Fungal Nail Treatment in Glendale, AZ
Fungal nail infections (onychomycosis) are among the most common nail disorders treated by podiatrists — and among the most frequently undertreated. What often starts as a small discoloration can progress over months into thickened, brittle, and crumbling nails that are difficult to manage at home. At Sole Foot & Ankle Specialists, our board-certified podiatrists offer accurate diagnosis and advanced treatment options to restore your nail health and prevent reinfection.
What Is a Fungal Nail Infection?
Onychomycosis is a chronic fungal infection of the toenails (or less commonly, fingernails) caused most often by dermatophyte fungi — the same organisms responsible for athlete’s foot. The fungus invades the nail plate and nail bed, where it feeds on keratin and thrives in the warm, dark, moist environment inside a shoe. Without treatment, the infection typically spreads slowly across the nail and may eventually affect multiple nails. There are several types of onychomycosis:
- Distal subungual onychomycosis (DSO): The most common type, beginning at the tip of the nail and progressing toward the nail base
- Proximal subungual onychomycosis (PSO): Begins near the cuticle; more common in immunocompromised patients including those with HIV
- White superficial onychomycosis (WSO): Affects the surface of the nail, causing white powdery patches
- Candidal onychomycosis: Caused by Candida yeast, often associated with chronic exposure to water or compromised immunity
Signs and Symptoms of Fungal Nails
Fungal nail infections are progressive and worsen without treatment. Warning signs include:
- Yellow, white, or brown discoloration affecting part or all of the nail
- Thickened or misshapen nails that are difficult to trim
- Brittle, crumbly, or ragged nail edges
- Nails that separate or lift away from the nail bed (onycholysis)
- Debris accumulation under the nail
- Foul odor from the affected nail
- Pain or discomfort when wearing shoes, especially in advanced cases
If you also notice itching, scaling, or peeling skin between your toes alongside nail changes, you may have a concurrent athlete’s foot infection — both conditions often occur together and should be treated simultaneously to prevent reinfection.
Risk Factors for Fungal Nail Infections
Several factors increase the likelihood of developing onychomycosis:
- Walking barefoot in public locker rooms, gym showers, or pool decks
- Wearing tight, closed-toe, or non-breathable footwear
- Nail trauma or injury that disrupts the nail plate
- Reduced immune function from diabetes, chronic illness, or medications
- Poor circulation to the feet, including peripheral arterial disease
- Age — older adults have slower nail growth and more years of cumulative exposure
- History of athlete’s foot
- Having a family member with a fungal nail infection
Fungal Nail Treatment Options in Glendale, AZ
Fungal nail infections are notoriously difficult to treat without professional care — over-the-counter products have limited penetration through the nail plate and typically do not eliminate the infection. At Sole Foot & Ankle Specialists, we offer a range of clinically proven treatment approaches:
- Prescription topical antifungals: Specialty nail lacquers or solutions (such as efinaconazole or tavaborole) that penetrate the nail plate more effectively than OTC products
- Oral antifungal medications: Systemic medications such as terbinafine or itraconazole are often the most effective treatment for moderate to severe onychomycosis, with close monitoring for side effects
- Laser nail therapy: A non-invasive treatment that uses targeted laser energy to destroy fungal organisms in the nail bed without harming surrounding tissue
- Nail debridement: Professional trimming and filing of the infected nail to reduce bulk, improve topical penetration, and relieve pressure
- Nail avulsion: In severe cases, partial or complete removal of the nail may be recommended to allow direct treatment of the nail bed
Treatment for fungal nails is a long-term commitment — nails grow slowly, and full resolution typically takes 6 to 12 months after starting treatment. Our team monitors your progress and adjusts the treatment plan as needed to optimize outcomes.
Frequently Asked Questions About Fungal Nail Infections
How do I know if my nail is fungal or just discolored from trauma?
Nail discoloration can be caused by fungal infection, trauma, psoriasis, or other conditions. Fungal nails typically show progressive thickening, brittleness, and a yellowish-brown discoloration that begins at the tip or edges. Traumatic nail changes often follow an injury and may include dark bruising under the nail. The only way to confirm a fungal infection with certainty is a laboratory nail sample culture or PCR test performed by a podiatrist. Treating a non-fungal nail with antifungals will be ineffective.
Why are fungal nail infections so hard to cure?
The nail plate acts as a physical barrier that limits penetration of topical treatments to the nail bed where the fungus lives. Additionally, nails grow slowly — replacing a toenail fully takes 12 to 18 months — so even effective treatment takes a long time to show visible results. Incomplete treatment, reinfection from contaminated shoes or environments, and immune factors all contribute to treatment challenges. Consistent, professionally guided treatment is essential.
Can fungal nails spread to other toes or family members?
Yes. Onychomycosis is contagious. The fungus can spread from one nail to others, from infected nails to skin (causing athlete’s foot), and between people who share surfaces, footwear, or towels. Treating all infected nails simultaneously, disinfecting shoes, and practicing good foot hygiene are essential steps to prevent spread during treatment.
Are oral antifungal medications safe?
Oral antifungals like terbinafine are safe for most patients but require monitoring for liver effects, especially in patients with underlying liver conditions or those taking certain other medications. Our podiatrists review your medical history thoroughly before prescribing oral antifungals and can order baseline blood work when indicated. The risk-benefit profile is favorable for most patients with moderate to severe infections.
Does laser treatment for nail fungus work?
Laser therapy is an effective option for patients who cannot tolerate oral medications or prefer a non-systemic approach. It uses precise wavelengths of light to heat and destroy fungal organisms within the nail bed without causing harm to surrounding skin or tissue. Multiple sessions are typically required, and results develop gradually as the nail grows out. Our podiatrists can help you determine if laser therapy is the right option for your specific case.
How can I prevent a fungal nail infection from coming back after treatment?
Preventing reinfection requires addressing the environmental and hygiene factors that allowed the original infection to occur: always wear sandals in public wet areas, replace or disinfect old shoes (spraying with antifungal powder or UV shoe sanitizers), change socks daily, keep nails trimmed and clean, and treat any concurrent athlete’s foot promptly. For high-risk patients, our podiatrists may recommend periodic preventive treatments.
Can diabetic patients be treated for fungal nails?
Yes, and treatment is especially important for diabetic patients. Thickened, infected nails can cause pressure sores and provide an entry point for bacterial infection, which can rapidly escalate in patients with impaired immunity or circulation. Our podiatrists specialize in diabetic foot care and tailor nail treatment to each patient’s overall health status and risk profile.
