Healthy nails are more than a cosmetic feature; they can also reflect your overall health. A fungal nail infection can affect either your fingernails or toenails, making them thick, discolored, brittle, and difficult to manage. While toenail fungus is more common, fingernails, toenail fungus can also become infected, especially after frequent exposure to moisture or injury.

The good news is that early treatment and proper nail care can help stop the infection from getting worse. This guide explains everything you need to know in simple words.

What Is Hand Toenail Fungus?

Hand toenail fungus, also called fungal nail infection or onychomycosis, is an infection caused by fungi that grow under or around the nail.

The infection usually begins as a small white or yellow spot under the nail. If left untreated, it can spread deeper into the nail, causing discoloration, thickening, and crumbling.

Toenails are affected more often because they spend long hours inside warm, sweaty shoes. Fingernails may become infected after frequent contact with water, detergents, or shared nail tools.

Common Symptoms

You may have a fungal nail infection if you notice:

• Yellow, white, or brown nail discoloration
• Thickened nails
• Brittle or crumbly nails
• Rough or uneven nail surface
• Nail lifting away from the nail bed
• Bad smell from the affected nail
• Pain while walking or using your hands in severe cases

Symptoms often develop slowly, so many people ignore them during the early stages.
