Toenail Fungus Symptoms

Toenail fungus affects both adults and children, but it's more common in adults. According to the U.S. National Library of Medicine, toenail fungus often targets individuals who frequent gyms and other public areas where there is warm, moist air. Toenail fungus symptoms vary depending on how early the infection is diagnosed and what type of fungal infection is involved.

Toenail Changes

• Any sudden changes to toenails including discoloration, shape changes and brittleness could indicate a fungal infection.

Thickening Brittle Nails

• Thickening and brittle toenails are common indicators of toenail fungus. The toenails will often crumble or break easily and may have lost their shine.

Toenail Lifting

• Infected toenails may lift from the nail bed. If toenails are separating from the toe and/or there is pain or swelling, individuals should consult a doctor to prevent secondary fungal or bacterial infections.

Discoloration

• Toenail discoloration can happen during any stage of a toenail fungus infection. An early sign of fungal infection is yellowing of the toenail. Darker discoloration usually occurs as the infection progresses.

Toenail Injuries

• Injuries to toenails should be checked for discoloration after bruising subsides. Fungus is more apt to occur when a toenail has been damaged or pulls away from the nail bed.
