Ingrown toenails are a common condition in which the corner or side of a toenail grows into the soft flesh. The result is pain, redness, swelling and, sometimes, an infection. Ingrown toenails usually affect your big toe.
Often you can take care of ingrown toenails on your own. If the pain is severe or spreading, your doctor can take steps to relieve your discomfort and help you avoid complications of ingrown toenails.
If you have diabetes or another condition that causes poor blood flow to your feet, you're at greater risk of complications of ingrown toenails.
