them to dig into the skin. The angle of the cutting tool, such as scissors, is also critical. If the lower blade is closer to the toe than the upper blade, the nail may grow upward from its base. Conversely, if the angle is different, it may grow downward. This creates a warp that moves toward the end of the nail as it grows. To prevent this, nails should be cut straight across and should not be shorter than the surrounding flesh.

Symptoms of onychocryptosis can range from mild to severe. Common signs include pain along the margins of the nail caused by hypergranulation. This pain often worsens when wearing tight shoes or when any pressure is applied. In some cases, even the weight of bedsheets can cause sensitivity. If the condition is not treated early, it can lead to infection. Signs of infection include redness, swelling at the base of the nail, and the drainage of pus or blood-tinged fluid.

Treatment options depend heavily on the severity of the case. Mild to moderate cases might be managed with conservative methods. These include soaking the foot in warm water with Epsom salt, using antibacterial ointment, or using dental floss. Another option is nail bracing, which is less invasive than surgery.

There are adhesive braces, which are composite strips glued to the nail, and hooked braces, which use dental wire to lift the nail edges. Bracing aims to retrain the nail to grow in a flatter shape. This process typically requires one full nail growth cycle, which lasts about 18 months.

For more serious or recurring cases, a podiatrist may perform surgery. A podiatrist is a specialist who focuses on the feet and ankles. One common procedure is a wedge resection, where the offending part of the nail plate is removed.

If the nail continues to grow inward despite this, a doctor might perform a matrixectomy. This involves the excision or chemical destruction of the sides of the nail to prevent regrowth. Surgical treatments are generally more effective at preventing the condition from returning than non-surgical methods.
