Nail Fungus

A nail fungus (onychomycosis) is a common disorder that causes nails, most often toenails, to become brittle, thickened, and discolored. Many individuals first notice subtle changes in nail color or texture, which may gradually worsen if the infection is not addressed.

Nail fungus is similar to athlete’s foot, but it affects a different area. Instead of involving the skin on the soles or between the toes, the infection spreads into the nail plate and the underlying nail bed. Once the infection establishes itself within the nail structure, it can be more challenging to manage without appropriate medical care.

Fungi are microscopic organisms that are only visible under a microscope. Multiple types of fungi can lead to nail infections. In some cases, these organisms live on the skin without causing symptoms. When they multiply in a concentrated area, an infection can develop, which leads to visible nail changes and structural damage.

Fungal nail infections are extremely common and can affect both toenails and fingernails, though toenails are more frequently involved.

Fungal nail symptoms vary depending on the type of infection. In most cases, the condition begins subtly and progresses over time. 

What Is the First Sign of Toenail Fungus?

The earliest sign is often a small white or yellow spot beneath the nail. At this stage, there is usually no pain. As the infection spreads, discoloration can extend deeper into the nail and involve a larger area.

Over time, the affected nail may turn white, yellow, green, or black. This color change is one of the most recognizable signs of fungal nails.

How Do Fungal Nails Change Over Time?

As the infection progresses, structural changes become more noticeable:

• The nail may become difficult to trim 
• Curving upward or downward
• Separation from the nail bed
• Brittleness and crumbling with touch
• Misshapen or distorted appearance
• Unpleasant odor

These changes can affect both appearance and function, especially with untreated toenail fungus.

Does Toenail Fungus Cause Pain?

Early stages of fungal nails are often painless, which makes them easy to ignore. Without treatment, pressure on the affected area can become uncomfortable. In more advanced cases, walking may become difficult if the infection significantly damages the nail.

Nail fungus can be difficult to eliminate without medical care. If signs of infection are present, a qualified podiatrist should be consulted. 

What Are Oral Antifungal Medications?

Oral antifungal medications are prescription pills designed to kill fungus throughout the body. This approach is often the most effective treatment for a nail infection.

The length of treatment varies based on where the infection is located.

• Approximately 2 months for fingernail infections
• Approximately 3 months for toenail infections

Oral therapy targets the infection from within and is commonly recommended for more established cases of toenail fungus.

What Are Topical Antifungal Treatments?

Topical antifungals are medications applied directly to the nail surface. They are brushed or rubbed onto the affected nail.

These medications can be helpful in treating mild cases of infection. However, because they do not penetrate deeply into the nail structure, they are less effective for more advanced cases. In some situations, a topical medication may be used in combination with an oral antifungal for improved results.

Is Laser Therapy Available for Nail Fungus?

At Central Florida Foot and Ankle Center, laser therapy is offered as part of advanced nail fungus treatment options. This method uses focused light energy to penetrate the infected nail and generate heat that targets and destroys the fungus.

Laser treatment is non-invasive and generally painless. Most patients require only one treatment session. For individuals experiencing persistent, severe, or recurring toenail fungus, laser therapy may be an effective treatment option.
