What are the symptoms of frostbite?

When someone develops frostbite, the symptoms usually include a prickly sensation or numbness in the affected part of the body. At first, a person may feel pain in the affected area, but as the freezing worsens, this stops. The frozen skin may look white or gray, feel cold to the touch, and appear hard or waxy. In extreme cases, blisters may start forming on the skin.

Symptoms of frostbite include numbness, pain, or itching of exposed skin, yellow or pale coloring of skin, and eventually even blistering of the skin.

At the first signs of redness or pain in any skin area, get out of the cold or protect any exposed skin—frostbite may be beginning. Any of the following signs may indicate frostbite:

  • a white or grayish-yellow skin area
  • skin that feels unusually firm or waxy
  • numbness

A victim is often unaware of frostbite until someone else points it out because the frozen tissues are numb.

Frostbite occurs when body tissue begins to freeze because of the cold. Ice crystals can form in the tissue and damage cells. Frostbite most commonly occurs in the fingers, toes, nose, and ears, which are most exposed to the environment and limited in blood flow. The victim may initially feel the cold sensation and will then feel itching, tingling, burning, pain, and numbness. If the tissue continues to be exposed to cold, it may freeze and harden. At this point the victim may begin to notice blisters, which will turn black if the frostbite progresses. The longer the tissue is in the cold, the more the body will be affected.

The signs of frostbite include lack of feeling in the affected area; swelling; and skin that appears waxy, is cold to the touch, or is discolored (flushed, white, yellow, or blue). In more serious cases, blisters may form and the affected part may turn black and show signs of deep tissue damage.
