Ingrown Nails: Symptoms, Causes, Types, Diagnosis, and Treatments

Ingrown nails, medically referred to as onychocryptosis, are a common yet often painful condition where the edge or corner of a toenail—most frequently the big toe—grows into the soft flesh surrounding the nail. This seemingly minor issue can escalate into a significant health concern if left untreated, leading to infection, persistent pain, and even surgical intervention.

Whether you’re experiencing this condition or want to prevent it, understanding its causes, symptoms, types, diagnostic methods, and treatments is essential. This comprehensive guide explores everything you need to know about ingrown nails.

What Are Ingrown Nails?

Ingrown nails occur when the edge of a nail curves and grows into the surrounding skin. Although this condition can affect fingernails, it’s much more common in toenails, especially the big toe.

The inward growth irritates the skin, causing pain, redness, swelling, and sometimes infection. Ingrown nails are prevalent across all age groups but are especially common in teenagers and adults who wear tight footwear or engage in activities that stress the toes.

Symptoms of Ingrown Nails

The symptoms of ingrown nails usually develop gradually and can range from mild to severe depending on how deep the nail has grown into the skin. Common signs and symptoms include:

• Pain and tenderness along one or both sides of the nail
• Redness and swelling around the nail
• Increased warmth in the affected toe
• Pus or drainage, indicating infection
• Overgrowth of skin around the nail
• Difficulty walking or wearing shoes due to pain

In severe cases, especially when infection sets in, the symptoms can extend beyond the toe, requiring medical attention.

Causes of Ingrown Nails

Multiple factors contribute to the development of ingrown nails, some of which are behavioral while others are anatomical or medical.

1. Improper Nail Trimming

Cutting nails too short or rounding the edges can encourage the nail to grow into the skin.

2. Tight Footwear

Wearing shoes that crowd the toes increases pressure, pushing the nail into the surrounding skin.

3. Injury or Trauma

Stubbing your toe or repetitive pressure from activities like running or kicking can alter nail growth.

4. Poor Foot Hygiene

Failing to keep feet clean and dry can increase the risk of nail and skin infections that exacerbate ingrown nails.

5. Genetic Predisposition

Some individuals are naturally more prone to ingrown nails due to curved or fan-shaped nails.

6. Nail Disorders

Conditions such as fungal infections or psoriasis can distort nail shape, increasing the risk of ingrown nails.

Types of Ingrown Nails

Understanding the types of ingrown nails helps in choosing the appropriate treatment strategy.

1. Mild (Stage 1)

• Slight redness and pain
• No pus or major swelling

2. Moderate (Stage 2)

• Increased redness, swelling
• Pus discharge, more intense pain

3. Severe (Stage 3)

• Chronic infection
• Granulation tissue formation
• Possible abscess or cellulitis

Diagnosis of Ingrown Nails

Diagnosis is generally straightforward and involves a physical examination of the affected toe. In rare cases where infection has spread or a bone infection is suspected, the doctor may order:

• X-rays to check bone involvement
• Wound cultures to identify bacteria
• Blood tests if systemic infection is suspected

Doctors may also rule out other causes like paronychia (skin infection around the nail) or nail tumors.

Treatment Options for Ingrown Nails

Treatment depends on the severity of the condition. Options range from conservative care to surgical intervention.

Non-Surgical Treatments

• Soaking the foot in warm, soapy water 3–4 times a day
• Applying antibiotic ointment and bandaging the toe
• Wearing open-toed shoes or loose-fitting footwear
• Gently lifting the edge of the nail and placing cotton or dental floss underneath

Over-the-Counter Medications

• Pain relievers like acetaminophen or ibuprofen
• Topical antiseptics to prevent infection

Home Remedies and Self-Care Tips

If the ingrown nail is in its early stage and not infected, home treatment can be quite effective.

1. Warm Salt Soaks

• Add Epsom salt to warm water
• Soak the affected foot for 15–20 minutes
• Reduces swelling and draws out fluid

2. Apple Cider Vinegar

• Its anti-inflammatory and antiseptic properties may help
• Mix equal parts vinegar and water for foot soaking

3. Hydrogen Peroxide

• Helps in disinfecting the area
• Soak the toe in a hydrogen peroxide solution for 15 minutes

4. Essential Oils

• Tea tree oil has antibacterial properties
• Mix with carrier oil and apply to the toe

Note: These remedies are suitable for mild cases and should be discontinued if symptoms worsen.

Surgical and Medical Treatments

When conservative and home treatments fail, medical or surgical interventions may be required.

1. Partial Nail Avulsion

The ingrown portion of the nail is removed under local anesthesia.

2. Matrixectomy

The nail matrix (growth center) is partially or fully destroyed using chemicals or laser to prevent regrowth.

3. Total Nail Removal

In extreme or recurrent cases, the entire nail is removed.

4. Antibiotic Therapy

Oral antibiotics may be prescribed for infected ingrown nails, especially if cellulitis is present.

5. Cryotherapy or Laser

These methods destroy the nail root in chronic cases, preventing regrowth of the problematic portion.

Complications of Untreated Ingrown Nails

Neglecting an ingrown nail can lead to serious health problems, especially in people with diabetes or compromised immunity.

• Chronic infection
• Abscess formation
• Cellulitis (skin infection)
• Osteomyelitis (bone infection)
• Permanent nail deformity
• Tissue necrosis in extreme cases

Diabetic individuals must take extra precautions due to their slower healing and higher risk of infection.

Preventing Ingrown Nails

Prevention is always better than cure. Here are tips to avoid the development of ingrown nails:

1. Proper Nail Trimming

• Cut nails straight across
• Avoid rounding the corners
• Don’t cut nails too short

2. Wear Comfortable Footwear

Choose shoes with adequate space for your toes.

3. Maintain Foot Hygiene

Wash your feet daily, dry them thoroughly, and change socks regularly.

4. Avoid Repetitive Trauma

Use protective footwear during sports or heavy-duty work.

5. Monitor Nail Health

If you have curved nails or a history of ingrown nails, examine your toes regularly.

When to See a Doctor

You should consult a healthcare provider if:

• Pain or swelling worsens
• There’s persistent pus or drainage
• You have diabetes, nerve damage, or poor circulation
• The ingrown nail keeps recurring
• Over-the-counter treatments fail to resolve the issue

Conclusion

Ingrown nails may seem like a minor inconvenience, but they can quickly become a painful and persistent issue if not treated correctly. By understanding the causes, recognizing the symptoms early, and implementing preventive measures, you can significantly reduce your risk.

For mild cases, home care is often sufficient. However, don’t hesitate to seek medical help if you notice signs of infection or if the condition recurs frequently. With the right treatment and care, ingrown nails can be effectively managed and prevented.
