Ingrown Toe Nail
Onychocryptosis (also known as an "Ingrown nail," or "Unguis incarnatus") 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 nail bed. While ingrown nails can occur in both the nails of the hand and feet, they occur most commonly with the toenails.
An "ingrown" toenail often is not really an "ingrown" toenail at all. The appearance of being ingrown may actually a result of inflammation of the flesh around the nail. The nail becomes embedded and soft under the flesh that has inflamed around it.
