Fungal infections of the skin and nails are some of the most common conditions seen in podiatry offices. While they may start as a cosmetic nuisance, these infections can become painful, persistent, and even lead to more serious complications if untreated—especially for individuals with diabetes or circulation issues. At Henry Tseng, DPM, we provide expert diagnosis and treatment for fungal infections to restore the health and appearance of your feet.
What Is Skin and Nail Fungus?
Skin fungus, often called athlete’s foot (tinea pedis), is a contagious fungal infection that affects the skin between the toes, on the soles, or sides of the feet.
Nail fungus, medically known as onychomycosis, is an infection that occurs when fungi invade the nail bed, leading to discoloration, thickening, and brittleness of the toenail.
Both infections are caused by similar organisms—typically dermatophytes, yeast, or molds—that thrive in warm, moist environments like shoes, socks, locker rooms, and public showers.
Common Signs and Symptoms
Skin Fungus (Athlete’s Foot):
- Itching, burning, or stinging sensations between the toes
- Peeling or cracking skin
- Red, scaly rash
- Unpleasant odor
Nail Fungus:
- Yellow, brown, or white discoloration of the nail
- Thickened, brittle, or crumbly nail surface
- Nail separation from the nail bed (onycholysis)
- Foul odor or discomfort when walking
Why It Happens
Fungal infections develop when microorganisms find an entry point through tiny cuts or separations in the nail or skin. Factors that increase the risk include:
- Walking barefoot in public showers or pools
- Wearing tight or non-breathable shoes
- Excessive sweating (hyperhidrosis)
- Weakened immune system or diabetes
- Nail trauma or previous infections
Treatment Options at Henry Tseng, DPM
Dr. Tseng offers a range of modern, effective treatments tailored to your condition and lifestyle:
- Topical Antifungal Medications:
Creams, sprays, or medicated nail lacquers are used to target mild infections on the surface of the skin or nail. - Oral Antifungal Therapy:

A state-of-the-art, non-invasive option that uses focused light energy to kill fungal organisms beneath the nail surface without damaging healthy tissue. - Debridement and Nail Care:
Dr. Tseng can safely trim, thin, or remove affected nail portions to relieve discomfort and improve medication effectiveness. - Preventive Foot Care:
Education and maintenance strategies are key to keeping infections from recurring—Dr. Tseng helps patients establish effective at-home hygiene habits.
How to Prevent Recurrence
- Wash and dry your feet thoroughly, especially between the toes.
- Use antifungal powders or sprays in shoes and socks.
- Avoid walking barefoot in public areas.
- Change socks daily and wear moisture-wicking materials.
- Choose breathable footwear and alternate pairs regularly.
- Disinfect nail clippers and avoid sharing pedicure tools.
Q&A: Skin and Nail Fungus
Q: Is nail fungus contagious?
A: Yes, fungal infections can spread through direct contact or by sharing contaminated items like towels, shoes, or nail clippers.
Q: Can I treat nail fungus at home with over-the-counter products?
A: Mild infections may respond to OTC creams or antifungal polishes, but deeper or long-standing infections typically require professional treatment for lasting results.
Q: How long does treatment take?
A: Nail fungus can be stubborn. Depending on severity, complete clearance may take several months since new, healthy nails need time to grow out.
Q: Does laser treatment hurt?
A: Laser therapy is generally well tolerated. Patients might feel warmth or mild tingling during the session, but discomfort is minimal and no downtime is needed.
Q: Can fungus come back after treatment?
A: Yes, recurrence is possible if proper foot hygiene isn’t maintained. Regular follow-up and preventive measures can significantly reduce this risk.
Q: When should I see a podiatrist?
A: If you notice nail discoloration, thickening, pain, or persistent skin irritation on your feet, it’s best to schedule an evaluation before the infection worsens.
