Ingrown toenails usually occur when the corner or side of a toenail grows into the soft flesh, causing pain, inflammation, swelling, and sometimes infection. This condition usually affects the big toe and is often caused by cutting toenails too short or tapering around the corners. It is important to see a dermatologist if you have symptomes or suspect an infection.

Treatment options include wearing comfortable shoes, and gently lifting the nail out of the skin. In severe cases, surgery may be necessary.
