Alternative Names

An ingrown toenail can result from curved toenails, poorly fitting shoes, toenails that are trimmed improperly, or a toe injury. The skin around the toenail may become red and infected. The great toe is usually affected, but any toenail can become ingrown.
The condition may become serious in people with diabetes.
