Paronychia is inflammation of the skin around a fingernail or toenail.

There are two general patterns.

Acute paronychia develops relatively quickly, often after the protective skin around the nail has been damaged and bacteria enter the area.

Chronic paronychia lasts longer or repeatedly returns and is often associated with ongoing irritation, moisture, or inflammation around the nail.

Common symptoms include:

• Redness

• Swelling

• Tenderness

• Throbbing pain

• Warmth

• Pus or fluid near the nail

• Changes in the surrounding cuticle

You don't need a dramatic injury for it to happen.

Sometimes all it takes is one tiny break in the skin.

Cuticles aren't just extra skin waiting to be cut off.

They help create a protective seal between the nail and surrounding skin.

Think of that seal as a tiny barrier.

When you:

• Bite your nails

• Pull off a hangnail

• Pick at your cuticles

• Cut the cuticle aggressively

• Have nail work performed

• Injure the skin around the nail

you can create a small opening.

Bacteria or other microorganisms may then enter the damaged skin and cause inflammation or infection.

That's why a tiny hangnail can sometimes turn into a surprisingly painful finger.

Several things can cause inflammation around a nail.

Hangnails and Picking

Pulling a hangnail can tear healthy skin along with it, leaving an opening for bacteria.

Nail Biting

Biting damages the skin barrier and repeatedly exposes the area to moisture and microorganisms from the mouth.

Manicures and Artificial Nails

Cutting or pushing the cuticles aggressively can damage the protective barrier.

Artificial nails, gels, adhesives, and nail products can also contribute to irritation or allergic contact dermatitis in some people.

Frequent Water Exposure

Repeatedly having wet hands can weaken and irritate the skin around the nails.

This may affect people who frequently wash dishes, clean, work with food, or wash their hands throughout the day.

Chemicals and Cleaning Products

Detergents, disinfectants, solvents, and other products can irritate the skin and contribute to chronic inflammation.

Early on, it can be difficult to tell.

Mild irritation may cause redness, dryness, cracking, and tenderness.

An infection becomes more concerning when symptoms include:

• Increasing pain

• Throbbing

• Warmth

• Worsening swelling

• Pus

• A pocket of fluid beside the nail

• Redness that continues spreading

A small collection of pus can sometimes form an abscess.

Once an abscess develops, simply putting antibiotic ointment on the surface may not be enough. The area may need to be evaluated to determine whether drainage or other treatment is necessary.

Pus changes the conversation.

If you see a collection of fluid around the nail, don't squeeze, puncture, or cut it open yourself.

If the skin around several nails stays red, swollen, or irritated for weeks, the problem may be different from a one-time bacterial infection.

Repeated exposure to water, chemicals, detergents, and irritants can damage the skin barrier around the nail.

Conditions such as eczema or contact dermatitis can contribute as well.

Some people may also react to nail cosmetics or chemicals used in artificial or gel nails.

The clue is often the pattern.

One suddenly painful, swollen nail after pulling a hangnail may suggest an acute problem.

Several irritated nail folds that repeatedly flare may point toward ongoing exposure or chronic inflammation.

Treating the immediate symptoms without addressing the trigger means the problem may keep coming back.

For mild symptoms without significant pus or spreading redness, simple care may help.

Consider:

• Soaking the affected finger in warm water

• Keeping the area clean

• Drying your hands thoroughly

• Avoiding picking, biting, or cutting the affected skin

• Avoiding manicures or artificial nail products until the area heals

• Protecting your hands from repeated water and chemical exposure

• Using gloves when working with cleaning products

If you have a hangnail, don't rip it off.

Carefully trimming loose skin with clean nail clippers is less likely to create a larger tear.

And don't try to create your own drainage procedure with a needle.

A painful finger is frustrating.

A deeper infection caused by trying to treat it yourself is worse.

Consider an evaluation if:

• Pain or swelling is getting worse.

• You see pus or a pocket of fluid.

• Redness is spreading.

• The finger feels increasingly warm.

• Home care isn't helping.

• Symptoms repeatedly return.

• Several nails are affected.

• The nail itself begins changing.

• You have diabetes, poor circulation, or a weakened immune system.

• You're unsure whether you're dealing with infection, dermatitis, or another nail condition.

Treatment depends on what's causing the inflammation.

Some infections may require prescription medication.

An abscess may need drainage.

Chronic irritation may require a completely different approach.

That's why identifying the cause matters.

Don't ignore symptoms that suggest an infection may be spreading or becoming more serious.

Seek prompt medical attention for:

• Rapidly spreading redness or swelling

• Severe or worsening pain

• Fever or chills

• Red streaking moving up the finger or hand

• Significant difficulty moving the finger

• Severe swelling of the finger

• Numbness or changes in color

• Infection after a serious puncture or injury

• Rapidly worsening symptoms in someone with diabetes or a weakened immune system

Not every painful nail needs urgent care.

But infections involving the hand can become more serious if they spread into deeper tissues.

A worsening finger infection deserves attention—not another few days of squeezing it to see what happens.

In many cases, yes.

Through CallOnDoc's secure asynchronous online medical evaluation, you can provide information about:

• When the symptoms started

• Which nail is affected

• Redness and swelling

• Pain or throbbing

• Whether pus or drainage is present

• Nail biting or picking

• Recent manicures or artificial nails

• Injuries or hangnails

• Water or chemical exposure

• Medical conditions that may affect healing

• Treatments you've already tried

When appropriate, clear photos can also help a provider evaluate the affected area.

A licensed healthcare provider can review your symptoms and determine whether the condition may be appropriate for online treatment.

For eligible patients, prescription treatment may be available when clinically appropriate.

If there appears to be an abscess that needs drainage, a deeper infection, significant injury, or another condition requiring a hands-on examination, your provider may recommend in-person care.

Red, Swollen, and Getting More Painful? Don't Wait for It to Get Worse.

That tiny sore spot beside your nail may be simple irritation.

But if it's becoming more swollen, more painful, warm, or filled with pus, it may need more than home care.

Complete a CallOnDoc medical evaluation from home and let a licensed provider review your symptoms and determine the appropriate next step.

Because when an infection is developing around your nail, treating it early may help keep a small problem from becoming a much bigger one.

Why is the skin around my fingernail red and painful?

Common causes include a hangnail, nail biting, cuticle damage, irritation, manicures, frequent water exposure, or paronychia.

What is paronychia?

Paronychia is inflammation or infection of the skin around a fingernail or toenail. It may cause redness, swelling, tenderness, warmth, and sometimes pus.

Can a hangnail cause an infection?

Yes. Pulling or tearing a hangnail can create a small break in the skin that allows bacteria to enter.

Should I squeeze pus from around my fingernail?

No. Don't puncture, squeeze, or cut open a suspected abscess yourself. A healthcare provider can determine whether drainage is necessary.

Can manicures cause paronychia?

They can. Cutting or damaging the cuticle can disrupt the protective barrier around the nail. Nail products may also cause irritation or allergic reactions in some people.

Why do several of my cuticles stay red and irritated?

Repeated water exposure, cleaning products, nail products, eczema, contact dermatitis, and chronic paronychia can all contribute to ongoing inflammation around multiple nails.

When should I see a provider for an infected fingernail?

Seek evaluation if pain, swelling, or redness is worsening; pus develops; redness begins spreading; symptoms don't improve; or you have medical conditions that increase the risk of complications.

A red, swollen spot beside your fingernail can look like a tiny problem.

It doesn't always feel tiny.

The skin around your nails provides an important protective barrier, and something as simple as pulling a hangnail or picking at a cuticle can create an opening for irritation or infection.

If symptoms are mild, protect the area and give the skin a chance to heal.

But pay attention to what happens next.

More pain.

More swelling.

Pus.

Spreading redness.

Those are signs that it's time to stop treating it like “just a hangnail.”

And if the problem keeps happening around multiple nails, look beyond infection and consider what your hands are repeatedly exposed to.

Sometimes the key to healthier nails isn't what's happening to the nail itself.

It's protecting the skin around it.
