The areas of the body affected by frostbite feel cold and firm. Burning, tingling, stinging, or numbing sensations may be present. Clumsiness can result from impaired motor control. When the affected body part is rewarmed, a throbbing or burning pain may result. Frostbite, like burns, is classified according to the degree of tissue injury. Minor injuries result in swelling, redness, loss of sensation, and white plaques on the skin. More severe lesions have blisters that may become filled with blood. In the most extreme cases, full-thickness freezing damages bones and muscles, resulting in tissue death and loss of the affected area.
