Contagious Toenail Fungus

Monday, 16 December 2019 00:00

Toenail fungus is typically caused by a nail infection. The medical term for this type of fungus is known as onychomycosis. Common symptoms can include thicker nails, nail discoloration, and in severe cases, the nail may split. Patients may notice pain when the affected nail is pressing against the inside of the shoe. The fungus that causes this type of infection thrives in warm and moist environments that can include shower and locker room floors, and public pools. It may help to wear appropriate shoes while in these areas, and this may be beneficial in preventing this infection. People who are diabetic, obese, or have a family history of toenail fungus may be more susceptible to developing toenail fungus. If you notice symptoms of this condition, it is suggested that you consult with a podiatrist who can offer proper treatment options. 

If left untreated, toenail fungus may spread to other toenails, skin, or even fingernails. If you suspect you have toenail fungus it is important to seek treatment right away. For more information about treatment, contact Dr. Steven Sheridan of Ankle & Foot Specialty Clinics. Our doctor can provide the care you need to keep you pain-free and on your feet.


  • Warped or oddly shaped nails
  • Yellowish nails
  • Loose/separated nail
  • Buildup of bits and pieces of nail fragments under the nail
  • Brittle, broken, thickened nail


If self-care strategies and over-the-counter medications does not help your fungus, your podiatrist may give you a prescription drug instead. Even if you find relief from your toenail fungus symptoms, you may experience a repeat infection in the future.


In order to prevent getting toenail fungus in the future, you should always make sure to wash your feet with soap and water. After washing, it is important to dry your feet thoroughly especially in between the toes. When trimming your toenails, be sure to trim straight across instead of in a rounded shape. It is crucial not to cover up discolored nails with nail polish because that will prevent your nail from being able to “breathe”.

In some cases, surgical procedure may be needed to remove the toenail fungus. Consult with your podiatrist about the best treatment options for your case of toenail fungus.
