Ingrown nail

Medical condition

An ingrown nail, also known as onychocryptosis (from Ancient Greek: ὄνυξ, romanized: ónux, lit. 'nail'; and κρυπτός, kruptós, 'hidden') is a common form of nail disease. It is an often painful condition in which the nail grows so that it cuts into one or both sides of the paronychium or nail bed. While any nail can become ingrown, wearing shoes causes the toenails to grow in more often.
