How To Treat Infected Ingrown Toenail? Guide

An infected ingrown toenail happens when the corner or side of a toenail grows into the skin, and bacteria get inside. The area becomes red, swollen, warm to the touch, and may ooze pus. You can treat most mild infections at home with warm soaks and proper care, but if the infection spreads past the toe or you have diabetes, you need a doctor right away. The key steps are to reduce swelling, keep the area clean, and know when to seek medical help.

What Does an Infected Ingrown Toenail Look Like?

An infected ingrown toenail is different from one that is just painful. The skin next to the nail will be red and swollen. It may feel warm or hot when you touch it. You might see yellow or green pus if you press gently on the area.

In more serious cases, the infection can spread. Red streaks moving up the foot or leg are a sign of a worsening infection. The toe may also start to smell. The CDC reports that people with diabetes or poor circulation are at higher risk for complications from these infections. If you notice any of these signs, do not wait. See a healthcare provider.

How To Treat Infected Ingrown Toenail at Home Safely

For a mild infection with no red streaks and no fever, home care can work. Soak the foot in warm water with Epsom salt for 15 to 20 minutes, three to four times a day. This softens the skin and helps drain any pus naturally.

After soaking, dry the foot completely. Apply an over-the-counter antibiotic ointment like bacitracin or neomycin to the area. Cover it with a clean bandage. Do not try to cut the nail yourself or dig into the skin. This can push bacteria deeper and make the infection worse.

Wear open-toed shoes or sandals if possible. Tight shoes put pressure on the toe and slow healing. Keep the foot elevated when sitting to reduce swelling. Research published in the Journal of the American Podiatric Medical Association found that proper home care resolves most mild ingrown toenail infections within a week.

When Does Home Care Stop Working?

Home care has limits. If the toe does not improve after three days of soaks and ointment, the infection may need medical treatment. Signs that home care is not enough include increasing pain, more swelling, or pus that does not stop draining.

People with diabetes, peripheral artery disease, or a weakened immune system should never rely on home care alone. The American Diabetes Association advises that any foot infection in a person with diabetes requires immediate medical evaluation. What looks like a minor infection can quickly become a serious problem.

If you develop a fever or chills, the infection has likely entered the bloodstream. This is a medical emergency. Go to an urgent care center or emergency room.

What Medical Treatments Are Available?

Doctors have several options depending on how bad the infection is. For a mild to moderate infection, they may prescribe oral antibiotics. Common choices include cephalexin or clindamycin. These target the bacteria most often found in skin infections.

If there is a pocket of pus, the doctor may need to drain it. This is called incision and drainage. They numb the toe, make a small cut, and let the pus out. The relief is often immediate.

For ingrown toenails that keep getting infected, a minor procedure called a partial nail avulsion may be recommended. The doctor removes the edge of the nail that is growing into the skin. They may also apply a chemical called phenol to prevent that part of the nail from growing back. Research in the Cochrane Database of Systematic Reviews found that this procedure has a success rate above 90% for preventing recurrence.

Common Mistakes People Make When Treating Ingrown Toenails

Many people try to fix an ingrown toenail by cutting a V-shape into the nail. This is a myth. It does not help the nail grow straight. It just creates a sharp edge that can dig in further.

Another common error is using a cotton ball or dental floss to lift the nail. While some sources suggest this for non-infected nails, it is risky once infection is present. You can push bacteria deeper into the tissue. The American Academy of Dermatology advises against any at-home nail lifting if signs of infection are present.

Do not use sharp tools like nail clippers, scissors, or razor blades to dig out the nail. This almost always makes the infection worse. Podiatrists see people daily who tried to “dig it out” at home and ended up with a much worse infection.

Some people also apply hydrogen peroxide directly to the wound. This can damage healthy tissue and slow healing. Stick to warm water soaks and antibiotic ointment.

How To Prevent Infected Ingrown Toenails From Coming Back

Prevention is straightforward once you know what causes the problem. Cut your toenails straight across. Do not round the corners. The nail should be level with the tip of the toe, not shorter. The American Orthopaedic Foot & Ankle Society recommends this as the single most effective prevention method.

Wear shoes that fit properly. Shoes that are too tight in the toe box press the nail into the skin. Shoes that are too loose let the foot slide forward and jam the toes. Both can cause ingrown nails.

Avoid repeated trauma to the toes. People who run long distances or play soccer are more likely to develop ingrown toenails. If you are active, keep toenails trimmed straight and wear moisture-wicking socks to reduce friction.

Keep feet clean and dry. Bacteria grow in warm, damp environments. Change socks daily and dry between the toes after showering. This reduces the chance of a minor ingrown nail turning into an infection.
