How to Know If You Have Toenail Fungus (And What to Do Next)

Toenail fungus is a common yet often overlooked condition that can affect anyone. It's slow to develop and easy to ignore—until it starts changing the appearance of your nails. If you're wondering whether that strange discoloration or thickening on your nail is actually a fungal infection, you're not alone. Here's how to identify toenail fungus early and what you should do if you spot the signs.

What Is Toenail Fungus?

Toenail fungus, or onychomycosis, is a fungal infection that invades the nail bed and surrounding skin. It thrives in warm, damp environments and spreads slowly, often starting in one nail and progressing over time.

Common Signs of Toenail Fungus

Not sure if you have it? Here are the most common symptoms to look out for:

  • Yellow, brown, or white discoloration on the nail

  • Thickened nails that are difficult to trim

  • Brittle, crumbly, or ragged edges

  • Distorted nail shape

  • A foul odor coming from the nail

  • Separation of the nail from the nail bed

  • Mild pain or discomfort, especially when wearing shoes

⚠️ Pro Tip: If more than one nail is affected or the symptoms are spreading, it's important to act quickly.

Causes and Risk Factors

Toenail fungus is caused by dermatophytes, yeasts, or molds. You’re more likely to get it if you:

  • Walk barefoot in public showers, gyms, or pools

  • Wear sweaty socks or tight shoes

  • Have athlete’s foot or other skin infections

  • Have diabetes, poor circulation, or a weakened immune system

  • Don’t practice good foot hygiene

What to Do Next: Step-by-Step

1. Confirm It’s Fungus

If you're unsure, consult a healthcare provider or dermatologist. In some cases, they might scrape the nail or send a sample for testing to confirm the infection.

2. Start Treatment Early

The earlier you begin treatment, the easier it is to stop the fungus from spreading. You have a few options:

  • Topical treatments: Over-the-counter or natural remedies like tea tree oil, oregano oil, or antifungal creams.

  • Prescription medications: Oral antifungals like terbinafine (Lamisil) or itraconazole.

  • Laser treatments: A newer option that targets fungus without damaging the nail.

3. Practice Consistent Nail Care

  • Trim and file the nails regularly.

  • Keep feet clean and dry.

  • Disinfect nail tools and footwear.

4. Prevent It From Coming Back

After treating the infection, prevention is key. Use antifungal powders, avoid going barefoot in public areas, and wear breathable footwear.

When to See a Doctor

See a healthcare provider if:

  • The nail is severely discolored or thickened

  • The infection is spreading to other nails

  • You have diabetes or a compromised immune system

  • Home treatments aren’t working after a few weeks

Final Thoughts

Recognizing the early signs of toenail fungus is the first step to healthy nails. With fast action and the right treatment, you can stop the infection in its tracks and prevent long-term damage. Whether you choose natural remedies or medical options, consistency and proper foot care make all the difference.
