Toenail Fungus Specialist

If you have yellow, thick, crumbling toenails, it is very likely that you suffer from a fungal infection of the toenail. While many patients don’t seek treatment because they believe these infections are too hard to treat, laser treatment is pain-free and highly effective in fighting fungal infections in the toenails. Dr. Richard P. Jacoby at Extremity Health Centers in Scottsdale, Arizona, provides multifaceted treatment for this condition.

Toenail Fungus Q & A

What is toenail fungus?

Toenail fungus, also called onychomycosis or tinea unguium, is an infection that develops under the surface of the toenail. If treatment isn’t sought when symptoms first present, the fungal infection can extend deeper into the nail, causing the nail thicken, become weak, and eventually fall off.

What types of fungal nail infections are there?

Although many patients don’t realize it, there are several types of fungus that contribute to fungal infection in the toenails, each requiring unique treatment. These include:

  • Distal subungual onychomycosis (DSO): Also called Athlete’s foot, DSO is the most common fungal infection in the toenails, resulting in weak and discolored nails.
  • White superficial onychomycosis (WSO): WSO is much less common and generally produces patchy white areas on the entirety of the nail.
  • Candida onychomycosis: This fungus is chronic and generally the result of trauma to the toenail and results in a dome-shaped, enlarged toenail.
  • Proximal subungual onychomycosis (PSO): Like WSO, this infection presents as white or yellow spots, but they are usually confined to the base of the toenail.

What are the signs and symptoms of toenail fungus?

Because there are several different kinds of toenail fungus, and each can worsen if left untreated and put you at risk of losing a toenail, it’s important to seek diagnosis and treatment from a podiatrist as soon as you notice symptoms. The most common signs and symptoms include:

  • Thick, flaky toenails
  • Scaling underneath the nail
  • Yellow or white spots or streaks on the nail
  • Foul odor
  • Crumbling that begins at the tip
  • Nail loss

How are fungal nail infections treated?

Some patients aren’t bothered by minor fungal infections and may not seek treatment, but it’s important to note that these infections are often contagious and can spread to others. Additionally, contagious fungal infections can spread to your other toenails.

While fungal nail infections are traditionally hard to treat, laser technology has provided new success for patients. Laser treatment is a highly effective non-invasive treatment for mild to severe fungal infections of the nails. Other treatments include oral or topical medications. In some severe cases, nail avulsion surgery may be recommended.
