An infected ingrown toenail needs a combination of reducing the infection and removing the piece of nail digging into your skin. Mild infections with slight redness and swelling can often be managed at home with soaks, proper drainage, and topical antiseptics. But if you see pus that keeps returning, swelling spreading beyond the toe, or red streaks moving up your foot, you need professional treatment.
How to Tell If It’s Infected
An ingrown toenail by itself causes pain and pressure where the nail edge presses into the skin fold. Infection adds a layer of symptoms on top of that. Yellow, white, or green discharge around the nail is the clearest sign. The skin will look red and feel noticeably warmer than the surrounding area, and the swelling may feel tight or throbbing rather than just tender.
Most infected ingrown toenails stay localized to the toe. The situation becomes more serious when swelling extends beyond the toe into the foot, or when you notice red streaks radiating outward from the toe. Those streaks indicate the infection is moving through your lymphatic system. A fever paired with increasing toe pain means your body is fighting a deeper infection. At that point, home treatment is no longer enough.
Home Treatment for Mild Infections
If the infection is early (some redness, mild swelling, tenderness but no significant pus), home care can resolve it. The goal is to soften the skin around the nail, gently free the embedded edge, and keep the area clean so the infection clears.
Soak your foot in warm water with Epsom salt for about 10 minutes. Do this two to three times a day. The warm soak softens both the nail and the inflamed skin fold, making it easier for the nail edge to release. After soaking, dry the toe thoroughly and apply a topical antibiotic ointment to the affected area. If you can see the nail edge that’s digging in, try gently lifting it and placing a tiny piece of clean cotton or dental floss underneath to keep it from pressing back into the skin. Replace this each time you soak.
Wear open-toed shoes or sandals while you’re treating it. Any pressure from tight or closed-toe footwear pushes the skin into the nail edge and makes everything worse. Between soaks, keep the toe clean and dry.
You should see noticeable improvement within three to five days. If the redness is spreading, the pain is getting worse, or pus keeps returning after you clean it, home treatment isn’t working and you need to see a podiatrist or your doctor.
Why Oral Antibiotics Alone Won’t Fix It
Many people assume antibiotics are the answer to an infected ingrown toenail. Research tells a different story. Oral antibiotics have not been shown to significantly improve healing times for ingrown toenails. A study comparing patients who received antibiotics alongside a nail procedure to those who had the procedure alone found no meaningful difference in how quickly they healed. Antibiotics can help control a spreading infection, but they don’t address the root cause: a piece of nail physically embedded in your skin. Until that nail edge is removed, the infection will keep coming back.
What Happens at the Doctor’s Office
Ingrown toenails are staged by severity. Mild and moderate cases (stages 1 and 2) are usually treated conservatively with trimming of the nail spicule and topical antibiotics. Stage 3, where there’s significant infection, overgrown tissue around the nail, or repeated episodes, requires a minor surgical procedure.
The most common procedure is a partial nail avulsion with chemical matrixectomy. Your doctor numbs the toe with a local anesthetic, removes the ingrown portion of the nail, and then applies a chemical (typically phenol) to the exposed nail matrix. This destroys the root cells along that strip so the problematic edge doesn’t grow back. The procedure takes about 20 minutes.
The success rates vary dramatically depending on the technique. Simple nail edge removal without treating the matrix has a recurrence rate of 39%, meaning roughly two out of five people will deal with the same problem again. Total nail removal (pulling the entire nail) is even worse, with an 83% recurrence rate. By contrast, partial removal with phenol treatment of the matrix has a success rate above 99% in clinical studies, with only rare recurrences over a two-year follow-up period.
Recovery After a Procedure
Most people return to work or school the next day. The toe will be bandaged, and you’ll need to redress it every other day until the wound fully heals. For a partial nail removal, healing typically takes six to eight weeks. If the entire nail was removed, expect eight to ten weeks.
During recovery, wear shoes with enough room that they don’t press on the toe. Avoid tight footwear entirely. Swimming is off limits until the wound has fully closed, and you should cut back on strenuous exercise and sports during the healing period. The toe may ooze a clear or slightly yellowish fluid for the first few weeks, which is normal drainage and not a sign of reinfection.
Diabetes and Other High-Risk Conditions
If you have diabetes, do not try to treat an infected ingrown toenail at home. Diabetes reduces blood flow to the feet and damages the nerves, which means you may not feel how severe the infection actually is. Symptoms like pain, swelling, and warmth that would normally alert you to a worsening problem can be muted or absent entirely. What looks like a minor ingrown nail can progress to a serious foot infection much faster in someone with diabetes. Podiatrists recommend that all people with diabetes seek professional care for any ingrown toenail, even one that doesn’t appear infected yet.
The same caution applies if you have peripheral vascular disease, are on immunosuppressive medications, or have any condition that impairs wound healing.
Preventing Recurrence
The way you cut your toenails is the single biggest factor you can control. Cut straight across rather than rounding the corners. When you curve the nail at the edges, the corners can grow downward into the skin fold as the nail lengthens. Keep the nail roughly even with the tip of the toe. Cutting too short encourages the surrounding skin to fold over the nail edge as it grows out.
Footwear matters too. Shoes that squeeze your toes together, especially in the toe box, push skin against nail edges repeatedly. This is why ingrown toenails are more common in people who wear narrow dress shoes, pointed heels, or athletic shoes that are a half size too small. If you’re prone to ingrown nails, prioritize shoes with a wide, roomy toe box. Socks that are too tight can have the same effect.
Some people are simply more prone to ingrown toenails because of their nail shape. Nails that are naturally curved or fan-shaped tend to dig into the surrounding skin more easily. If you’ve had multiple recurrences despite proper trimming and footwear, a permanent partial matrixectomy can eliminate the problem for good by preventing that strip of nail from ever regrowing.
