An ingrown toenail is one of the most common and painful foot conditions that people experience. It occurs when the edge or corner of a toenail grows downward into the surrounding skin instead of over it, causing persistent discomfort, swelling, redness, and in many cases, infection. While the big toe is most frequently affected, any toenail can become ingrown.

What Is an Ingrown Toenail?
An ingrown toenail, medically known as onychocryptosis, develops when the edge of the nail curves and grows into the soft tissue surrounding the toe. This creates a sharp pressure point that irritates the skin, leading to inflammation, pain, and sometimes a break in the skin that allows bacteria to enter. Left untreated, the condition typically worsens over time, and what begins as a minor annoyance can progress into a serious infection requiring more intensive treatment.
Ingrown toenails are extremely common. Studies estimate that approximately one in twenty people will develop an ingrown toenail at some point in their lives, making it one of the most frequently treated conditions in podiatric medicine. People of all ages can be affected, from children and teenagers to adults and seniors.
What Causes an Ingrown Toenail?
Several factors can contribute to the development of an ingrown toenail. Understanding the cause is an important part of both treating the current problem and preventing it from recurring.
- Improper nail trimming
- Tight or narrow footwear
- Genetic nail shape
- Foot trauma
- Poor foot hygiene
- Nail conditions
- Structural foot problems
Symptoms of an Ingrown Toenail
Ingrown toenails present with a recognizable set of symptoms that typically worsen as the condition progresses. Recognizing these signs early allows for simpler, less invasive treatment.
Early Stage Symptoms
- Pain or tenderness along one or both sides of the toenail
- Slight redness or pinkness of the skin bordering the nail
- Mild swelling near the nail edge
- Sensitivity when pressure is applied to the toe
Moderate Stage Symptoms
- Increased swelling and redness around the nail
- Skin beginning to grow over the nail edge
- Persistent pain that makes wearing shoes uncomfortable
- A feeling of warmth in the affected toe
Advanced Stage Symptoms
- Pus or watery discharge draining from the affected area
- A foul odor coming from the toe
- Bright red skin that is hot to the touch
- Tissue overgrowth around the nail creating a raised, bulging appearance
- Difficulty walking or bearing weight on the foot
- Fever in rare cases, indicating a spreading infection
| Important: If you notice any discharge, spreading redness, or warmth extending beyond the toe, seek professional care immediately. These are signs of infection that can become serious if left untreated, particularly in patients with diabetes, poor circulation, or a compromised immune system. |
When Should You See a Doctor?
Not every ingrown toenail requires a visit to the doctor, but many do. Home remedies can sometimes manage mild cases in otherwise healthy individuals, but professional care is necessary in the following situations.
Seek Professional Care If You Experience Any of the Following
- Pain that persists or worsens despite several days of home treatment
- Any sign of infection, including pus, increasing redness, warmth, or swelling
- A toenail that has become ingrown more than once on the same toe
- Skin growing visibly over the nail edge
- Difficulty walking, wearing shoes, or carrying out daily activities
- A toenail that appears to be causing bleeding or open wounds around the nail
See Us Immediately If You Have Any of the Following Conditions
- Diabetes
- Peripheral vascular disease or poor circulation
- Nerve damage in the feet
- A weakened immune system
| Patients with diabetes or compromised circulation should never attempt to treat an ingrown toenail at home. Even a minor infection in a diabetic foot can progress rapidly and lead to serious complications. Please contact our office at the first sign of any nail problem. |
