Ingrown Nail

What is an ingrown toenail?

An ingrown toenail is a toenail that has grown into the skin instead of over it. This usually happens to the big toe, but it can also happen to other toes. An ingrown toenail can get infected. It may be painful, red, and swollen, and it may drain pus.

Anyone can get an ingrown toenail, but adults get them more than children do. People who have curved or thick nails are more likely to get an ingrown toenail. This is more common in older adults.

What are the symptoms of an ingrown toenail?

The main symptom of an ingrown toenail is the pain from the nail growing into the skin instead of over it. If the ingrown toenail gets infected, it might be swollen or red, and it might drain pus. The area around the ingrown toenail is often painful.

How is an ingrown toenail diagnosed?

Your doctor will do a physical exam to diagnose an ingrown toenail. He or she will look at your toe where the nail has grown into the skin.

How is an ingrown toenail treated?

You can try the following steps at home to relieve the pain caused by your ingrown toenail and help the nail to grow out naturally:

  • Soak your sore toe in warm water for 15 minutes 2 to 3 times each day.
  • Wedge a small piece of wet cotton, such as part of a cotton ball, under the corner of your ingrown nail. This will help lift the nail off of the skin.
  • Soak your toe and change the piece of cotton each day until the nail grows out and can be trimmed.
  • Do not use a sharp object like manicure scissors to dig under your nail, because the toe might get infected.
  • Do not try to use a needle to drain the pus from your toe. This could make the infection worse.
  • While your ingrown toenail is healing, wear comfortable shoes or sandals that do not press on your toe.

Use these home treatment steps for 3 days. If they do not help, you might need to see your doctor. Be sure to see a doctor if your toe gets infected. Your toe might be infected if it hurts more than it did before you tried the home treatment. Call your doctor if your toe is red, warm, swollen, or drains pus, or if there are red streaks leading from your toe.

Your doctor might give you antibiotics. If your toenail is very ingrown, your doctor might suggest minor surgery to remove all or part of the ingrown nail. He or she may refer you to a podiatrist.

During this surgery, the doctor will numb your toe. Then he or she will cut the edge of the ingrown toenail and pull out the piece of nail. To prevent the nail from growing into the skin again, your doctor might destroy all or part of the nail root. This is called ablation. If your doctor removes all or part of your nail but does not destroy the root, it will begin to grow back within a few months.

After the surgery it is important to take care of your toe so that it can heal. Your doctor will give you specific instructions to follow. He or she may tell you to:

  • Soak your toe in warm water for 15 minutes 2 to 3 times each day.
  • Apply a thin layer of petroleum jelly, such as Vaseline, 2 times each day on the toe where the nail was removed.
  • Wear a bandage on your toe.
  • Wear loose-fitting shoes that don't press on the toe where the nail was removed.
  • Take pain medicine if your toe hurts. Nonsteroidal anti-inflammatory drugs (NSAIDs), including aspirin (such as Bayer), ibuprofen (such as Advil), or naproxen (such as Aleve), might help your toe feel better. Be safe with medicines. Read and follow all instructions on the label.

Teens: How can you care for an ingrown toenail?

  • Trim the nails straight across. Leave the corners a little longer so they do not cut into the skin. To do this when you have an ingrown nail:
    • Soak your foot in warm water for about 15 minutes to soften the nail.
    • Wedge a small piece of wet cotton under the corner of the nail to cushion the nail and lift it slightly. This keeps it from cutting the skin.
    • Repeat daily until the nail has grown out and can be trimmed.
  • Do not use manicure scissors to dig under the ingrown nail. You might stab your toe, which could get infected.
  • Do not trim your toenails too short.
  • Check with your doctor before trimming your own toenails if you have been diagnosed with diabetes or peripheral arterial disease. These conditions increase the risk of an infection, because you may have decreased sensation in your toes and cut yourself without knowing it.
  • Wear roomy, comfortable shoes.
  • If your doctor prescribed antibiotics, take them as directed. Do not stop taking them just because you feel better. You need to take the full course of antibiotics.
