What are some signs of frostbite?

Frostbite occurs when skin and underlying tissues freeze due to exposure to cold temperatures. One of the key signs to recognize frostbite is that the affected area will often feel firm or hard to the touch as ice crystals form within the skin and tissues. This firmness indicates that the tissue is frozen and has lost its normal pliability.

Additionally, the area will typically feel cool, further indicating the loss of warmth due to exposure to cold. As frostbite develops, it may also appear pale or waxy, instead of healthy or pink, and the typical signs of inflammation or swelling might not present in the early stages. Recognizing these signs is crucial for timely intervention and to prevent further injury to the affected tissues.
