<span>In an ingrown nail, the nail sliver penetrates the skin,
resulting in inflammation that may hinder ambulation and interfere with
activities of daily living. After the nail sliver is removed by a podiatrist,
treatment involves soaking the foot in warm water and applying antibiotic
ointment. Application of an ice pack is suitable for plantar fasciitis rather
than an ingrown toenail. Treatment of secondary infection is advised in
hypertrophic ungual labium, which results from an untreated ingrown nail. The
application of padding and lanolin creams is recommended for calluses.</span></span>
