What is a common symptom of onychomycosis?

Onychomycosis is a fungal infection that affects the nails, leading to various symptoms. The thickening of the nail is a primary manifestation of this condition. As the fungal infection progresses, the nail may appear distorted and the structure of the nail plate thickens due to the accumulation of debris beneath it. This thickening can also make the nail more brittle and prone to breaking.

While other symptoms may present in severe cases, such as the potential for nail loss or changes in the nail plate's positioning, the thickening itself is the most common and recognizable early sign that prompts individuals to seek further evaluation or treatment. Recognizing this symptom is crucial in addressing the condition promptly and effectively.
