<unk> is an irritation of skin caused by friction, moisture or irritating fabric. Prolonged rubbing on the skin may result in skin sting or burn, and development of a mild, red rash; and in severe cases may include swelling, bleeding, or crusting. It often results from body parts that rub against each other or against clothing. It commonly occurs on the inner thighs and buttocks, and nipples, groin, feet, and armpits can also chafe, although there it is less common. Severe<unk> is known as friction burn.
