A nail fungal infection or onychomycosis is a common condition that affects both the fingernails and toenails. This can make your nails discolored, brittle, crumbly, and misshapen. Sometimes when the nail fungus has become severe, this may cause the nail to separate from the nail bed, causing pain and discomfort and at times even a foul odor. This condition affects just about everyone, but it is more prevalent among older men.
15What are its common causes?
Fungus thrive without sunlight. In fact, they grow more in dark, warm, and moist environments. The most common cause of this condition is a group of fungi known as dermatophytes. Yeasts and molds may also cause nail fungal infections.
