An ingrown toenail happens when the edge of the nail presses or grows into the skin beside it. It's usually the big toe, and it can be surprisingly painful. Here's what you can do, and when it's time to get it looked at.
Common causes
- Cutting nails too short or down into the corners
- Tight or pointed shoes
- Naturally curved nails
- Stubbing or injuring the toe
- Sweaty feet, which soften the skin
What you can do at home
- Soak the foot in warm, salty water for 10 to 15 minutes, then dry it well
- Wear wide, comfortable shoes or sandals
- Keep the area clean and dry
- Let the nail grow out rather than cutting it shorter
What not to do
Don't dig into the corner or try to cut out the piece of nail yourself. It's easy to leave a sharp spike behind, which can make the problem worse and let infection in.
When to get help
Book an appointment if the toe is still sore after a few days, or if it keeps coming back. We can often gently free and trim the edge of the nail and give you advice to stop it happening again. Learn more on our ingrown toenail page.
See your GP or call NHS 111 if the toe is very red, hot or swollen, there's pus, the redness is spreading, or you feel unwell. You should also get it checked promptly if you have diabetes.
Quick answers
Can an ingrown toenail fix itself?
Mild ones sometimes settle as the nail grows out, but painful or recurring ones usually need help.
Do you do nail surgery?
We treat many ingrown toenails without surgery. If surgery is needed, we'll explain your options.
How can I stop it happening again?
Cut nails straight across, not too short, and wear shoes with enough room for your toes.
