Ingrown Fingernail - Symptoms, Causes, and Treatment

What Does Ingrown Fingernail Mean?

Ever had a fingertip so sore you couldn’t even tap your phone screen? Sometimes, your fingernail may curve and grow into the surrounding skin. This is called an ingrown fingernail. Though more common in toes, fingernails can also become ingrown, especially if you bite your nails, trim them improperly, or injure your fingers.

An ingrown fingernail happens when the nail’s edge digs into the surrounding skin—a common and often painful issue. It can cause pain, swelling, and sometimes infection. This article explains what causes ingrown fingernails, what symptoms to look for, how they are diagnosed, possible problems if not treated, and ways to manage or prevent them. Early treatment and good nail care can help avoid complications.

What Are the Causes of Ingrown Fingernails?

Can you get ingrown fingernails? Yes, several things can cause a fingernail to grow into the skin:

• Incorrect Nail Cutting: Cutting nails too short or rounding the edges too much can make them grow inward.

• Nail Biting or Picking: Biting nails or picking at them damages the nail and the nearby skin.

• Injury to the Nail: Hitting or jamming your finger can change how the nail grows.

• Tight Gloves or Repeated Pressure: Wearing tight gloves for long hours or pressing fingers against surfaces (like typing or playing instruments) can lead to changes in nail growth.

• Fungal Infections: These can make the nail thick, brittle, or misshapen, increasing the chance of ingrowth.

• Genetics: Some people naturally have curved nails or thicker nail folds that make them more likely to develop ingrown nails.

• Excessive Moisture: Wet hands soften the skin around the nails, making it easier for nails to grow into the skin.

• Naturally Curved or Thick Nails: Genetics or age can cause nail shapes that predispose them to grow into the skin.

What Are the Symptoms of Ingrown Fingernails?

You may notice these symptoms:

• Pain when pressing the side of the nail may be an early sign of an ingrown fingernail.

• Throbbing pain from an ingrown fingernail and tenderness on the nail’s edge.

• Redness and swelling around the nail.

• Warmth in the area.

• Pus or fluid discharge (if infected).

• Difficulty using the finger normally.

• Hard skin or extra tissue growth near the nail.

If the ingrown fingernail is infected, the pain may increase, and the skin might become more swollen or ooze pus.

How Is an Ingrown Fingernail Diagnosed?

Doctors usually diagnose it just by looking at the nail. They may:

• Check the nail for signs of swelling, redness, or infection.

• Gently press the area to see how tender it is.

• Ask about your nail care habits or any recent injury.

Tests are rarely needed. However, if the infection is deep or spreading, a sample of the pus might be taken to check for bacteria.

What Are the Potential Complications of Ingrown Fingernails?

If untreated, an ingrown fingernail can lead to:

• Infection: The skin can get infected, leading to pus, warmth, and more swelling.

• Abscess Formation: A collection of pus, an abscess, may form under the skin.

• Chronic Ingrown Nail: The nail may continue to grow incorrectly if the root is affected.

• Nail Loss or Deformity: Repeated problems may change the shape of the nail permanently.

• Spread of Infection: In rare cases, infection from an ingrown fingernail can spread to nearby tissues or even the bone (especially in people with diabetes or weak immunity).

• Bone Infection: Also known as osteomyelitis in severe or unmanaged cases.

How to Treat Ingrown Fingernails?

Now, you might wonder how to fix an ingrown fingernail. You can often manage it at home if you catch it early. Ingrown fingernail treatment involves:

1. Home Care (Mild Cases):

Ingrown fingernail self-care tips are:

• Soak your finger in warm, soapy, or saline water (10 to 20 minutes, 3 to 4 times a day).

• Gently lift the nail with clean cotton, gauze, or waxed dental floss to help proper nail growth.

• Apply antibiotic ointment (e.g., Neosporin or Polymyxin, Neomycin) and cover with a clean bandage.

• Use NSAIDs (non-steroidal anti-inflammatory drugs) such as Ibuprofen or Acetaminophen to ease pain and reduce inflammation.

• Keep it clean and dry, especially between treatments.

• Using a cold compress can bring down swelling and ease the ache.

Important: Avoid cutting, digging, or “bathroom surgery”—this can worsen the condition.

2. When to See a Doctor:

Seek medical care if you experience:

• Increasing pain or swelling after two to three days of home care.

• Signs of infection include pus, redness, warmth, fever, or streaking skin.

• Chronic recurrence or underlying health conditions (e.g., diabetes).

3. Non-invasive Medical Treatments

• Abscess Drainage: If an abscess forms, a doctor may drain it.

• Partial Nail Removal With Splinting: Local anesthesia is used to lift or remove the ingrown edge and insert a splint, preventing regrowth into the skin.

• Topical or Oral Antibiotics: Prescribed when infection is present.

4. Surgical Options

Although rare for fingernails, procedures are available when needed:

• Partial Nail Avulsion and Chemical Matricectomy: Removes the ingrown portion and applies phenol or sodium hydroxide to prevent regrowth.

• Complete Nail Removal: Typically used only in severe or recurrent cases

• Electrocautery or Laser Ablation: Used to remove the nail matrix to prevent regrowth

These procedures are effective but come with recovery time and possible narrowing of the nail.

In chronic cases, doctors may destroy the nail root (matricectomy) using chemicals or a laser to stop that part of the nail from growing again.

How to Prevent Ingrown Fingernails?

Preventing ingrown nails is simple with good nail care:

• Trim Nails Properly: Cut straight across and avoid rounding the edges too much.

• Avoid Nail Biting or Picking: Keep nails clean and avoid damaging them.

• Wear Proper Gloves: Use gloves when doing work that puts pressure on the fingers.

• Avoid Injuries: Be careful when playing sports or using tools.

• Treat Fungal Infections Early: Keep your hands dry and use antifungal creams if needed.

• Moisturize: Dry skin can crack easily, increasing the chance of nail problems. Use hand cream regularly.

• Keep Them Clean and Dry: Moist skin softens and increases risk.

When to Seek Medical Advice?

See a doctor if:

• Pain becomes severe or doesn't improve in two to three days.

• You see an ingrown fingernail with pus or signs of infection (redness, warmth, swelling).

• You have frequent ingrown nails.

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

• Home treatment doesn’t work.

Early care prevents long-term damage or serious infections.

Conclusion

Ingrown fingernails can hurt, but they are common. This happens when your nail grows into the skin instead of straight out. It can happen if you cut your nails too short, hurt your finger, or get an infection.

The good news is that you can treat it at home if you catch it early. Keep your nails clean, cut them the right way, and try not to hurt your fingers. This can help stop the problem from coming back.

But if your finger gets redder, swollen, or painful, you should see a doctor. They can help you feel better and stop the problem from getting worse.
