Ingrown Toe Nail

Onychocryptosis is an often painful condition in which the nail grows so that it cuts into one or both sides of the nail bed. This condition has been found only in shoe-wearing cultures and does not occur in habitually barefoot people since it requires downward pressure on the nail by a shoe.

Ingrown nails can be avoided by cutting nails straight across; nails should not be cut along a curve, nor should they be cut too short.
