What is a common symptom of a fungal infection in nails?

A common symptom of a fungal infection in nails is the discoloration and thickening of the nail. Fungal infections can cause nails to appear yellow, brown, or even white, leading to a noticeable change in their typical color. This discoloration often occurs due to the accumulation of fungal elements beneath the nail plate.

Additionally, as the infection progresses, the nail can become thickened and distorted, losing its smooth texture. This thickening can make the nail more difficult to trim and can also lead to other complications if left untreated.

While other symptoms can accompany fungal infections, such as separation from the nail bed and sometimes mild discomfort, the hallmark indicators are specifically the changes in color and thickness, which are direct results of the infection affecting the structure of the nail itself.
