Why The Edge Of Your Toenail May Become Painful, Red, And Swollen

It may begin as a little tenderness along the side of your big toe. Then your shoe starts pressing against it.

The skin becomes red and swollen, and suddenly even a bedsheet touching your toe feels uncomfortable.

One possible cause is an ingrown toenail.

An ingrown toenail develops when the edge or corner of a toenail grows into—or presses against—the surrounding skin. The big toe is affected most often, although other toenails can develop the problem too.

Some mild cases may improve with conservative care. Others become increasingly painful, repeatedly return, or develop signs of infection.

At Z-2-H Family Med & Urgent Care, our providers can evaluate appropriate toe and nail concerns and help determine whether an ingrown toenail or another condition may be responsible.

---

What Is An Ingrown Toenail?

An ingrown toenail occurs when part of the nail presses into the skin along the nail fold.

The surrounding tissue can become:

• Tender
• Red
• Swollen
• Irritated
• Painful

As the nail continues pressing into the area, inflammation may increase.

If bacteria enter damaged skin, an infection can also develop.

---

What Does An Ingrown Toenail Look Like?

Early signs may be subtle.

You might notice:

• Tenderness along one side of the nail
• Mild redness
• Slight swelling
• Pain when pressing the area

As the problem progresses, the skin may become more swollen and begin growing over the nail edge.

More advanced cases may develop:

• Significant tenderness
• Drainage
• Pus
• Bleeding
• Excess tissue around the nail

These symptoms deserve medical evaluation.

---

Where Do Ingrown Toenails Usually Develop?

They occur most commonly along one or both sides of the big toenail.

However, any toenail can potentially become ingrown.

The problem occurs where the nail edge and surrounding skin meet.

---

Why Does An Ingrown Toenail Hurt?

The nail repeatedly presses into sensitive skin.

Walking, running, or wearing shoes can add even more pressure.

This may cause:

• Inflammation
• Swelling
• Tenderness
• Throbbing
• Sharp pain when touched

Once the surrounding skin becomes swollen, the nail may press even more firmly against it.

---

What Causes Ingrown Toenails?

Several factors may contribute.

Common possibilities include:

• Cutting toenails too short
• Rounding the nail corners
• Tight shoes
• Narrow toe boxes
• Repeated pressure on the toes
• Toe injuries
• Naturally curved nails
• Nail shape
• Repetitive sports activity

Sometimes several factors occur together.

---

Can Cutting Your Toenails Wrong Cause Ingrown Nails?

Yes.

Cutting nails very short or deeply rounding the corners may encourage the surrounding skin to grow over the nail edge.

As the nail grows back, the edge may press into that skin.

For many people, trimming toenails relatively straight across rather than digging deeply into the corners may help reduce the risk.

---

Should You Cut A V Into The Toenail?

No.

You may have heard that cutting a V-shaped notch into the center of the nail will make the sides grow inward toward the notch.

That's a common home remedy, but it doesn't reliably change how the nail grows.

It may simply damage or unnecessarily shorten the nail.

---

Can Tight Shoes Cause Ingrown Toenails?

Tight footwear can contribute.

Shoes with narrow toe boxes may squeeze the toes together and place additional pressure along the nail folds.

This can be especially problematic when combined with:

• Curved nails
• Improper trimming
• Long periods of standing
• Running or sports

Your toes should have appropriate room inside your shoes.

---

Can Sports Cause Ingrown Toenails?

Certain activities can increase repeated pressure on the toes.

Examples may include:

• Running
• Soccer
• Football
• Hiking
• Dance
• Activities involving sudden stopping

Shoes that don't fit properly may make the problem worse.

Athletes who repeatedly develop painful toenails may benefit from reviewing both nail care and footwear.

---

Can A Toe Injury Cause An Ingrown Nail?

Yes.

Trauma can alter how the nail grows.

Examples include:

• Stubbing the toe
• Dropping something on the foot
• Repetitive pressure inside footwear
• Sports-related trauma

A damaged nail may also become:

• Discolored
• Loose
• Thickened
• Irregular

Not every painful nail after an injury is an ingrown toenail.

---

Can Ingrown Toenails Run In Families?

Nail shape can play a role.

Some people naturally have toenails that are more curved along the edges.

This may increase the likelihood of recurring ingrown toenails.

Family members can therefore experience similar problems even when their nail-care habits differ.

---

Can Children Get Ingrown Toenails?

Yes.

Children and teenagers can develop ingrown toenails.

Possible contributors include:

• Improper nail trimming
• Tight shoes
• Sports
• Rapid foot growth
• Naturally curved nails

Parents should pay attention when a child begins complaining that shoes hurt or avoids pressure on one toe.

---

Can An Ingrown Toenail Become Infected?

Yes.

When the nail damages the surrounding skin, bacteria can enter the area.

Possible signs of infection include:

• Increasing redness
• Increasing swelling
• Warmth
• Worsening pain
• Pus
• Drainage

If these symptoms develop, medical evaluation is appropriate.

---

Ingrown Toenail Vs. Paronychia

These conditions can overlap.

Ingrown Toenail

The nail edge presses into the surrounding skin.

Paronychia

This is an infection or inflammation involving the tissue around the nail.

An ingrown toenail can sometimes contribute to paronychia by damaging the skin and creating an entry point for bacteria.

---

Ingrown Toenail Vs. Toenail Fungus

Toenail fungus commonly causes changes such as:

• Thickened nails
• Discoloration
• Brittle nails
• Crumbling
• Distorted nail shape

An ingrown toenail more commonly causes localized pain and swelling along the nail edge.

A thickened fungal nail can sometimes contribute to nail-shape problems, so the two conditions may occasionally occur together.

---

Ingrown Toenail Vs. Gout

Both can cause significant big-toe pain, but they are very different conditions.

Ingrown Toenail

Pain is usually concentrated around the nail edge.

Gout

Often causes sudden, intense inflammation around a joint—commonly the joint at the base of the big toe.

Gout may cause:

• Severe joint pain
• Redness
• Swelling
• Warmth

A painful red toe shouldn't automatically be assumed to be an ingrown nail.

---

Ingrown Toenail Vs. Cellulitis

An uncomplicated ingrown toenail causes localized irritation near the nail.

Cellulitis is a bacterial infection involving deeper layers of the skin.

Warning signs can include:

• Expanding redness
• Increasing warmth
• Significant swelling
• Increasing pain
• Fever

Spreading redness beyond the immediate nail area deserves prompt evaluation.

---

Can An Ingrown Toenail Heal On Its Own?

Some mild cases may improve with conservative measures, particularly when addressed early.

However, an ingrown toenail may continue worsening if:

• The nail remains embedded
• Footwear continues applying pressure
• The nail is repeatedly cut incorrectly
• Infection develops

Recurring or significantly painful cases should be evaluated.

---

What Can You Do For A Mild Ingrown Toenail?

For an otherwise healthy person with a mild case and no signs of infection, conservative care may include:

• Keeping the foot clean
• Wearing roomy footwear
• Avoiding repeated pressure on the toe
• Allowing the nail to grow appropriately
• Avoiding aggressive cutting or digging

Home care is not appropriate for every patient, particularly people with diabetes, poor circulation, neuropathy, or signs of infection.

---

Can You Soak An Ingrown Toenail?

Warm-water soaks may help temporarily soothe a mildly irritated toe.

Afterward:

• Dry the foot carefully
• Keep the area clean
• Avoid prolonged moisture
• Wear comfortable footwear

A soak does not remove an embedded nail edge or treat a significant infection.

If symptoms worsen, seek medical care.

---

Should You Dig Out An Ingrown Toenail?

No.

Avoid using:

• Scissors
• Tweezers
• Needles
• Nail tools
• Other sharp objects

to dig deeply beneath the nail.

Doing so can:

• Damage the skin
• Cause bleeding
• Introduce bacteria
• Worsen inflammation
• Increase infection risk

Aggressive DIY "nail surgery" can turn a relatively minor problem into a more complicated one.

---

Should You Cut The Painful Corner Out?

Avoid repeatedly cutting deeply into the painful corner yourself.

It may provide temporary relief, but the nail can grow back and become ingrown again.

Deep cutting may also create:

• Sharp nail fragments
• Skin injuries
• Bleeding
• Infection

Recurring ingrown nails deserve proper evaluation.

---

Should You Pop Pus Around An Ingrown Toenail?

No.

Pus or significant drainage suggests possible infection.

Do not squeeze, puncture, or attempt to drain the area yourself.

Medical evaluation can determine whether:

• Infection is present
• Drainage is necessary
• Antibiotics are appropriate
• The ingrown portion of the nail needs treatment

---

Do Antibiotics Fix An Ingrown Toenail?

Not necessarily.

Antibiotics treat certain bacterial infections.

They do not automatically correct the underlying mechanical problem of a nail growing into the skin.

If infection is present, a healthcare provider will determine whether antibiotics are appropriate and whether the nail itself also requires treatment.

---

How Is An Ingrown Toenail Diagnosed?

Diagnosis usually begins with an examination.

A healthcare provider may evaluate:

• Nail shape
• Nail edge
• Redness
• Swelling
• Tenderness
• Drainage
• Surrounding skin
• Signs of infection

They may also ask about:

• Previous episodes
• Nail-trimming habits
• Footwear
• Injury
• Diabetes
• Circulation problems
• Numbness or neuropathy

Imaging is generally not necessary for a straightforward ingrown toenail.

---

How Are Ingrown Toenails Treated?

Treatment depends on severity.

Possible approaches may include:

• Conservative nail care
• Footwear modification
• Appropriate wound care
• Treatment of infection when present
• Partial nail removal in selected cases
• Procedures intended to reduce recurrence in selected patients
• Referral when appropriate

Not every patient needs a procedure.

---

What Is Partial Nail Removal?

For some painful or recurring ingrown toenails, a healthcare professional may remove the portion of the nail that is growing into the skin.

This is different from removing the entire toenail.

The exact procedure depends on:

• Severity
• Recurrence
• Infection
• Nail anatomy
• Patient health

A healthcare professional can explain what is appropriate for an individual case.

---

Does The Whole Toenail Have To Come Off?

Usually not.

Many procedures involve only the problematic portion of the nail.

Complete nail removal may be considered in certain circumstances, but it isn't automatically necessary for every ingrown toenail.

---

Will The Toenail Grow Back?

If only part of the nail is temporarily removed, that portion may grow back.

For recurrent cases, certain procedures may be used to reduce regrowth along the problematic edge.

The appropriate approach depends on the individual patient.

---

Why Does My Ingrown Toenail Keep Coming Back?

Recurrence may be related to:

• Nail shape
• Cutting nails too short
• Rounding the corners
• Tight footwear
• Repetitive toe pressure
• Sports
• Previous nail injury

Some people are simply more prone to recurring ingrown toenails.

Repeatedly performing aggressive home treatment usually doesn't address the underlying reason.

---

Why Are Ingrown Toenails More Concerning With Diabetes?

Diabetes can sometimes affect:

• Sensation
• Circulation
• Wound healing
• Infection risk

A person with reduced sensation may not recognize an injury early.

A small toe wound can therefore become more serious before it is noticed.

People with diabetes should be particularly cautious about cutting, digging into, or treating foot wounds themselves.

---

What If You Have Neuropathy?

Neuropathy can reduce the ability to feel:

• Pain
• Pressure
• Temperature
• Injury

That means an ingrown toenail or skin wound may be worse than it feels.

People with reduced sensation should inspect their feet regularly and seek appropriate care for new wounds, drainage, redness, or nail problems.

---

What If You Have Poor Circulation?

Reduced blood flow can interfere with healing.

If you have known circulation problems, avoid aggressive home procedures involving your feet.

Seek medical guidance for:

• Ingrown nails
• Cuts
• Wounds
• Blisters
• Skin-color changes
• New swelling

Foot problems may require additional caution in these circumstances.

---

Can Pedicures Cause Ingrown Toenails?

Improper nail trimming during a pedicure may contribute.

Cutting too deeply into the corners can leave sharp edges that later press into the skin.

Nail tools should also be appropriately cleaned to reduce infection risk.

Tell your nail technician if you are prone to ingrown toenails.

People with diabetes, neuropathy, circulation problems, or other high-risk foot conditions should ask their healthcare professional about safe foot and nail care.

---

How Should You Trim Toenails?

General nail-care tips may include:

• Trim nails relatively straight across
• Avoid cutting them excessively short
• Avoid digging deeply into the corners
• Use clean nail tools
• File sharp edges gently when appropriate

Toenails do not need to be perfectly square, but aggressively rounding the corners can increase the risk of the skin growing over the nail edge.

---

What Shoes Help Prevent Ingrown Toenails?

Choose shoes that fit appropriately.

The toe box should provide enough room so your toes aren't constantly compressed.

Avoid shoes that repeatedly:

• Squeeze the big toe
• Push the toes together
• Cause toenail pressure
• Make the painful area worse

Proper fit is particularly important for running, work, and sports footwear.

---

When Should You Schedule An Evaluation?

Consider having your toe evaluated if:

• Pain persists
• Redness or swelling is increasing
• The nail repeatedly becomes ingrown
• Walking becomes uncomfortable
• Shoes become difficult to wear
• Drainage develops
• You aren't sure what is causing the pain
• Home measures aren't helping

Earlier evaluation may prevent a worsening problem.

---

When Does An Ingrown Toenail Need Prompt Medical Care?

Seek prompt medical evaluation for:

• Pus
• Significant drainage
• Rapidly increasing swelling
• Spreading redness
• Increasing warmth
• Severe pain
• Fever
• Red streaking
• Significant skin breakdown

These findings may indicate infection or another complication.

---

When Should Someone With Diabetes Seek Care?

If you have diabetes, especially with neuropathy or circulation problems, seek medical guidance for a new:

• Foot wound
• Ingrown toenail
• Blister
• Drainage
• Significant redness
• Swelling
• Skin-color change

Avoid attempting to cut deeply into or drain the area yourself.

---

What To Expect During Your Visit

During an evaluation, your provider may:

• Ask when symptoms began
• Review previous ingrown toenails
• Examine the nail
• Assess redness and swelling
• Check for drainage
• Look for signs of infection
• Review nail-trimming habits
• Ask about footwear
• Review diabetes or circulation concerns
• Determine whether conservative treatment is appropriate
• Discuss a procedure or referral when necessary

The goal is to treat the current problem while reducing the chance that it keeps returning.

---

How Can You Help Prevent Ingrown Toenails?

Helpful habits may include:

• Don't cut nails extremely short
• Avoid aggressively rounding the corners
• Wear properly fitting shoes
• Keep feet clean and dry
• Use clean nail tools
• Address repetitive toe pressure
• Protect toes from injury
• Avoid digging into nail edges
• Monitor recurring problems

People at higher risk for foot complications may need individualized nail-care guidance.

Frequently Asked Questions

What Is An Ingrown Toenail?

An ingrown toenail occurs when the edge or corner of the nail presses into the surrounding skin, causing pain, redness, and swelling.

What Causes Ingrown Toenails?

Common contributors include cutting nails too short, rounding the corners, tight footwear, repetitive toe pressure, injury, and naturally curved nails.

Can An Ingrown Toenail Become Infected?

Yes. Damaged skin around the nail can allow bacteria to enter and cause infection.

Should I Dig Out An Ingrown Toenail?

No. Digging into the nail with scissors, tweezers, needles, or other sharp objects can cause injury and infection.

Should I Cut A V Into My Toenail?

No. Cutting a V into the center of the toenail does not reliably correct how the nail grows.

Do Antibiotics Cure An Ingrown Toenail?

Antibiotics may be used when a bacterial infection is present, but they do not necessarily correct the underlying nail edge pressing into the skin.

Does The Whole Toenail Need To Be Removed?

Not usually. When a procedure is necessary, only the problematic portion may need treatment in many cases.

Why Does My Ingrown Toenail Keep Coming Back?

Recurring ingrown nails may be related to nail shape, trimming technique, footwear, repeated pressure, sports, or previous injury.

Are Ingrown Toenails Dangerous For People With Diabetes?

They can be more concerning because diabetes may affect sensation, circulation, wound healing, and infection risk. People with diabetes should avoid aggressive home treatment and seek appropriate medical guidance for foot problems.

When Should I See A Doctor?

Consider evaluation for persistent pain, increasing redness or swelling, drainage, recurrent ingrown nails, difficulty walking, or symptoms that aren't improving.
