An ingrown toenail occurs when the nail grows into the skin, causing pain and sometimes an infection.

To avoid the problem, the American Podiatric Medical Association suggests:

• Trimming toenails straight across.
• Avoiding tight shoes that squeeze the toes.
• Protecting feet from injury.
• Using nail clippers to trim the nails, and using a nail file to gently smooth sharp edges. Never rip a nail with your fingers.
• Keeping nails trimmed to the tips of the toes.
