Ingrown nail
Ingrown nails, the most common nail impairment, are nails whose corners or sides
dig painfully into the soft tissue of nail grooves, often leading to irritation,
redness, and swelling. Usually, toenails grow straight out. Sometimes,
however, one or both corners or sides curve and grow into the flesh. The big toe is
the most common location for this condition, but other toes can also become
affected.
Ingrown toenails may be caused by the following:
Improperly trimmed nails
Heredity
Shoe pressure; crowding of toes
Repeated trauma to the feet from normal activities
The following symptoms may be present with ingrown toenails:
Pain
Redness and swelling
Drainage
Odor
Prominent skin tissue (proud flesh)
