An ingrown toenail, also known as onychocryptosis or unguis incarnatus, is a painful condition of the toe. It occurs when a sharp corner of the toenail digs into the skin at the end of or side of the toe. Pain and inflammation at the spot where the nail curls into the skin occurs first. Later, the inflamed area can begin to grow extra tissue or drain yellowish fluid.

• If left untreated, an ingrown toenail can progress to an infection or even an abscess that requires surgical treatment. Osteomyelitis is a rare complication of an infected toe, in which the bone itself becomes infected.
• Ingrown toenails are common in adults and adolescents but uncommon in children and infants. They are more common in men than in women. Young adults in their 20s or 30s are most at risk.
• Any toenail can become ingrown, but the condition is usually found in the big toe.
