ingrown nail

aberrant growth of a toenail, with one or both lateral margins pushing deeply into adjacent soft tissue, causing pain, inflammation, and possible infection. The condition occurs most frequently in the great toe, and is often caused by pressure from tight-fitting shoes. Another common cause is improper cutting of the toenails, which should be cut straight across or with a curved toenail scissors so that the sides are a little longer than the middle.
