What is typically a sign of onychomycosis?

Discoloration of the nail
Growth of hangnails
Severe pain in the nail
Thickening of the cuticle

The correct answer is: Discoloration of the nail

Onychomycosis is a fungal infection of the nails that manifests in several characteristic ways, with discoloration being one of the most notable signs. When onychomycosis is present, the affected nails often appear discolored, taking on shades of yellow, white, or even green, depending on the type of fungus causing the infection. This discoloration is due to the accumulation of debris under the nail and changes in the nail bed's health, which serves as a clear indicator of underlying fungal activity. Other symptoms, such as thickening or crumbling of the nail, may also occur, but discoloration is among the most recognizable indicators, often prompting individuals to seek treatment. Being alert to these signs can help in early diagnosis and management of the infection.
