Health Tip: Signs of Nail Fungus

(HealthDay News) -- Fungi can creep underneath nails on the toes and fingers, causing an infection. While this problem usually can be treated with a prescription medication, keeping nails clean and dry can help prevent it in the first place.

The U.S. National Library of Medicine lists these warning signs of a fungal nail infection:

• A nail that is brittle and crumbles.
• A change in the way the nail is shaped.
• A thick nail.
• A change in the color of the nail.
• A nail that is dull, or is separating from the skin.
• A nail that appears to have particles beneath it.
