Doctor's Notes on Ingrown Toenails (Onychocryptosis, Unguis Incarnatus)

Ingrown toenails, medically known as onychocryptosis, are caused by a toenail growing into the surrounding nail fold. Some conditions that may predispose to the development of ingrown toenails include injuries, poor foot hygiene, deformities of the toes or feet, and improper footwear. Ingrown toenails are most commonly seen in the big toe and are a relatively common problem.

Associated signs and symptoms include redness, pain, and swelling of the affected toe. In many cases, an ingrown toenail may become infected. In the case of an infection, drainage of yellowish pus may occur from the site. Other symptoms associated with ingrown toenails can include limping or gait disturbances if the pain interferes with walking and the development of scar tissue at the site.
