Diseases & Conditions
Easy-to-understand answers about diseases and conditions
Nail fungus, medically known as onychomycosis (on-ih-koh-my-KOH-sis), is a prevalent nail infection. It initiates as a white or yellow-brown spot beneath the tip of your toenail or fingernail. As the fungal infection progresses, the affected nail might darken, thicken, and become brittle at the edges. This condition can impact multiple nails simultaneously. In cases where the infection is mild and doesn’t cause discomfort, treatment may not be necessary. For those experiencing painful nail fungus leading to thickened nails, a combination of self-care measures and medications can offer relief. However, it’s important to note that even with successful treatment, nail fungus recurrence is common. Nail fungus can also manifest as athlete’s foot (tinea pedis) when it affects the skin between your toes and the soles of your feet. If you encounter nail fungus, addressing the condition early can help prevent its progression and recurrence.
