Look For These Warning Signs Of Frostbite

Loss Of Sensation

A decrease in oxygen and blood flow to the affected area may cause a loss of sensation to pain and the feeling of cold. The severity of the lack of oxygen and tissue and nerve damage will determine whether the loss of sensation is partial or full, as well as whether it is a temporary issue or a long-term, even potentially permanent one. It is important to note as the area is re-warmed and begins to heal, blood flow will be restored, and there may be significant pain in the affected area. This is due to the fact during an episode of frostbite the blood vessels contract. The re-warming process dilates the vessels, allowing them to receive oxygen-nutrient blood, which reignites nerve endings and restores feeling to the affected area.

Burning Or Numbness

Burning or numbness is a common warning sign of frostbite. Burning typically occurs during the beginning stages of frostbite called 'frostnip.' Burning is an indication the damage has been limited to the epidermal layer and has not penetrated deeper tissues. It is also an indication the skin and nerve endings have not been permanently damaged. The burning experienced during this stage can typically be treated at home. Numbness, however, is a sign the frostbite has burrowed past the epidermal layer and has begun to damage the underlying tissue and nerves. Numbness may also be accompanied by skin that is warm to the touch, and the affected area may produce fluid-filled blisters twenty-four to thirty-six hours after the area is re-warmed.
