Introduction
You glance down at your feet and notice that one or more toenails looks different than it used to. Maybe the color has changed to yellow or brown. Maybe the nail has become thick, brittle, or crumbly at the edges. Maybe there is an odor that was not there before. If any of this sounds familiar, you may be dealing with a fungal nail infection, a condition that is far more common than most people realize and one that is far more treatable than many assume.
At FitFeet, our podiatrists regularly help patients across Merrick, Williamsburg, and Brighton Beach identify and successfully treat fungal nail infections. If your nails do not look or feel the way they should, do not wait for the problem to worsen. Schedule an appointment with FitFeet today and get an accurate diagnosis from a trusted podiatry team.
What Is a Fungal Nail Infection?
A fungal nail infection, known medically as onychomycosis, is an infection of one or more nails caused by fungal organisms. These organisms, most commonly dermatophytes but occasionally yeasts or non-dermatophyte molds, thrive in warm, moist environments and can enter the nail through small cuts, separations between the nail and the nail bed, or other vulnerable areas.
Toenails are significantly more susceptible to fungal infection than fingernails because the feet spend so much time enclosed in shoes and socks, creating the warm, humid conditions that fungi prefer. The condition is extremely common, affecting roughly 10 percent of the general population, with rates increasing significantly with age.
How to Tell If You Have a Fungal Nail Infection
One of the most important steps in getting effective treatment is recognizing the signs of a fungal nail infection early. The longer the infection is present without treatment, the more entrenched it becomes and the harder it is to clear. Here is what to look for:
Discoloration of the Nail
One of the earliest and most noticeable signs of a fungal nail infection is a change in nail color. The affected nail may turn yellow, brown, white, or even green in some cases. The discoloration often begins at the tip of the nail and works its way toward the base as the infection progresses. In some cases, white patches or spots may appear on the surface of the nail.
Thickening of the Nail
As the fungus takes hold within the nail structure, the nail often becomes thicker than normal. A nail that was once easy to trim may become difficult to cut without strong clippers or professional tools. Thickened nails can become uncomfortable or painful, particularly when wearing closed shoes, because they press against the toe box with every step.
Brittle, Crumbly, or Ragged Edges
Fungal infections break down the keratin that gives nails their structure. As a result, affected nails often become brittle, crumbly, or prone to breaking or chipping. The edges of the nail may look jagged, powdery, or uneven rather than smooth and firm.
Distorted Nail Shape
A nail affected by onychomycosis may begin to change shape, curling, thickening unevenly, or growing in an abnormal direction. In more advanced cases, the nail may separate from the nail bed entirely, a process called onycholysis, leaving a space that can trap debris, moisture, and additional fungal organisms.
Darkening Under the Nail
As debris builds up between the nail and the nail bed, a dark or discolored area may appear under the nail. This buildup, known as subungual hyperkeratosis, can also cause the nail to appear elevated or detached from the toe.
An Unpleasant Odor
Fungal nail infections can produce a distinctive, unpleasant odor resulting from the fungal byproducts and the accumulation of debris beneath the nail. While not always present, this symptom is a strong indicator that the nail warrants professional evaluation.
Lack of Nail Luster
Healthy nails have a certain degree of shine and translucency. A fungally infected nail often loses this quality, appearing dull, opaque, or chalky. This is one of the subtler early signs that something is developing beneath the nail surface.
What Causes Fungal Nail Infections?
Fungal nail infections develop when fungi come into contact with the nail and find conditions that allow them to grow. Several factors increase susceptibility:
- Walking barefoot in communal areas such as locker rooms, pool decks, and nail salons
- Wearing tight, non-breathable shoes that create a warm, moist environment
- Keeping feet damp for extended periods without proper drying
- Having a nail injury or a history of athlete’s foot, which can spread to the nails
- Age, as nails become more porous and grow more slowly over time, making them easier for fungi to colonize
- Reduced circulation, which is common in people with diabetes or peripheral vascular disease
- A weakened immune system, which makes it harder for the body to fight off fungal organisms
- Wearing the same pair of shoes every day without allowing them to dry out between wears
Conditions That Can Be Mistaken for Nail Fungus
Not every nail that looks abnormal has a fungal infection. Several other conditions can produce similar signs, including:
- Psoriasis of the nail, which can cause pitting, thickening, and discoloration
- Nail trauma, which can produce bruising, discoloration, and nail separation
- Lichen planus, an inflammatory condition that can affect the nails
- Yellow nail syndrome, associated with lymphatic conditions
- Bacterial nail infections
This is why it is essential to have your nail evaluated by a podiatrist at FitFeet rather than self-treating based on appearance alone. An incorrect self-diagnosis can mean weeks or months of ineffective treatment and continued nail damage.

When to See a Podiatrist for a Fungal Nail Infection
Fungal nail infections are rarely a medical emergency, but they are also not a problem that typically resolves on its own. They tend to worsen over time and can spread to other nails or even to the skin of the foot. You should schedule an appointment at FitFeet when:
- You notice any of the signs described above in one or more nails
- An over-the-counter antifungal treatment has not produced noticeable improvement after several weeks
- The nail is causing pain, pressure, or discomfort
- You have diabetes or a compromised immune system, in which case nail infections should always be evaluated promptly
- The affected nail has separated from the nail bed or become difficult to manage
How FitFeet Diagnoses Fungal Nail Infections
At our offices in Merrick, Williamsburg, and Brighton Beach, the diagnostic process for fungal nail infections is straightforward and precise. Your podiatrist will perform a visual examination of the affected nail and may take a small sample of nail clippings or debris from beneath the nail for laboratory analysis.
Lab testing, known as nail culture or PAS staining, confirms the presence of a fungal organism and identifies the specific type responsible for the infection. This information is important because it guides the selection of the most effective treatment. Treating a nail condition that turns out not to be fungal, or using the wrong type of antifungal for the organism present, leads to treatment failure and ongoing nail damage.
Treatment Options for Fungal Nail Infections at FitFeet
FitFeet offers a range of effective, evidence-based treatment options for fungal nail infections. The right approach depends on the severity of the infection, the number of nails affected, your overall health, and other individual factors.
Topical Antifungal Treatments
Prescription-strength topical antifungals are applied directly to the nail and the surrounding skin. These are most effective for mild to moderate infections and for patients who cannot take oral medications. Modern prescription topical antifungals penetrate the nail plate more effectively than over-the-counter products and are applied as part of a structured treatment regimen.
Oral Antifungal Medications
Oral antifungal medications, such as terbinafine or itraconazole, are considered the most effective pharmaceutical treatment for established fungal nail infections. These medications work systemically, reaching the nail through the bloodstream. Treatment typically lasts several months, and the nail may take up to a year to grow out completely clear. Baseline lab work may be recommended before starting oral antifungals to ensure the treatment is safe for you.
Laser Therapy
Laser treatment for fungal nail infections is a modern, non-invasive option that uses targeted light energy to destroy fungal organisms within the nail without harming the surrounding tissue. It requires no medications and has no systemic side effects. Multiple sessions are typically needed, and results develop as the nail grows out.
Nail Debridement
Your FitFeet podiatrist may perform debridement, the reduction or removal of thickened, infected nail tissue, to improve both comfort and the penetration of topical treatments. This is often done in combination with other therapies as part of a comprehensive approach.
What to Expect During and After Treatment
Fungal nail infections require patience. Even when the infection is fully cleared by medication or laser therapy, the visual improvement of the nail happens gradually as the new, healthy nail grows out. Toenails grow approximately one millimeter per month, so full visual clearing of a toenail infection can take nine to twelve months.
Throughout your treatment, FitFeet will monitor your progress and make adjustments as needed. It is important to continue treatment for the full recommended course even if the nail starts to look better earlier, as stopping too soon can allow the infection to return.
Tips for Preventing Fungal Nail Infections
- Keep feet clean and thoroughly dry, particularly between the toes
- Wear moisture-wicking socks and breathable footwear
- Rotate your shoes so each pair has time to dry out fully between wears
- Wear waterproof sandals or flip-flops in communal shower areas, locker rooms, and pool decks
- Trim nails straight across and file sharp edges to reduce the risk of nail trauma
- Choose nail salons that sterilize tools properly between clients
- Treat athlete’s foot promptly to prevent the infection from spreading to the nails
- If you have diabetes, inspect your feet and nails daily and see your podiatrist regularly

Frequently Asked Questions
Can a fungal nail infection go away on its own?
In the vast majority of cases, no. Fungal nail infections are caused by organisms that are well adapted to surviving within the nail structure. Without appropriate antifungal treatment, the infection typically persists and spreads. Early professional treatment gives you the best chance of a full recovery.
Is nail fungus contagious?
Yes. Fungal organisms can spread from person to person through direct contact or shared surfaces such as shower floors, towels, or nail tools. They can also spread from one nail to another on the same foot. Practicing good foot hygiene and avoiding shared nail care tools reduces the risk of transmission.
Can I paint my nails over a fungal infection?
It is generally not recommended. Nail polish traps moisture and prevents any topical treatment from reaching the nail. It can also make it difficult to monitor the progress of the infection. If you use nail polish, ask your FitFeet podiatrist for guidance on managing this during treatment.
Is laser treatment for nail fungus effective?
Laser therapy for onychomycosis has shown promising results in clinical studies and is a good option for patients who prefer to avoid medications or who have not responded to other treatments. Multiple sessions are typically needed. Your FitFeet podiatrist can discuss whether laser therapy is appropriate for your specific situation.
How do I know if my nail infection has cleared?
Clearing of a fungal nail infection is confirmed by the growth of new, healthy nail from the base outward. Because this process takes months, your podiatrist may also order a follow-up nail culture to confirm the fungal organisms are no longer present. Do not stop treatment based on visual improvement alone without consulting your podiatrist.
Are people with diabetes at higher risk for nail fungus?
Yes. People with diabetes have an elevated risk of fungal nail infections due to reduced circulation and a compromised immune response. Fungal infections in diabetic patients can also lead to more serious complications if left untreated. Diabetic patients should have their feet and nails examined regularly by a podiatrist at FitFeet.
