Frostbite is categorized by severity as first, second, third or fourth degree, with fourth degree being the most serious. Depending on the severity of the condition, frostbitten areas may feel numb, hard and frozen, and may appear waxy, white or grey. Symptoms such as sensitivity to cold, numbness, or chronic pain may last for years. In extreme cases, the frostbitten tissue may have been permanently damaged and may need to be amputated.O.3.4.2.2First degree frostbiteO.3.4.2.2.1 The initial stages of frostbite are sometimes called frostnip. Frostnip affects only the outer layers of the skin, which has frozen. An early symptom is a whitening of the skin and a sensation of ‘pins and needles’. Other symptoms include numbness, swelling, itching, burning, and deep pain as the area is warmed. Usually, these symptoms disappear as warming occurs, but the skin may appear red for several hours.© IRATA International Annex O Page 17 of 45 2017-Aug-01
