How to Get Rid of an Infected Ingrown Toenail

An infected ingrown toenail usually starts as a minor nuisance and escalates into a throbbing, red, swollen mess at the side of your toe. Getting rid of it depends on how far along the infection has progressed: mild cases often respond to consistent home care over one to two weeks, while moderate or severe infections typically need a minor in-office procedure performed under local anesthesia. The good news is that even stubborn, recurring infections have effective surgical solutions with low recurrence rates, and most people are back on their feet quickly.

Recognizing the Stages of an Infected Ingrown Toenail

An ingrown toenail develops when the edge of the nail plate digs into the soft skin fold beside it, triggering pain, inflammation, and eventually infection. The clinical picture exists on a spectrum: early on you get tenderness and mild swelling along the nail border, then the skin may become red, warm, and increasingly painful as bacteria take hold. If left alone, the body’s response to chronic irritation can produce a mound of raw, puffy tissue called hypergranulation tissue that bleeds easily. At the far end of the spectrum, you have chronic infection with persistent drainage.

A few signs that your ingrown toenail has crossed into infected territory:

  • Spreading redness: The red area extends beyond the immediate nail fold and is warm to the touch.
  • Pus or drainage: You see yellowish or greenish fluid around the nail edge, sometimes with a foul smell.
  • Worsening pain: The pain intensifies when wearing shoes or even touching the toe, rather than staying mild and intermittent.
  • Granulation tissue: A small, raw-looking bump of tissue grows over the nail edge and bleeds with minimal contact.

If you notice red streaks traveling up from the toe, fever, or swelling in the entire foot, those are signs that infection is spreading beyond the local area, and you should see a healthcare provider the same day.

What Makes Ingrown Toenails Happen and Get Infected

The single biggest risk factor is how you cut your nails. A case-control study looking at predisposing factors found that improper nail trimming carried roughly seven times the odds of developing an ingrown toenail compared to people who trimmed correctly. Cutting the nail too short or rounding the corners encourages the edge to grow into the skin as it regrows. Other factors that significantly raised the risk included poor foot hygiene, excessive foot sweating, fungal nail infections, increased nail curvature, and higher body weight.

Tight or ill-fitting shoes also play a role, especially shoes that squeeze the toes together and press the nail into the skin fold. In a study of patients with severely curved “pincer” nails, about a quarter had a history of poorly fitting footwear, and many also had fungal nail infections complicating the picture.

3PubMed Central. A Clinical Study of 35 Cases of Pincer Nails

Understanding what drives the problem matters because the infection itself is almost always secondary. The nail creates a tiny wound in the skin fold, and bacteria from the environment colonize it. The fix, then, is twofold: address the infection and address the nail that caused it. Treating only one side of that equation is why so many people end up with recurrences.

Home Care for Mild Infections

If you catch the problem early, before pus is draining or granulation tissue has appeared, you can often manage it at home. The strategy is to reduce swelling, keep the area clean, and coax the nail edge away from the skin.

Soak the affected foot in warm water for 15 to 20 minutes, two to three times a day. Plain warm water works. Some people add Epsom salt, but the soaking itself is the active ingredient: it softens the skin and the nail, eases pain, and helps drain any early buildup. After soaking, gently dry the toe and try to lift the embedded nail edge slightly away from the skin. A small piece of clean cotton or dental floss tucked under the corner of the nail can keep it from digging back in. Replace the cotton daily to keep the area clean.

Apply an over-the-counter antibiotic ointment to the red area and cover the toe with a clean bandage. Wear open-toed shoes or shoes with a roomy toe box to minimize pressure. If the pain is manageable and you see improvement over three to five days, you are likely on the right track. If the redness is expanding, pain is getting worse, or pus appears, home care is not going to resolve the problem and it is time to see a provider.

Do You Actually Need Oral Antibiotics?

This is where many people’s assumptions are wrong. For a locally infected ingrown toenail, oral antibiotics by themselves are not very helpful. A study that compared different approaches found that people who had the offending nail edge removed along with a chemical treatment to the nail root healed in about two weeks, whether or not they also took a course of oral antibiotics. The group that took antibiotics alone before having the procedure done actually healed more slowly, not faster.

4PubMed. Are antibiotics necessary in the treatment of locally infected ingrown toenails?

The reason is straightforward: the nail edge is a foreign body jabbing into your skin. As long as it stays there, bacteria have a protected environment to thrive in, and antibiotics cannot fully clear an infection around a persistent foreign object. Removing the offending nail border treats the root cause and lets the body’s immune system finish cleaning up. Antibiotics become genuinely important when the infection has spread beyond the toe, such as into the surrounding foot tissue, or in people with compromised immune systems or diabetes. But for a typical locally infected ingrown toenail, the procedure is the treatment.

In-Office Procedures for Infected Ingrown Toenails

When home care fails or the infection is too advanced for conservative measures, the standard approach is a minor procedure done under local anesthesia in a doctor’s office. You do not need to go to an operating room. The toe is numbed with a local anesthetic injection, the offending strip of nail is removed, and in most cases the exposed nail root is treated with a chemical agent to prevent that strip from growing back.

The most common procedure is partial nail avulsion with chemical matricectomy. The doctor removes only the sliver of nail that is digging into the skin, then applies a chemical (usually phenol, sodium hydroxide, or trichloroacetic acid) to the nail matrix underneath. This kills the root cells in that small strip so the problematic edge does not regrow. Without the chemical step, recurrence rates are substantially higher. One study found a recurrence rate of about one in five when the nail strip was removed without chemical treatment, compared to zero recurrence when phenol matricectomy was added.

5Scientific Research Journal of Medical Sciences. A Comparative Study of Partial Nail Avulsion with Phenol Matricectomy 50% Versus Partial Nail Avulsion Alone Regarding Complications and Recurrence Rate

A systematic review and meta-analysis confirmed this pattern broadly: combining chemical and surgical matricectomy reduces recurrence risk compared to surgery alone.

6PubMed Central. Long-Term Outcomes of Surgical and Chemical Matricectomy for Ingrown Toenail Management: A Retrospective Study

Comparing Surgical and Chemical Approaches

Several chemical agents are used for matricectomy, and they each have slightly different recovery profiles. A study comparing trichloroacetic acid (TCA), sodium hydroxide, and phenol found that TCA produced less post-operative pain and drainage, and the wound healed faster, with no recurrences at one year across any group.

Sodium hydroxide also appears to outperform traditional wedge resection (where the doctor physically cuts out a wedge of nail and tissue). One comparison found that patients treated with sodium hydroxide had lower rates of both recurrence and post-operative infection than those who had a wedge resection.

For children, the Vandenbos procedure, which removes the skin fold rather than the nail, has shown a recurrence rate of only about 2% compared to roughly 11% for standard wedge resection.

One tradeoff worth knowing: chemical matricectomy tends to heal more slowly than purely surgical approaches. A network meta-analysis found that chemical matricectomy was associated with longer healing times than minor surgery or conventional wedge excision, even though recurrence rates and pain levels were similar.

An aesthetic reconstruction technique, where the doctor surgically reshapes the nail fold after nail removal, has shown particularly fast healing of about eight days versus roughly three weeks for phenol matricectomy, with comparable recurrence rates under 3% in both groups.

What Recovery Looks Like

After a partial nail avulsion with chemical matricectomy, expect a few days of mild to moderate discomfort that responds to basic painkillers. A systematic review of randomized trials found that shorter applications of phenol reduced healing time, and that overall patient satisfaction with these procedures was high.

12PubMed Central. A systematic review and meta-analysis of randomised controlled trials of surgical treatments for ingrown toenails part II: healing time, post-operative complications, pain, and participant satisfaction

Post-operative wound care is simpler than most people expect. A study that randomized patients into three groups, acidic soap baths, alkaline soap baths, or just keeping the bandage on, found that at two weeks all three groups had the same outcomes and none needed antibiotics. Interestingly, patients who simply kept the bandage on had lower signs of infection at one week than those using either type of soap bath.

Most people return to normal shoes within a week or two, though complete healing of the nail bed can take three to six weeks depending on the method used. Avoid strenuous exercise or prolonged standing for the first few days. Keep the toe clean and dry, change the bandage daily, and watch for signs that the infection is returning rather than resolving.

Nail Braces as a Non-Surgical Option

If you have a recurring ingrown toenail but want to avoid surgery, nail bracing is an option that has gained traction. A small metal or composite brace is bonded across the surface of the toenail, applying a gentle lifting force that gradually flattens the nail’s curve and pulls the edges away from the skin fold. The brace is painless to apply, requires no anesthesia, and allows you to keep wearing your normal shoes.

14PubMed Central. Ingrown toenails (unguis incarnatus): Nail braces/bracing treatment

A prospective study tracking outcomes at one, three, and six months found that essentially all treated nail sides achieved an excellent or fair result by six months, with a recurrence rate of about 7%.

15Dermatologic Surgery. Efficacy of Nail Braces for Acute and Chronic Ingrown Toenails: A Prospective Study

There is a catch: nail braces work best for ingrown toenails caused by excessive curvature of the nail, not for acutely infected toenails with significant pus and granulation tissue. If your toenail is actively infected, the infection needs to be addressed first, either through home care or a procedure. Once the acute infection clears, a brace can help reshape the nail to prevent the problem from coming back.

Who Needs to Be Especially Careful

People with diabetes deserve special attention. Even a small toe infection in a diabetic foot can escalate fast because of reduced blood flow and impaired sensation. If you have diabetes and notice an ingrown toenail starting to look red or swollen, do not try to manage it at home beyond the first day or two. See a podiatrist or your primary care provider early. The threshold for professional intervention is much lower in this group.

Age also matters in unexpected ways. A large population-based study found that ingrown toenail incidence peaks twice across a lifetime: once during the teenage years and again in the fifties.

16PubMed. Epidemiology and bone-related comorbidities of ingrown nail: A nationwide population-based study

The teenage peak makes sense: rapid foot growth, sports, sweaty shoes, and often poor nail-trimming habits converge. The second peak in middle age is less obvious but likely relates to thickening nails, changes in nail curvature, and higher rates of fungal nail infection that alter how the nail grows. Both groups are well served by the same preventive habits: straight-across trimming, well-fitting shoes, and prompt attention when a nail starts bothering them.

Preventing the Next One

Given that improper trimming is the top risk factor by a wide margin, the most impactful change is learning to cut your toenails correctly. Trim them straight across, not curved along the toe’s contour, and leave them long enough that the corners sit on top of the skin fold rather than being buried under it. A good rule of thumb is to keep nails even with the tip of the toe.

Shoes matter too. Avoid anything that squeezes your toes together. If your big toe nail is pressing against the inside of your shoe when you walk, the shoe is too narrow. Moisture control helps as well: excessive sweating was a significant independent risk factor for ingrown toenails, so breathable socks and rotating between pairs of shoes to let them dry out can make a real difference.

2PubMed. Evaluation of predisposing factors in patients with ingrown toenails: a prospective, case-control study

If you have a fungal nail infection that is making the nail thick, crumbly, or abnormally curved, treating the fungus can reduce your odds of recurring ingrown nails. Similarly, if your nail is naturally very curved, a podiatrist can monitor it and intervene with bracing before it reaches the point of infection. Prevention is never as dramatic as treatment, but given how miserable an infected ingrown toenail can be, a bit of attention to trimming and footwear goes a long way.

What to Do About Pain Before and During Treatment

Before you get to a provider, over-the-counter ibuprofen or acetaminophen can take the edge off the pain. Ibuprofen also reduces inflammation, which helps with the swelling around the nail fold. Soaking in warm water before bed can ease nighttime discomfort enough to let you sleep.

During an in-office procedure, the toe is numbed using a local anesthetic block. Two common techniques are the V-block and the H-block. A comparative study found that the V-block provides rapid onset and effective pain relief for straightforward procedures, while the H-block offers more thorough and longer-lasting numbness for more complex surgeries.

17Biological and Clinical Sciences Research Journal. A COMPARATIVE STUDY OF ANESTHETIC BLOCK TECHNIQUES (V-BLOCK VS. H-BLOCK) FOR REMOVAL OF INGROWN TOENAIL

Either way, the procedure itself should be painless once the block takes effect. The injection to numb the toe is the least pleasant part, and it lasts about ten seconds. Post-procedurally, discomfort typically lasts one to two days and responds well to simple painkillers. Most people describe the experience as far less painful than living with the infected nail was.
