That Splinter Won’t Come Out—What Should You Do?

Splinter Safety, Skin Protection & Infection Warning Signs

It starts as a tiny annoyance.

Maybe you were moving a wooden box, gardening, walking barefoot on a deck, or handling something rough when suddenly you felt a sharp sting.

You look down and see it: a splinter stuck beneath your skin.

Many superficial splinters are minor. But when one is deeply embedded, breaks beneath the skin, becomes increasingly painful, or simply refuses to come out easily, repeatedly digging at it can turn a small problem into a much bigger one.

Wood, thorns, glass fragments, metal pieces, and other foreign materials can sometimes become lodged in the skin.

The safest response depends on what entered the skin, how deeply it is embedded, where it is located, and whether signs of infection or tissue injury are developing.

This UrgentCare2Go PSA explains how to handle a stubborn splinter safely—and when it's time to stop trying at home.

What Is A Splinter?

A splinter is a small foreign object that becomes embedded in or beneath the skin.

Common materials include:

Wood
Plant thorns
Fiberglass
Tiny metal fragments
Small glass fragments
Plastic
Other debris

Some sit just beneath the skin's surface and are easy to see.

Others may:

Break into smaller pieces
Penetrate more deeply
Become difficult to locate
Sit beneath thick skin
Enter near a joint, nail, eye, or other sensitive area

Those situations may require professional evaluation.

Why Can Such A Tiny Splinter Hurt So Much?

Your skin contains many sensory nerves.

Even a small foreign object can irritate surrounding tissue and cause:

Sharp pain
Tenderness
Stinging
Redness
Mild swelling
Pain when pressure is applied

Movement can make the discomfort more noticeable when the splinter is located in a finger, palm, foot, or near a joint.

What Should You Do First?

For a small, superficial splinter without concerning symptoms, start by protecting the area.

Wash Your Hands

Clean hands help reduce the chance of introducing bacteria into the skin.

Gently Clean The Area

Use soap and clean running water around the affected skin.

Look Carefully

Determine whether the object is:

Clearly visible
Superficial
Protruding from the skin
Deeply embedded
Broken beneath the surface

Good lighting can help.

Don't Immediately Start Digging

If the splinter isn't easily accessible, repeatedly poking at the skin may cause more tissue damage.

When A Superficial Splinter May Be Easier To Remove

A tiny splinter may sometimes be manageable at home when:

It is very close to the surface.
One end is clearly visible.
It isn't near the eye or another sensitive structure.
It isn't deeply embedded.
There isn't significant bleeding.
There aren't signs of infection.
Removal doesn't require cutting deeply into the skin.

If an object doesn't come out easily, stop rather than escalating to aggressive digging or cutting.

Keep Everything Clean

If you attempt to manage a minor superficial splinter, cleanliness matters.

Wash your hands and clean the affected area first.

Avoid using:

Dirty tweezers
Unclean needles
Rusty tools
Pocket knives
Household blades
Other improvised sharp objects

Breaking the skin further with contaminated equipment can increase the risk of infection.

Don't Keep Digging

This is one of the most important rules.

If you can't easily reach the splinter, repeatedly digging through the skin may:

Push it deeper
Break it into smaller pieces
Increase bleeding
Damage surrounding tissue
Introduce bacteria
Increase pain
Make professional removal more difficult

A tiny splinter doesn't justify creating a much larger wound.

Don't Cut Your Skin Open At Home

If a foreign object is beneath the surface, don't use a razor blade, knife, scissors, or another sharp household object to cut the skin open.

Professional removal may require:

Proper lighting
Sterile or appropriate medical instruments
Local anesthesia
Wound exploration
Imaging
Additional treatment

These are very different from trying to perform a procedure on yourself at home.

What If The Splinter Breaks?

Sometimes the visible portion comes out while another piece remains under the skin.

If that happens:

Don't panic.
Don't aggressively squeeze the area.
Don't repeatedly puncture the skin trying to find the fragment.
Monitor for increasing pain, redness, or swelling.
Seek professional evaluation if a piece appears to remain embedded or symptoms worsen.

Wood and other organic material can sometimes provoke inflammation when retained in the skin.

What About A Splinter Under A Fingernail?

Splinters beneath the nail can be particularly painful and difficult to access.

Avoid aggressively cutting away large portions of the nail or digging deeply underneath it.

Professional evaluation may be appropriate when:

The splinter is deeply embedded.
Pain is significant.
Much of the object is underneath the nail.
You cannot reach it safely.
Bleeding is significant.
Infection develops.

What About Glass?

Glass deserves extra caution.

Tiny glass fragments may be difficult to see and may break into additional pieces.

Don't blindly dig into the skin looking for glass.

Seek professional evaluation when:

You suspect glass remains embedded.
The wound is deep.
Walking or movement causes sharp pain.
The fragment can't be easily seen.
There is significant bleeding.
The injury occurred near an important structure.

Imaging may sometimes be needed to locate certain foreign bodies.

What About Metal?

Metal fragments can also become embedded in the skin during:

Construction
Mechanical work
Grinding
Cutting
Home repairs
Industrial work

High-speed metal injuries deserve particular caution because a fragment may penetrate more deeply than expected.

Any suspected metal fragment involving the eye requires prompt specialized medical evaluation.

Don't attempt to remove an embedded object from the eye yourself.

Never Remove An Object Embedded In The Eye Yourself

An eye injury is not the same as an ordinary splinter.

If an object appears embedded in the eye:

Do not pull it out.
Do not press on the eye.
Do not rub the eye.
Do not attempt to dig around the object.
Seek emergency or specialized eye care promptly.

Significant eye injuries can threaten vision.

What If A Large Object Is Stuck In The Body?

A large or deeply penetrating object should not be pulled out at home.

Removing it may worsen bleeding or tissue damage.

For a serious penetrating injury:

Don't remove the embedded object.
Avoid unnecessary movement of the object.
Seek emergency medical care.

Call 911 when the injury is severe or life-threatening.

Can A Splinter Become Infected?

Yes.

Any break in the skin can provide a pathway for bacteria.

Watch for:

Increasing redness
Increasing warmth
Worsening swelling
Increasing pain
Pus or cloudy drainage
Red streaking
Fever
Worsening tenderness

These symptoms deserve medical evaluation.

Don't Squeeze Pus Out Yourself

If the area becomes swollen and appears to contain pus, don't aggressively squeeze, cut, or puncture it.

A developing skin infection or abscess may require professional evaluation and treatment.

Attempting to drain it yourself can:

Damage tissue
Spread infection
Introduce additional bacteria
Delay appropriate treatment

Why Red Streaks Matter

Redness immediately around an irritated spot may occur for several reasons.

However, red streaking extending away from a wound, particularly when accompanied by increasing pain, warmth, swelling, or fever, deserves prompt medical evaluation.

Don't wait for a worsening infection to become severe before seeking care.

What About Tetanus?

Puncture wounds and certain contaminated wounds may raise questions about tetanus vaccination.

Your need for a tetanus-containing vaccine depends on factors such as:

The type of wound
How contaminated it was
Your vaccination history
When your most recent tetanus-containing vaccine was given
Whether your primary vaccine series was completed

If you're unsure of your vaccination status, contact a healthcare professional for guidance.

It's Not Simply About “Rust”

People often associate tetanus exclusively with rusty nails.

That's misleading.

The concern is wound contamination and exposure to tetanus-causing bacteria, not rust itself.

A dirty puncture wound from another object may also require attention to tetanus protection.

Splinters In The Foot Need Extra Attention

A splinter in the foot may become particularly uncomfortable because body weight repeatedly presses on the area.

Seek evaluation if:

Walking becomes painful.
You believe part of the object remains embedded.
The puncture is deep.
Swelling is increasing.
Redness is spreading.
Drainage develops.
You have reduced sensation in your feet.

Avoid repeatedly walking barefoot on a painful puncture site.

Diabetes Or Reduced Sensation Changes The Situation

People with reduced sensation, impaired circulation, or certain chronic medical conditions may not feel foot injuries normally.

A seemingly minor puncture or embedded object may deserve earlier professional evaluation in these situations.

Regularly inspect the affected area and don't rely on pain alone to determine whether a wound is becoming more serious.

What If You Can't See The Splinter Anymore?

Sometimes pain remains even though the object isn't visible.

Possible explanations include:

A small fragment remains beneath the skin.
The object broke.
The area is simply irritated after removal.
Inflammation has developed.
Another injury occurred.

If persistent focal pain continues or symptoms worsen, seek medical evaluation rather than repeatedly digging through the skin.

When Professional Evaluation Is Recommended

Consider medical evaluation when:

The splinter won't come out easily.
It is deeply embedded.
Part of it broke off.
You suspect retained glass or metal.
The wound is significantly painful.
The object is beneath a nail.
The injury is near a joint.
Walking becomes difficult.
Redness or swelling is increasing.
Drainage develops.
You are unsure about tetanus protection.
You have reduced sensation or circulation.
You aren't sure whether the entire object was removed.

Some foreign bodies require imaging or a procedure for safe removal.

When To Stop Trying At Home

STOP if removal requires you to:

Dig deeply
Cut the skin
Repeatedly puncture the area
Squeeze aggressively
Use significant force
Explore blindly for an object you can't see

At that point, the risk of creating additional injury may outweigh the benefit of continuing.

When Prompt Medical Care Is Needed

Seek prompt professional care for:

A deeply embedded object
Suspected retained glass
High-speed metal fragments
Increasing redness or warmth
Rapidly increasing swelling
Pus or drainage
Red streaking
Fever
Significant pain
Numbness or weakness
Difficulty moving a finger or limb
A foreign body near the eye
Significant puncture wounds
Worsening symptoms after attempted removal

The appropriate location for care depends on the severity and location of the injury.

When To Call 911

🚨 Call 911 For A Serious Emergency

Call 911 for:

Severe uncontrolled bleeding
A major penetrating injury
A large embedded object associated with serious trauma
Loss of consciousness
Signs of shock
Severe breathing difficulty
Multiple serious injuries
Another life-threatening emergency

Don't remove a large penetrating object yourself while waiting for emergency assistance.

Frequently Asked Questions

Should I keep digging if a splinter won't come out?

No. If a splinter isn't easily accessible, repeated digging may push it deeper, break it, damage tissue, or introduce bacteria.

Can I cut my skin open to get a splinter?

Don't use household blades or other sharp objects to cut deeply into your skin. A difficult foreign body may require professional removal.

What if part of the splinter breaks off?

Stop aggressive attempts to retrieve it. Seek evaluation if a fragment appears to remain or pain, redness, or swelling worsens.

Can a splinter cause an infection?

Yes. Increasing redness, warmth, swelling, pain, drainage, red streaking, or fever can indicate infection.

Should I squeeze pus around a splinter?

No. Don't aggressively squeeze, cut, or puncture a suspected infection yourself.

Do rusty splinters cause tetanus?

Rust itself isn't the cause of tetanus. Certain contaminated wounds can create tetanus risk depending on the wound and your vaccination history.

What if glass is stuck in my foot?

Don't blindly dig for it. Persistent sharp pain or suspected retained glass deserves professional evaluation.

Can I remove something embedded in my eye?

No. Do not attempt to remove an object embedded in the eye. Seek prompt emergency or specialized eye care.

When is a splinter an emergency?

A typical superficial splinter usually isn't an emergency. Severe bleeding, serious penetrating trauma, a large embedded object, shock, or another life-threatening injury requires emergency care.
