Ingrown Toenail
Causes of Ingrown Toenails
Cutting the toenails too short and/or not cutting them straight across is the most common cause of ingrown toenails. Another common cause is shoes that are too short or that fit too tightly and compress the toes together. They can also be due to trauma or injury to the toe or toenail. People whose toes are unusually curved are prone to having ingrown toenails.
