Why My Nail Grows Into the Skin: Causes, Treatment, and Prevention Guide (Ingrown Nail)

When your nail grows bigger and starts going inside the skin, it can be very painful and uncomfortable. This condition is commonly known as an ingrown nail. It usually affects the toenails, especially the big toe, but it can also happen to fingernails.

In this complete guide, you will learn:

What an ingrown nail is
Why it happens
Symptoms and warning signs
Home remedies
Medical treatments
Prevention tips

Let’s understand everything in detail.

What Is an Ingrown Nail?

An ingrown nail happens when the edge or corner of the nail grows into the surrounding skin instead of growing straight out. The medical term for this condition is onychocryptosis.

When the nail digs into the skin, it can cause:

Pain
Redness
Swelling
Infection
Pus formation (in severe cases)

If not treated early, it can become very painful and infected.

Why Does My Nail Go Under the Skin When It Grows?

There are several reasons why your nail grows into the skin when it becomes long.

1. Improper Nail Cutting

This is the most common cause.

If you:

Cut nails too short
Cut them in a curved shape
Cut the corners deeply

The nail may grow sideways into the skin.

Tip: Always cut nails straight across, not round.

2. Tight Shoes

Wearing tight shoes puts pressure on your toes. This pressure pushes the nail into the skin.

People who wear:

Narrow shoes
Tight socks
High heels
Sports shoes for long hours

Are at higher risk.

3. Injury to the Nail

If you:

Hit your toe
Drop something heavy on it
Injure the nail during sports

The nail may grow abnormally and go under the skin.

4. Naturally Curved Nails

Some people naturally have nails that curve downward. When they grow longer, they press into the skin easily.

This is a genetic condition in many cases.

5. Poor Foot Hygiene

Sweaty or dirty feet increase the risk of infection and swelling, which can worsen the condition.

Symptoms of an Ingrown Nail

At the beginning, symptoms may be mild. But if ignored, they can become serious.

Early Symptoms:

Mild pain on one side of the nail
Tenderness when touching
Slight redness

Moderate Symptoms:

Swelling
Increased pain
Skin growing over the nail edge

Severe Symptoms (Infection):

Pus
Bad smell
Bleeding
Severe pain
Fever (in rare cases)

If you notice pus or severe pain, you should see a doctor immediately.

Who Is More at Risk?

You may have a higher chance of getting an ingrown nail if you:

Are a teenager (nails grow faster)
Play sports regularly
Sweat heavily
Have diabetes
Have thick nails
Wear tight shoes daily

People with diabetes must be extra careful because infections can become serious quickly.

Home Remedies for Ingrown Nails

If the condition is mild, you can treat it at home.

1. Warm Salt Water Soak

Soak your foot in warm salt water for 15–20 minutes, 2–3 times daily.

Benefits:

Reduces swelling
Softens skin
Relieves pain
Prevents infection

2. Keep the Area Clean

Wash with mild soap and clean water daily. Dry properly.

3. Apply Antibiotic Cream

Use an over-the-counter antibiotic ointment and cover with a clean bandage.

4. Cotton Under the Nail (Carefully)

After soaking, gently place a small piece of clean cotton under the nail edge to lift it slightly.

⚠️ Do this very carefully to avoid injury.

5. Wear Open or Loose Shoes

Avoid tight footwear until healing is complete.

Medical Treatment Options

If home remedies do not work or infection develops, medical treatment is needed.

1. Prescription Antibiotics

If infection is present, a doctor may prescribe oral or topical antibiotics.

2. Partial Nail Removal

In severe cases, the doctor removes part of the nail under local anesthesia. This reduces pressure and allows healing.

The procedure is:

Quick
Safe
Usually painless (after anesthesia)

3. Permanent Nail Correction

If the problem keeps coming back, doctors may remove part of the nail root to stop that side from growing again.

This prevents future ingrown nails.

What Happens If You Ignore It?

Ignoring an ingrown nail can cause:

Severe infection
Abscess
Spreading infection
Skin overgrowth
Permanent nail damage

In diabetic patients, it can even lead to serious complications.

Early treatment is always better.

How Long Does It Take to Heal?

Mild case: 1–2 weeks
Moderate case: 2–4 weeks
After surgery: 2–3 weeks

Healing time depends on:

Severity
Infection
Care routine

How to Prevent Ingrown Nails

Prevention is very important.

1. Cut Nails Properly

Cut straight across
Do not cut too short
Do not round the edges

2. Wear Proper Shoes

Choose shoes that:

Fit comfortably
Have enough toe space
Do not squeeze toes

3. Keep Feet Clean and Dry

Wash daily and dry properly, especially between toes.

4. Avoid Nail Biting or Picking

Do not tear nails by hand.

5. Trim Nails Regularly

Do not let them grow too long.

When Should You See a Doctor?

See a doctor if:

Pain becomes severe
There is pus
Swelling increases
You have diabetes
The condition keeps returning

Do not try to cut deep or remove the nail yourself at home.

Ingrown Fingernails vs Toenails

Toenails are more commonly affected because:

Shoes create pressure
Toes face more trauma
Nails are thicker

Fingernails can also become ingrown but are less common.
