An infected ingrown toenail can usually be healed at home if caught early, using a combination of warm soaks, proper bandaging, and careful nail management. Most mild infections improve within a few days of consistent home care. But if you see pus, spreading redness, or increasing pain, the infection may need professional treatment, including antibiotics or a minor procedure to remove part of the nail.
How to Tell If Your Ingrown Toenail Is Infected
An ingrown toenail starts with pain and tenderness along the edge of the nail where it digs into the skin. That alone doesn’t mean infection. Infection sets in when bacteria enter the broken skin, and the signs are distinct: the skin around the nail becomes red, swollen, and warm to the touch. You may notice pus (white, yellow, or greenish discharge) oozing from the area.
A mild infection stays localized to the skin right next to the nail. A more serious infection spreads outward. If the redness extends beyond the toe, you develop a fever or chills, or you see red streaks moving up from the toe, the infection may have reached deeper tissue. This is cellulitis, a bacterial skin infection that can lead to dangerous complications if left untreated. That situation needs medical attention the same day.
Home Treatment for a Mild Infection
If the infection is limited to some redness, swelling, and tenderness around the nail edge, home care is a reasonable first step. The goal is to reduce swelling, draw out infection, and gently free the nail from the skin.
Start with warm salt water soaks. Add two tablespoons of Epsom salt (or regular table salt) per gallon of warm water and soak your foot for 20 minutes. Do this two to three times a day. The warm water softens the skin and nail, eases pain, and helps flush bacteria from the area. After each soak, dry the toe thoroughly.
Once the skin is soft from soaking, you can try to gently lift the edge of the ingrown nail away from the skin. Place a small piece of clean cotton or dental floss under the nail edge to encourage it to grow above the skin rather than into it. Replace this material after each soak so bacteria don’t accumulate.
After repositioning the nail, apply petroleum jelly to the tender area and cover it with a bandage. Petroleum jelly keeps the wound moist and protected, which promotes healing and reduces friction from socks and shoes. If the pain is significant, an over-the-counter pain reliever like ibuprofen or acetaminophen can help. Ibuprofen also reduces inflammation, which makes it a good choice when the area is swollen.
Wear open-toed shoes or roomy footwear during this time. Tight shoes press the nail further into the skin and make everything worse.
When Home Care Isn’t Enough
Give home treatment three to five days. If the redness is spreading, the pain is worsening, or pus is increasing rather than clearing up, the infection has likely progressed beyond what soaks and bandaging can resolve. At that point, you need professional care.
Your doctor may prescribe oral antibiotics to fight the infection. In some cases, a corticosteroid cream is prescribed to apply after soaking to bring down inflammation. But medications alone won’t fix the underlying problem if the nail is deeply embedded in the skin. That’s where minor procedures come in.
What Happens During a Nail Procedure
The most common procedure is a partial nail avulsion, where a doctor numbs the toe with a local anesthetic and removes the strip of nail that’s digging into the skin. It sounds worse than it feels. With the numbing, the procedure itself is painless, and it typically takes about 10 minutes.
For ingrown toenails that keep coming back, the doctor often adds a chemical treatment (usually phenol) to the exposed nail root after removing the nail strip. This destroys the cells that produce that section of nail, so it doesn’t grow back. Adding this step is more effective at preventing recurrence than removing the nail strip alone.
Recovery is straightforward. The site gets redressed after about three days. From there, you clean the toe daily after showering with salt water, apply an antiseptic ointment, and keep it covered with a simple dressing. Full healing takes two to three weeks. Most people return to normal activities within a day or two, though you’ll want to avoid running or tight shoes until the site has closed up.
People at Higher Risk for Complications
For most people, an infected ingrown toenail is painful but manageable. For some, it’s genuinely dangerous. If you have diabetes, peripheral artery disease, or any condition that reduces blood flow to your feet or weakens your immune system, even a mild-looking infection can escalate quickly. Poor circulation means your body can’t deliver immune cells to the area efficiently, and reduced sensation means you might not feel how bad the infection has become. If you fall into this category, skip the home treatment phase and go straight to a healthcare provider at the first sign of infection.
Preventing Recurrence
Ingrown toenails often come back, especially if the habits that caused them don’t change. The single most important prevention step is cutting your toenails straight across rather than rounding the corners. When you curve the edges, the nail is more likely to grow into the skin as it lengthens. Use a proper toenail clipper (not fingernail scissors) and don’t cut them too short. The nail edge should be roughly even with the tip of the toe.
Footwear matters just as much as trimming technique. Shoes that squeeze the toes push the nail into the surrounding skin with every step. This is especially common with narrow dress shoes, pointed-toe styles, and athletic shoes that are a half-size too small. Your toes should be able to wiggle freely. If you’re prone to ingrown toenails and you spend long hours on your feet, this one change can make a significant difference.
Keeping your feet clean and dry also reduces the chance of infection if an ingrown nail does start to develop. Bacteria thrive in the warm, moist environment inside shoes, so moisture-wicking socks and rotating between pairs of shoes can help lower your baseline risk.
