Which of the following is a common symptom of nail fungus?

Separation of the nail from its bed is a common symptom of nail fungus, also known as onychomycosis. This condition occurs when a fungal infection penetrates the nail and the skin underneath. The infection typically leads to the nail lifting away from the nail bed, creating a gap where debris and moisture can accumulate, exacerbating the problem. This symptom can also cause discomfort and make the nail more susceptible to further infection and damage.

Other symptoms, such as discoloration or pain during nail application, can be associated with various nail conditions or injuries, but the specific symptom of nail separation is more directly indicative of a fungal infection. Understanding these symptoms is crucial for nail technicians, as it allows for appropriate identification and recommendation for clients who might be suffering from fungal infections. Proper hygiene, treatment, and avoidance of contaminated environments are essential in managing nail fungus.
