What is it? An ingrown toenail, or onychocryptosis, is a very common and painful condition where the edge or corner of the toenail grows into the soft flesh of the toe, usually affecting the big toe. This "digging in" of the nail plate acts as a foreign body, causing irritation, inflammation, and pain. If left untreated, the break in the skin allows bacteria to enter, which can lead to infection, significant swelling, and pus formation.

The nail can start to curl inwards along one or both sides (incurvated), or a small "spike" of nail can be left behind after cutting, which then grows straight into the skin. Ingrown toenails are highly prevalent in the UK, affecting people across all demographics, and are a frequent reason for seeking private podiatry care.

What are the symptoms? The early symptoms are often subtle:

• Tenderness or mild pain when pressure is applied to the side of the toe.
• Redness and slight swelling of the skin adjacent to the nail.

As the condition progresses, the symptoms become more severe, especially if an infection develops:

• Intense pain, which can be throbbing and made worse by any touch, including the weight of bedsheets.
• Marked redness, warmth, and significant swelling of the toe.
• The appearance of yellow, white, or green pus or discharge from the nail fold.
• Overgrowth of pink, 'beefy' granulation tissue, which bleeds easily.
• If infection is severe, the toe can become extremely swollen, red, and warm to the touch.

What causes it? A variety of factors can cause or contribute to an ingrown toenail:

• Improper Trimming: The most frequent cause is cutting the toenails too short or tapering the corners, rather than trimming them straight across. This encourages the nail to grow into the side folds of the skin.
• Tight Footwear: Wearing shoes or socks that are too tight, too narrow, or have a pointed toe box squeezes the toes, pressing the nail into the skin.
• Nail Trauma: Stubbing your toe, dropping a heavy object on it, or engaging in activities that cause repetitive impact (such as running or playing sports) can damage the nail, causing it to grow irregularly.
• Nail Shape/Genetics: Some individuals naturally have highly curved (fan-shaped or pincer) nails that are genetically predisposed to growing inward.
• Poor Hygiene: Excessive foot sweating can make the skin around the nails softer and more susceptible to penetration by the nail.

What are the treatment options? It is crucial not to attempt 'bathroom surgery' as this frequently leads to more severe infection and trauma. A podiatrist can provide effective and immediate relief, offering the following options based on the severity:

• Routine Management: For less severe cases, a podiatrist can painlessly trim or 'clear' the ingrowing section of the nail, smooth the rough edge, and apply a soothing dressing.
• Nail Surgery (Partial Nail Avulsion): This is a very common, highly successful, and permanent solution for chronic or severely infected ingrown toenails. It is a minor procedure carried out in the clinic under a local anaesthetic, ensuring you feel no pain.
  • The Procedure: The podiatrist removes the small sliver of the nail that is digging into the skin. The nail bed where the sliver was removed is then treated with a chemical (phenol) to stop that specific edge of the nail from ever growing back, maintaining the overall cosmetic appearance of the nail. The toe is then carefully dressed.
  • Post-Operative Care: We provide detailed instructions on how to care for your toe at home, and the healing process is typically very quick, allowing you to return to normal activities with minimal downtime.
• Antibiotic Advice: If the toe is infected, we can provide precise guidance on managing the infection. However, the definitive treatment involves removing the nail spike.
