If your ingrown toenail is showing signs of infection, the first step is to soak it in warm water, apply an over-the-counter antibiotic ointment, and monitor it closely over the next day or two. Mild infections caught early can resolve at home, but if you see pus, spreading redness, or increasing pain, you need professional treatment. Here’s how to tell what you’re dealing with and what to do at each stage.
Infected or Just Irritated?
A simple ingrown toenail hurts. The skin along one or both sides of the nail looks red, feels tender when you press on it, and may be slightly swollen. That’s irritation, not infection, and it usually responds well to home care.
Infection is a step beyond that. You’ll notice pus (white, yellow, or greenish fluid) seeping from the edge of the nail, warmth radiating from the toe, and redness that’s spreading beyond the immediate nail fold onto the surrounding skin. The pain typically shifts from pressure-related tenderness to a steady throbbing that can wake you up at night. Some people notice a foul smell. If you see red streaks moving away from the toe toward your foot, or you develop a fever, the infection is advancing and you need medical attention the same day.
Home Treatment for Mild Infections
Warm soaks are the foundation of home care. Fill a basin with a gallon of lukewarm water and dissolve about half a cup of Epsom salt in it, then soak your foot for 15 minutes. Do this two to three times a day. The warm water softens the skin around the nail, helps draw out minor drainage, and reduces swelling enough that the nail edge may free itself from the skin fold.
After each soak, dry your foot thoroughly and apply a thin layer of over-the-counter antibiotic ointment (the kind you’d use on a cut) along the edge where the nail is digging in. Cover it with a clean bandage. Between soaks, wear open-toed shoes or loose-fitting footwear so nothing presses on the inflamed area.
You can also try gently lifting the corner of the nail away from the skin and tucking a tiny piece of clean cotton or waxed dental floss underneath. This creates a small gap that helps the nail grow over the skin rather than into it. Replace the cotton after each soak to keep it clean.
Over-the-counter ingrown toenail kits typically contain a sodium sulfide gel that softens the nail over several days, making it easier to trim the embedded edge. You apply the gel daily for up to seven days or until the nail is soft enough to cut. These products work best for mild cases where the nail just needs to be freed from the skin.
For pain, a standard anti-inflammatory like ibuprofen helps with both discomfort and swelling. If you’ve been doing soaks and applying ointment for two to three days and the redness, pus, or pain is getting worse instead of better, home treatment has run its course.
When Home Care Isn’t Enough
A doctor or podiatrist can address an infected ingrown toenail much more effectively than you can at home, and the procedure is simpler than most people expect. The most common approach is a partial nail avulsion: after numbing the toe with a local anesthetic, the provider removes the strip of nail that’s pressing into the skin. The whole thing takes minutes.
Research published in the Journal of the American Podiatric Medical Association shows that once the offending nail edge is removed, localized infection typically clears on its own without antibiotics. This is actually a well-studied finding: oral antibiotics before or after the procedure don’t improve outcomes for most patients. Your doctor may still prescribe them if the infection is severe or spreading, but for a standard infected ingrown nail, removing the embedded nail edge is the treatment.
After the procedure, the wound generally heals within a few weeks. You’ll keep the toe bandaged, soak it as directed, and avoid tight shoes during recovery. The nail grows back over the following 12 to 18 months.
Preventing It From Coming Back
Ingrown toenails have a frustrating tendency to recur, especially on the big toe. If yours keeps coming back, your provider may recommend a chemical matrixectomy. During this procedure, after removing the problematic nail border, a chemical is applied to the nail root to permanently prevent that strip of nail from regrowing. Recurrence rates after this procedure are low. In one comparative study, only four to five patients out of roughly 30 in each group experienced regrowth.
For everyday prevention, how you trim your nails matters more than almost anything else. The American Academy of Dermatology recommends cutting toenails straight across rather than rounding the corners. Use a toenail clipper (not fingernail scissors, which encourage curved cuts) and don’t trim them too short. The nail should be roughly even with the tip of your toe.
Footwear plays a surprisingly large role. Shoes with a narrow or pointed toe box compress your toes together and push the nail folds against the nail edge, essentially recreating the conditions for an ingrown nail with every step. Look for shoes with a wide toe box where your toes can spread naturally. If you can’t wiggle your toes inside the shoe, it’s too tight. This is especially important for people who spend long hours on their feet or who exercise in snug athletic shoes.
Special Risks for People With Diabetes
If you have diabetes, even a minor ingrown toenail infection warrants professional care rather than home treatment. Diabetes narrows and hardens blood vessels over time, reducing circulation to the feet. With less blood flow, your immune system can’t fight infection as effectively, and wounds heal slowly. What starts as a small cut or ingrown nail can progress to a serious infection. The American Diabetes Association notes that even small foot ulcers can escalate to infections that risk limb loss. If you have diabetes or any condition that affects circulation or sensation in your feet, and you notice numbness, a sore, or a cut that isn’t healing, contact your provider right away rather than managing it on your own.
