Why Does My Ingrown Toenail Keep Coming Back?

You trim the corner. It feels better.

A few weeks later, it hurts again.

You soak it, change your shoes, trim it one more time—and before long, you're dealing with the exact same painful corner of the exact same toe.

If you've had an ingrown toenail that keeps returning, there's usually a reason.

An ingrown toenail, medically known as onychocryptosis, occurs when the edge or corner of the nail grows into or presses against the surrounding skin. While some cases are relatively minor, others can become extremely painful, inflamed, or infected.

According to podiatric surgeon Dr. Krista Archer, recurring ingrown toenails often require looking beyond the painful corner to understand why the nail keeps growing that way in the first place.

What Does an Ingrown Toenail Feel Like?

Ingrown toenails most commonly affect the big toe, although they can occur on other toes.

Early symptoms may include tenderness along one side of the nail. As irritation progresses, you may notice:

• Redness
• Swelling
• Increasing sensitivity
• Pain when wearing shoes
• Pain when pressure is applied to the toe
• Overgrowth of tissue around the nail
• Drainage or signs of infection

Sometimes patients don't notice the problem until putting on a particular pair of shoes suddenly becomes uncomfortable.

Other times, even the pressure of a bedsheet against the toe can hurt.

Why Do Ingrown Toenails Happen?

There isn't one universal cause.

For many people, several factors work together.

The Natural Shape of Your Nail

Some nails naturally curve more than others.

If the nail plate is particularly curved or the sides of the nail sit deeply within the surrounding skin, the nail may be more likely to become ingrown.

This is one reason ingrown toenails can run in families.

You may simply have inherited a nail shape that makes them more likely.

How You Cut Your Toenails

Cutting deeply into the corners of a toenail can contribute to the problem.

When the remaining nail grows forward, the edge may begin pressing into the surrounding skin.

This creates a frustrating cycle: the corner hurts, so you cut it even shorter. It feels better temporarily, but as the nail grows back, the problem returns.

Shoes That Compress the Toes

Shoes with a narrow toe box can place pressure against the nail and surrounding skin.

This doesn't mean your shoes are always the underlying cause, but repeated compression can aggravate an already susceptible nail.

Nail Trauma

Dropping something on your toe, stubbing it, repetitive pressure from running, or other injuries can alter the way a nail grows.

If the nail becomes damaged or changes shape, it may become more likely to irritate the surrounding skin.

Why Does Cutting the Corner Make It Feel Better?

Because you're removing the part that's currently causing pressure.

The problem is that you may not be changing the way the nail grows.

Imagine cutting the sharp corner off something that continues moving in the same direction. You've temporarily removed the painful point—but as it grows forward again, you're back where you started.

That's why repeatedly performing what patients sometimes jokingly call "bathroom surgery" can become a never-ending cycle.

It can also make the problem more difficult to manage if the nail is cut so short that it's hard to access properly.

Should You Dig Out an Ingrown Toenail Yourself?

It's tempting.

You can see the corner. You know exactly where it hurts. And a pair of nail clippers or tweezers is sitting right there.

But repeatedly digging underneath the nail can injure the surrounding skin and create an opportunity for bacteria to enter.

This is particularly concerning if the toe is already inflamed.

People with diabetes, poor circulation, neuropathy, or other conditions that affect healing should be especially cautious about attempting to treat foot wounds or infected nails themselves.

If you're repeatedly cutting into the skin to get relief, it's probably time to stop chasing the corner and address the underlying problem.

Can an Ingrown Toenail Become Infected?

Yes.

When the nail penetrates or irritates the surrounding skin, bacteria can enter the area.

Signs that may indicate infection include increasing redness, warmth, swelling, drainage, worsening pain, or redness spreading beyond the immediate nail fold.

An infected ingrown toenail should be evaluated rather than simply covered with polish or ignored.

And while antibiotics may sometimes be appropriate when infection is present, medication alone doesn't necessarily solve the mechanical problem of a nail edge continuing to grow into the skin.

How Does a Podiatrist Treat an Ingrown Toenail?

Treatment depends on how severe the problem is.

A mild case may be managed conservatively, particularly when the nail hasn't significantly penetrated the skin and there are no signs of infection.

More painful or advanced ingrown nails may require removing the portion of nail that's causing the problem.

This is generally performed after numbing the toe with local anesthetic.

Rather than removing the entire toenail, a podiatrist can often remove only the narrow section along the affected side.

That distinction is important.

Patients sometimes imagine an ingrown toenail procedure means losing the whole nail. In many cases, it doesn't.

What If It Keeps Coming Back?

If the same border of the same toenail repeatedly becomes ingrown, simply removing that portion of nail may provide relief—but the nail can grow back and potentially become ingrown again.

For recurrent cases, a procedure may be considered to prevent that problematic section of nail from regrowing.

After the affected nail border is removed, the corresponding portion of the nail matrix—the tissue responsible for producing the nail—can be treated.

This is known as a matrixectomy.

The goal is to stop that narrow section of nail from growing back while leaving the majority of the toenail intact.

For the right patient, it can turn a recurring problem into a much more permanent solution.

Will My Toenail Look Strange After a Permanent Procedure?

This is one of the first questions many patients ask.

When only a small border of the nail is permanently removed, the remaining nail is simply somewhat narrower.

How noticeable that is depends on how much nail needs to be removed and the original shape of the toenail.

The objective is to remove enough of the problematic nail border to prevent recurrence while preserving as much normal nail as appropriate.

What About Pedicures?

Pedicures aren't inherently responsible for every ingrown toenail, but nail trimming technique matters.

Aggressively cutting down the sides of the nail or attempting to create a deeply rounded shape can contribute to problems in susceptible toes.

Toenails are generally better maintained without excavating deeply into the corners.

If you're prone to ingrown nails, tell your nail technician.

And if the toe is actively inflamed, draining, infected, or significantly painful, it should be medically evaluated rather than treated as a routine cosmetic nail concern.

Can You Prevent Ingrown Toenails?

Not every ingrown toenail is preventable, particularly when nail shape is a major factor.

But there are ways to reduce unnecessary irritation.

Avoid repeatedly cutting deeply into the corners of your toenails. Wear shoes that provide enough room for the toes. Pay attention to recurring pressure during running or exercise. And don't ignore a nail that repeatedly becomes painful in exactly the same location.

Most importantly, avoid creating a cycle where the nail has to become extremely painful before you do something about it.

When Should You See a Podiatrist?

An occasional mildly tender nail corner may settle with conservative care.

But you should consider evaluation when:

• The same ingrown toenail repeatedly returns
• Pain is becoming more severe
• There is significant redness or swelling
• The toe begins draining
• The nail is difficult to trim safely
• You can't comfortably wear shoes
• You suspect infection
• You have diabetes, poor circulation, neuropathy, or another condition that increases the risk of foot complications

Recurring problems are particularly important.

If you're cutting out the same corner every month or two, you're not really solving the problem.

You're maintaining it.

Stop Fighting the Same Toenail

Ingrown toenails can seem like a small problem—until every step reminds you that they're there.

And because trimming the painful corner can provide immediate relief, it's easy to get trapped in a cycle of repeatedly treating the symptom yourself.

Dr. Krista Archer evaluates not only the painful nail edge but also the nail's shape, surrounding skin, footwear, history of recurrence, and any signs of infection.

Sometimes conservative treatment is enough.

Sometimes removing the offending nail border provides the relief you need.

And when the same ingrown toenail keeps returning, a more permanent procedure may finally put an end to the cycle.

Because you shouldn't have to perform surgery on your own toe every time your nail grows back.
