Short answer: Toenail fungus can cause nails to appear thicker and discolored, often with loose material underneath. If it’s unclear, a painless biopsy can confirm infection. It’s important to diagnose a fungal infection correctly before starting treatment.
What to Look for in Toenail Fungus
Fungal infection of the toenail, also known as onychomycosis, often changes the nail’s appearance. Common signs include thickening of the nail, a yellow, brown, or even white discoloration, and crumbly or ragged edges. Additionally, you might notice a buildup of white or yellowish material underneath the nail, making it lift from the nail bed. These changes may not affect the entire nail but might only impact part of it. The nail may become brittle, and the surface could turn uneven and rough. Sometimes the nail may emit a foul odor.
How to Confirm Toenail Fungus
If your toenail shows signs of infection, but you’re unsure if it’s fungus, a biopsy can confirm the diagnosis. Our clinic in Houston can perform a simple, painless biopsy of the nail. This involves taking a small sample of the nail and sending it to a lab for analysis, with results typically available within a week. This step is crucial when conditions like trauma or psoriasis cause nail damage, as they can mimic fungal infection by also causing nail thickening or discoloration. Confirming fungus allows us to recommend the most effective treatments tailored to your specific condition.
Home Care for Potential Toenail Fungus
While professional diagnosis is important, you can start by keeping your feet clean and dry, as moisture creates an ideal environment for fungus to grow. Trim your toenails straight across to prevent them from becoming ingrown. If you suspect a fungal infection, avoid using nail polish and cover the nail in breathable footwear. Over-the-counter topical treatments, such as antifungal creams or ointments, might help, but they are generally less effective than professional treatments. Follow all package instructions and give these treatments ample time to work, usually a few weeks to months. However, home care is not a substitute for professional evaluation, especially if symptoms persist or worsen.
Treatment Options for Toenail Fungus
Once a fungal infection is confirmed, a range of treatment options can be explored. Topical antifungal medications are common for mild cases but can take a long time to show results. Oral medications are often more effective for severe infections, as they reach the nail through the bloodstream. At DeNiel Foot & Ankle Center, we offer PinPointe laser treatment, a non-invasive option that uses laser technology to target the fungus without harming surrounding tissue. While effective, treating toenail fungus requires patience, as full nail regrowth is needed to see complete results, which can take several months.
When to See a Podiatrist
Nails are thickening or discoloring without an obvious cause.
There is persistent pain, discomfort, or a change in the appearance of the toenails.
The nail has a foul odor or is separating from the nail bed.
You have diabetes, poor circulation, or signs of infection, such as redness, swelling, or warmth.
Home treatments are ineffective, or the condition seems to be spreading.
Recognizing toenail fungus early can significantly improve treatment outcomes. If you’re in the Houston or Cypress area and suspect you have toenail fungus, visit DeNiel Foot & Ankle Center for an expert evaluation and an appropriate treatment plan tailored to your needs.
