There are several types of frost capacity, the easiest to understand and best to assess the results of the injury classification of frostbite into two main parts: surface and deep.
• Surface frostbite: The patient suffers from burning, numbness, tingling sensation, itching or cold sensation in the affected area, and the area appears frozen white.
• Deep frost: In the beginning there is a weakness of sensation and continue until the person completely loses sensation, as the skin becomes white or yellowish with a swelling and blood-filled ulcers, and the skin appears waxy and turns blue when it warms. The area is solid and may appear black and dead.
The person suffers from severe pain when the area is warm and the blood flow returns to normal. The pain also changes from a continuous light to a pulse-like sensation within two to three days. This may continue for weeks or months until the tissue is completely separated.
At first, the area appears to be intact, but this is deceptive, because the tissue is not frozen and dead when the patient arrives at the doctor, and only time can reveal the final damage to the tissue.
