Foot Conditions A-Z
Many people have experienced the pain of ingrown toenail. It occurs when the corner or side of a toenail grows into the soft flesh of the toe, most often the big toe. Ingrown toenails can cause pain, swelling, redness and sometimes infection. According to the 2012 National Foot Health Assessment conducted by the NPD Group for the Institute for Preventive Foot Health, 18 percent of U.S. adults age 21 and older (40 million people) have experienced ingrown toenail.
