Ingrown toenails are a common condition in which the corner or side of a toenail grows into the soft flesh. This can happen when the toenail is cut too short or curved. It can also be caused by wearing shoes that are too tight. Ingrown toenails can be painful and may cause swelling, redness, and infection.
People who have diabetes or poor circulation are at higher risk for developing ingrown toenails.
In some cases, ingrown toenails will require corrective surgery to remove the part of the nail that has grown into the skin. Surgical treatment for ingrown nails is more effective at preventing the nail from regrowing inwards compared to non-surgical treatments.
