What is a common symptom of nail fungus?

A common symptom of nail fungus is the separation of nails from the nail bed. This occurs as the fungus infects the nail, leading to changes in the nail's structure and health. The infection disrupts the bond between the nail and the nail bed, causing the nail to lift and separate, which can be painful and unsightly.

Other symptoms of nail fungus may include discoloration, thickening, or crumbling of the nail. However, the primary and indicative symptom of the progression of the infection is this separation from the nail bed. Understanding this symptom is crucial for effectively diagnosing and treating nail fungus, as timely intervention can help prevent further damage to the nail and surrounding skin.
