What is a condition where the nail grows into the surrounding skin?

The condition in which a nail grows into the surrounding skin is known as onychocryptosis. This occurs commonly on the toenails, particularly the big toe, and leads to pain, inflammation, and sometimes infection as the nail edges penetrate the skin. Proper nail trimming habits and wearing appropriate footwear can help prevent this condition.

Onychomadesis refers to the separation of the nail from the nail bed and is usually temporary, often due to illness or trauma. Onycholysis is the lifting of the nail plate from the nail bed, which can also result from various factors, including injury or infection, but does not involve the nail growing into the skin. Chronic paronychia is a condition where the skin surrounding the nail becomes inflamed, often due to repeated exposure to moisture or irritants, but it does not specifically describe the situation of the nail growing into the surrounding skin.
