Ingrown toenail

An ingrown toenail develops when the sides of the toenail grow into the surrounding skin.

Symptoms of ingrown toenail

An ingrown toenail often affects the big toe, either on one or both sides. The nail curls and pierces the skin which becomes red, swollen and tender.

Other possible symptoms include:

  • pain if pressure is placed on the toe
  • inflammation of the skin at the end of the toe
  • a build-up of fluid (oedema) in the area surrounding the toe
  • an overgrowth of skin around the affected toe (hypertrophy)
  • bleeding
  • white or yellow pus coming from the affected area

Get help from a pharmacist

If you have an ingrown toenail, you can ask a pharmacist about:

  • treatments to help ease the pain and prevent an infection
  • whether you need to see a GP

Speak to your GP practice if:

  • treating your ingrown toenail at home is not helping
  • your toe is painful and swollen with pus coming out of it
  • you have a very high temperature or you feel hot or shivery
  • you have diabetes and an ingrown toenail – foot problems can be more serious if you have diabetes

Causes of an ingrown toenail

A number of things can cause an ingrown toenail to develop, including:

  • badly cut toenails – cutting your toenails too short, or cutting the edges, will encourage the skin to fold over your nail and the nail to grow into the skin
  • wearing tight-fitting shoes, socks or tights – this places pressure on the skin around your toenail and the skin may be pierced if it’s pressed on to your toenail
  • sweaty feet – if the skin around your toenails is soft, it’s easier for your nail to pierce it and embed itself within it
  • injury – for example, stubbing your toe can sometimes cause an ingrown toenail to develop
  • natural shape of the nail – the sides of curved or fan-shaped toenails are more likely to press into the skin surrounding the nail

fungal nail infection can cause your toenail to thicken or widen.

Treatment for ingrown toenails

Left untreated, an ingrown toenail can become infected. It’s important that you:


  • keep your feet clean by washing them regularly with soap and water
  • change your socks regularly
  • cut your toenails straight across to stop them digging into the surrounding skin
  • gently push the skin away from the nail using a cotton bud (this may be easier after using a small amount of olive oil to soften the skin)
  • wear comfortable shoes that fit properly

Surgery for ingrown toenail

Surgery may be recommended if your toenail doesn’t improve. Depending on the severity of your symptoms, this may involve removing part or all of your toenail.

Partial nail avulsion

Partial nail avulsion removes part of your toenail and is the most common operation for treating ingrown toenails. It’s about 98% effective.

local anaesthetic is used to numb your toe and the edges of your toenail are cut away. A chemical called phenol is applied to the affected area to prevent the nail growing back and becoming ingrown in the future.

A course of antibiotics may be prescribed if your nail is infected, and any pus will be drained away.

Total nail avulsion

Total nail avulsion completely removes your toenail. This may be necessary if your nail is thick and pressing into the skin surrounding your toe. After your toenail has been removed, you’ll have an indentation where your nail used to be. However, it’s perfectly safe for you not to have a toenail.

After surgery

After toenail surgery, your toe will be wrapped in a sterile bandage. This will help stem any bleeding and prevent infection. Rest your foot and keep it raised for 1 to 2 days after the operation.

To help reduce the pain, you may need to take a painkiller like paracetamol. You may also need to wear soft or open-toed shoes for the first few days after surgery.

Preventing ingrown toenails

Taking care of your feet will help prevent foot problems like ingrown toenails. It’s important to cut your toenails properly (straight across, not at an angle or down the edges).

Wash your feet every day, dry them thoroughly and use foot moisturiser. You can also use a foot file or pumice stone to remove hard or dead skin.

Wearing shoes that fit properly will help to ensure your feet remain healthy. You should also change your socks (or tights) every day.

Visit your GP practice or a podiatrist as soon as possible if you develop problems with your feet.
