An ingrown nail happens when the edge of a toenail grows into the skin beside it. That skin reacts like an injury — it gets red, swollen, and sore. Most mild cases improve at home with warm soaks, careful trimming, and shoes that stop pressing on the toe. If the area is badly infected, keeps coming back, or you have diabetes or poor circulation, a doctor needs to treat it.
What Causes An Ingrown Nail?
The nail edge curls down and pierces the skin along the side of the toe. The body responds with inflammation — redness, swelling, warmth, and pain. If bacteria get into that break in the skin, it can turn into an infection with pus and more swelling.
Several things push a nail into the skin:
- Cutting nails too short or rounding the corners instead of cutting straight across
- Shoes that squeeze the toes together or press on the top of the toe
- Injury to the toe, like stubbing it or dropping something on it
- Naturally curved or unusually thick nails
- Repeated pressure from running, kicking, or standing for long periods
The big toe is the most common site. It takes the most pressure from shoes and from walking.
How To Get Rid Of Ingrown Nails At Home
Home care works for mild cases — tenderness and redness without pus or spreading swelling. The goal is to reduce pressure on the skin and let the inflammation settle.
Soak the foot in warm water for about 15 to 20 minutes, a few times a day. Warm water eases swelling and softens the nail. Keep the foot clean and dry between soaks. Some clinicians suggest adding Epsom salt to the soak, though the evidence that it does more than plain warm water is limited.
Take pressure off the toe. Wear open-toed shoes or sandals while it heals. If you must wear closed shoes, choose a wide toe box. Do not wear tight socks or pointed shoes.
You can gently lift the nail edge. After soaking, when the nail is soft, slide a small piece of clean cotton or dental floss under the edge of the nail. This lifts the nail away from the skin so it can grow out. Change the cotton daily. Do not force it — if it hurts, stop. This is a widely used technique, but not one with strong trial evidence behind it. It helps some people and not others.
An over-the-counter pain reliever can ease discomfort. If you take other medications or have health conditions, check with a pharmacist or doctor first.
Do not try to dig the nail out yourself with scissors, a knife, or any sharp tool. This is the most common way a mild problem becomes an infected one. Cutting a notch in the nail or trying to cut out the corner rarely helps and often makes it worse.
If the toe gets more swollen, develops pus, or the redness spreads up the foot, stop home care and see a doctor.
When Should You See A Doctor For An Ingrown Nail?
See a doctor if the toe is infected or if home care has not helped after a few days. Signs that it needs medical care include:
- Pus or drainage from the side of the nail
- Redness and swelling that spread beyond the toe
- Increasing pain or pain that keeps you from walking
- Fever or chills
- No improvement after several days of home care
- The nail is deeply curved or the problem keeps coming back
Some people should see a doctor right away rather than trying home care at all. This includes anyone with diabetes, poor circulation in the legs or feet, nerve damage in the feet, or a weakened immune system. In these groups, a minor toe problem can become a serious infection quickly, and the usual signs of infection may be muted or absent. If you have diabetes and any new foot problem, contact your care team rather than treating it yourself.
What Does A Doctor Do For An Ingrown Nail?
Treatment depends on how bad it is and how often it has happened.
For a mild infection, a doctor may simply lift the nail edge and place a small piece of material under it to separate the nail from the skin. They may prescribe an antibiotic if there is an infection. Antibiotics treat the infection but do not fix the nail itself, so the nail still needs to grow out past the skin edge.
For a more stubborn or recurring nail, part of the nail may need to be removed. The doctor numbs the toe first, then removes the piece of nail growing into the skin. This is called partial nail avulsion. It relieves the problem right away.
To keep the nail from growing back into the skin, the doctor may also destroy the nail-growing tissue along that edge. This is done with a chemical such as phenol, or with a small electrical current or laser. Destroying the growth tissue makes the nail narrower and much less likely to ingrow again. This is the standard approach for nails that keep causing trouble. Removing part of the nail without treating the growth tissue means the problem is more likely to return.
In severe or long-standing cases, the whole nail may be removed. This is less common and usually saved for nails that cannot be salvaged.
Recovery is usually quick. Most people can walk normally within a day or two, though the toe stays tender for a while. It can take several weeks for the nail area to fully heal. Your doctor will give you specific instructions for keeping it clean and changing dressings.
How Do You Prevent Ingrown Nails From Coming Back?
Most prevention comes down to how you cut your nails and what you put on your feet.
Cut toenails straight across. Do not round the corners or cut them shorter than the tip of the toe. The nail should be even with, or just slightly longer than, the end of the toe. Use clean, sharp nail clippers. Cut after a bath or shower, when the nail is soft.
Wear shoes that fit. There should be about a finger’s width of space between the end of your longest toe and the front of the shoe. The toe box should be wide enough that your toes are not squeezed together. Avoid pointed shoes and high heels for long periods.
Keep your feet clean and dry. If you sweat a lot or wear tight shoes for work, change socks and let your feet air out when you can.
If you have diabetes or circulation problems, do not cut your own toenails if you have any trouble seeing or reaching your feet. Have a podiatrist or trained foot care provider do it. This is one of the most reliable ways to avoid a serious foot problem.
Why Do Some Ingrown Nails Keep Coming Back?
Recurring ingrown nails usually come from one of two things: the shape of the nail or the way it is being cut and pressed.
Some people have nails that are naturally wide at the base and curve sharply at the edges. That shape makes the nail more likely to dig into the skin no matter how carefully it is cut. For these people, home care often fails over and over, and the lasting fix is a procedure that narrows the nail by removing the growth tissue along the edge.
The other common cause is a cycle. The nail ingrows, the person cuts the corner to relieve it, the nail grows back with a sharper edge, and it ingrows again. Breaking that cycle usually means letting the nail grow out past the skin edge without cutting the corners, even though it is tempting to trim them.
If a nail has been treated and keeps returning, ask about permanent removal of the edge growth tissue. It is a small procedure and it changes the shape of the nail for good.
Frequently Asked Questions
How do I get rid of an ingrown nail fast?
Soak the foot in warm water, keep pressure off the toe, and gently lift the nail edge with a bit of cotton after soaking. If there is pus, spreading redness, or no improvement in a few days, see a doctor.
Should I cut out my ingrown toenail myself?
No. Digging out the nail with a sharp tool is the most common way a mild problem turns into an infected one. Let a doctor remove the nail edge if it needs to come out.
When should I see a doctor instead of treating it at home?
See a doctor if there is pus, spreading redness, fever, or pain that keeps you from walking, or if home care has not helped after a few days. If you have diabetes or poor circulation, contact your care team right away.
Will an ingrown nail go away on its own?
A mild one can improve as the nail grows past the skin edge, especially with warm soaks and looser shoes. One that is infected or keeps returning usually needs medical treatment.
